I'd really like an updated DKC3 Sprite viewer!
Great hacks!

Most likely a couple of weeks from now, when I don't have a final project and two exams hanging over my head. I would like to back-port a few of the new features of this one to the DKC1 and DKC2 sprite viewers (namely, the dual-palette functionality and the ability to view all sprites with their proper graphics; the latter of these is done with the exception of displaying the graphics locations for these sprites), and release all three updated versions simultaneously.

Since there seems to be some demand for this, I've quickly slapped together a DKC2 Sound Test patch. This patch disables all music in the game, and hijacks the pause routine to have a Sound Test Menu.
Press L or R to cycle through the different music/sound banks (this takes time, as sound data and sample data have to be written to SPC RAM) Right or Left on the directional pad increments or decrements the sound value, respectively. The Y Button plays the sound effect with the selected value.
Here are what the bank values correspond to:

Excellent, another handy utility!
You know, as you're popping out these useful and innovative patches left, right and centre, I'm beginning to picture an ultimate customisable trilogy of DKC(/2/3) hacks in the future, which contains all of the tweaks and options you're developing - all rolled into a single IPS for each game. They would essentially look and play exactly like the games we know and love, but would have subtle (but (probably) easily accessible) menus/toggles for all the features, settings and alternative modes you've been developing. I do wonder how many of your hacks are 'compatible' with one another - as in, they don't make conflicting changes to game data, etc... it could be really awesome to have a single hack for each game provide the original adventure, and so many different ways to explore and appreciate it.
Inspirational stuff yet again.

Leave this one to me. I'll get to ripping them out to files immediately (we need this for DKCLB)...
Thank you, Mattrizzle!
EDIT: Thiiis could take a while to do. It's not just 7F SFX, but 7F for every single bank (duplicated or not, how the heck am I supposed to know?).
EDIT 2: Seems to be the same sounds but with a different set of source audio.
Mattrizzle, any insight into this? I don't want to waste my time trying to record everything and find out I could have done things a faster way (don't worry about my recording setup, I have that covered. I'd just like to know what's going on with the SFX and whether they have the "same" sounds for each "bank").

That looks beautiful, Matt.
I personally think this sunset aesthetic is a much more fitting 'end of the adventure' theme than the bright daylight look of the original Gang-Plank Galleon. I immediately noticed the Gangplank Galley palette similarities, and I think it works smashingly in this context!
Would love to see this as part of your magnificent and ever-evolving Boss Blitz.

I was able to extract the path data from DKC2 as vectors! I think there's some unused paths there too..! I'm writing a technical specification as we speak.
And fantastic job, Matt! Really fits the theme.

Thanks, both of you! I removed the spoiler
And Matt, you're right. It even has a point assigned to it in the coordinates, unless I'm mistaken.
If any of you guys have an SVG editor, here's the file so you can knock yourselves out. The first polyline is the first path in the path table and the second one after that, etc. They're all on top of each other, so you might have a hard time dismantling the spaghetti!
EDIT: Behold, all the paths overlaid to the maps I guessed they're supposed to go onto. Triangle means the beginning of a path, dot means a stop, respectively.
Looks like I was wrong about the unused paths. Well, back to writing the spec I guess. Who knows what's next up ahead

Let it snow...
In order to be able to use the layer 3 snow, I had to shift the palette lines used by everything else... Fortunately, the boss lair archetype has an unused palette line.
I never understood why the GBA version added stalactites to this battle. There are clouds in the background, and none of the maps have a cave entrance where the boss level is.

That's... a good point.
I never noticed those clouds, and I figured the boss battles took place in caves — mainly due to them being so dark looking in otherwise (typically) well-lit environments... but it makes sense that the battles are outside, what with the piles of bananas being so visible on the world map...I'd say there's a good chance that Rare's DKC GBA port team forgot/never knew that these 'lairs' weren't actually in caves.

Ever wanted to see what the DKL3 prototype would be like in color? Well, soon you will be able to! I took the Japanese version and ported the level layouts from the English prototype. I also changed the required time of Whiplash Dash to 45 seconds like it is in the prototype (it still isn't too hard to beat).
I'm not going to release this yet until it is finished, and currently there are some nasty bugs in the bonuses that are unique to this hack. I guess the bonus stages use different sprite tables from the rest of the game:
So that will need fixing -- I'll work on it soon. I'll probably do a 103% test run of the game before releasing it, which I have also done for past DKL3 patches. There are some other things that I may or may not do:
- Add the map animations and the most recent time in Time Attack, which the English and Spanish patches currently do, since the official English versions all do this. (Maybe get Bear's animation working again, too...)
- Recreate the bug where extra live balloons freeze for a moment before popping. (Unfortunately, this may be difficult for me to do -- I'd have to figure out what causes the bug in the first place.)
- Merge this with the English patch, using the text strings that were present in the prototype (e.g. the various typos like KROOL in the cast list, and him referencing the watches when approaching him in K. Rool's Last Stand).
What do you all think?

Amazing! You never fail to impress, Blaziken. That DKL3 prototype might just be neglected if it weren't for you. Remember, I'm like your biggest fan Blaziken. I'm always excited for your projects and such. If I could one day experience ROM hacking to follow your footsteps... Anyways, I love it. I love the Japanese DKL3 GBC convert to English, I love the typo fixes in it, everything. Color hack from 2008. You are my favorite ROM hacker out of them all.
I can't wait for this new project. Good luck!

Thanks! While I do seem to get a few people more interested in DKL3, I doubt the prototype would be completely forgotten if I didn't spend my time hacking DKL3... Also, I fixed the bugs I caused in some of the bonus stages. It turns out that the bonus stages do use different sprite tables after all. Here are new screenshots:
Now I just have to do a 103% test run and if all is well, I'll release it. Also, I forgot this in my last post, but I wonder if I should make the Time Attack data compatible with the prototype. The prototype and retail ROMs use slightly different Time Attack checksum mechanisms, so saves between the prototype and retail ROMs aren't compatible in this part of the game (without hacking). Right now, Time Attack data in this hack is compatible with the retail ROMs, but not the English prototype ROM. I can choose the former or the latter, but not both -- what do you all think?
EDIT (Apr. 15, 2013): I have finally finished the hack! Here is the download link:

Enjoy playing the prototype in color! I also wonder if I should merge this with the English patch to make the text changes...

Here's a small patch that fixes the backup file bug in the Japanese DKL3, as described here:
viewtopic.php?f=11&t=1950
The patch itself is in the link below, and it is available in IPS format (for the time being):
http://www.mediafire.com/download/caodedoblb65cp2/DKL3J%20-%20Save%20backup%20fix.ips
Using this patch, if you have a corrupt save file, but working backup copies of the save file, the game will now load the working backup save file properly, as was originally intended by the developers. While this may not be needed much on an emulator, it could be helpful when playing on a real Game Boy, as cartridges are prone to data loss.
If you want to see this for yourself, open a hex editor and edit the data in offsets 0x00-0x4F (for file 1), 0x50-0x9F (for file 2), or 0xA0-0xEF (for file 3). With the patch, even after editing this data, you'll see that the save data will be what it was before you edited it (assuming that you don't mess around with the backup copies further down in the save file). Without the patch, you will see your changes to the save files when you play the game, which means that you're playing a corrupted save file.
While the bug exists in both DKL2 and DKL3, this patch will only work for the Japanese DKL3. I'll come up with separate patches for all other games eventually, and I'll eventually update the English GBC patch with this bugfix as well. (Coming up with patches for the other games will be harder, though, as all the DKL ROMs, except for the Japanese DKL3, are extremely tight on empty space, and I will likely have to expand the ROMs to be able to do this. But at least it will still be possible!)

So I downloaded Donkey Kong Land 2 on the Virtual Console the day it was released in North America (which wasn't too long ago), and I noticed a change in Lava Lagoon, Glimmer's Galleon, and Clapper's Cavern. In those levels, whenever there is any flashing going on (such as when the level is about to become completely dark in Glimmer's Galleon), it flashes noticeably more slowly on the 3DS than it does on the Game Boy. Here's a comparison in Glimmer's Galleon (it's similar in Lava Lagoon and Clapper's Cavern):
I know that not everybody here has a 3DS (and I don't think that everybody with a 3DS is going to play DKL2), so I decided to make a patch that replicates this change. You can find it here:
http://www.mediafire.com/download/3n6phmx2fpkbjg3/DKL2+-+Glimmer%27s+Galleon.ips ← (Old patch, only here for historical reasons)
http://www.mediafire.com/download/ub5eye7dr7q47a8/DKL2_-_3DS_VC.ips ← New patch! The previous patch only modified Glimmer's Galleon; now this one also modifies Lava Lagoon and Clapper's Cavern.
To be clear, I didn't extract the ROM from the 3DS (I don't know if that's possible); rather, I took a Game Boy version of the game and made the same change from scratch. I compared the behavior of this patch closely to the behavior I saw on the 3DS, so this should be accurate.
This should work on both the English version and the Japanese version, as the offsets for the ASM code changes are the same.
If anybody wants me to post the ASM changes I made, I can do that.
EDIT: I initially only noticed the change in Glimmer's Galleon, but I since noticed the change in Lava Lagoon and Clapper's Cavern as well. I updated the patch to reflect this. I also made a note that the patch works in both the English and Japanese versions, whereas I was previously uncertain that it worked on the Japanese version.

Here is a small hack for DKL2 and DKL3 that lets you keep the Banana Coins and Bear Coins you have collected, even after turning off the game. Normally, when you turn on either game and select a save file, your Banana/Bear Coin count resets to 0, but with this hack, the count will be whatever it was the last time you saved. This is similar to DKC3, as well as the GBA version of DKC2.
This is actually unused behavior (which was very recently discovered); when saving your game at Kong Kollege or Wrinkly Refuge, your current Banana Coin / Bear Coin count is actually saved to SRAM offset 0xA009 (file 1), 0xA059 (file 2), or 0xA0A9 (file 3). (When looking at a .sav file in a hex editor, these offsets would correspond to 0x0009, 0x0059, and 0x00A9.) And when you load a save file, this count is then written to HRAM offset 0xFFB3 (or 0xFFB2 in the Japanese version of DKL3). Sounds good so far... except that when the Krocodile Isle / Northern Kremisphere map is loaded afterwards, this byte (0xFFB2 or 0xFFB3, depending on the game) is then reset to 0, so you lose all your Banana/Bear Coins. This is part of a subroutine that sets a few bytes to 0. I am not sure if resetting your Banana/Bear Coin count to 0 was intentional or not. In any case, all this hack does is change two bytes to remove the code that resets HRAM offset 0xFFB2 or 0xFFB3 to 0.
And now for some links to some patches. Be sure to pick the right game and version!
(Now that this unused behavior was discovered in DKL2 and DKL3, I wonder if it's also unused in the SNES version of DKC2?)
This is actually unused behavior (which was very recently discovered); when saving your game at Kong Kollege or Wrinkly Refuge, your current Banana Coin / Bear Coin count is actually saved to SRAM offset 0xA009 (file 1), 0xA059 (file 2), or 0xA0A9 (file 3).

I've overhauled my Cranky level hint fix patch. Instead of an IPS patch, it is now an Asar ASM patch. Remaking it in this format allowed me to implement conditional statements in the patch, which means it now works on every version of DKC (except the competition cartridge, for obvious reasons)!
Download the new version here: dkc_cranky_lvlhint_fix_asm.zip
After spending some time analyzing the text, I've made a few interesting observations, most of them related to the hint for one particular level:

After spending some time analyzing the text, I've made a few interesting observations, most of them related to the hint for one particular level:
- In the French translation (top right pic), the hint for Trick Track Trek (Trajet Toc Toc) was accidentally assigned to the incorrect world -- it appears in Gorilla Glacier (Glacier des Gorilles) instead of Kremkroc Industries Inc. (Kremkroc et Kompagnie). Given that these hints are unused anyway, it's no surprise this wasn't corrected for European version 1.1.
- The German translation (bottom left pic) is the only one lacking a hint for Trick Track Trek (Trick Track Treck). In its place is an exclusive hint for Oil Drum Alley (Oelfaß Boulevard).
- Not all of the languages have an equal number of hints. While English and Japanese each have 27, German is missing one for Orang-utan Gang (Gang Orangutan), and French is missing five -- Barrel Cannon Canyon (Canyon du Tonneau à Canon), Snow Barrel Blast (Bang Neigeux du Tonneau), Ice Age Alley (Allée de l'Ere Glaciaire), Croctopus Chase (Course de Kroctopus), and Elevator Antics (Ascenseurs Excentriques).

How does an ASM patch differ from an IPS patch? Are there other advantages to using ASM over IPS? Furthermore, is it possible to create an ASM patch?

Asar is an assembler. ASM files are like source code files: they contain 65c816 code, which is the assembly language the SNES uses, and can also include comments, define statements (variables), and macros (shortcuts for sets of instructions), and conditional statements (e.g. if, else). When you run Asar, this source code is assembled into SNES machine code (binary).
In this case, I used conditionals to determine which version of DKC is being patched by checking the values of bytes in the ROM's internal header (NOT the copier header). Specifically, the country ($80:FFD9) and revision ($80:FFDB) bytes. Depending on the values here, I set certain variables to different values, so that the correct location in Cranky's text routine is hijacked for each version. For instance, in US version 1.0, $80:ED1F is the correct hijack location. In European version 1.1, the equivalent location is $80:ECC0.

Thanks for fixing that Mattrizzle. I always loved that patch but it froze on bosses. Are you still working on those Boss Rush hacks still?
EDIT;I'm getting errors:
this is on a clean DKC 1.0 ROM

Is your ROM a headerless smc file? If so, change its extension to sfc.
If the ROM's extension is smc, Asar will assume it has a header. If it is sfc, Asar will assume it doesn't have a header.
(I tested this patch with headerless ROMs, but not headered ones!

Here's a little teaser for something that I am in the middle of working on... custom demos for Donkey Kong Land III! For now, I am providing an .ips patch which contains four custom demos in the GBC version, viewable on the title screen:
http://www.mediafire.com/download/o7rj3 ... +demos.ips
This patch should be applied to a clean Japanese GBC ROM. (It also contains English patch v1.2 as well, though I can make a separate patch that only has the demos if anybody wants.)
As in the original game, pressing Select, Left, Up, or Down will change the demo that you will see after waiting on the title screen. The new demos contain the following levels:
- 0 presses: Rocketeer Rally
- 1 press: Rainforest Rumble
- 2 presses: Black Ice Blitz
- 3 presses: Ugly Ducting
The demos in the original game are also here as well. They are unchanged, with the exception of Jetty Jitters to fix a desyncing issue in the vanilla GBC game:
- 4 presses: Jetty Jitters
- 5 presses: Rickety Rapids
- 6 presses: Whiplash Dash
- 7 presses: Deep Reef Grief
I created these custom demos with a separate ASM hack that records button presses while playing any level and saves this data to SRAM, but I haven't released it yet because I still need to iron this out (I've seen occasional desyncs). I'd also like to make a tool to extract this saved data and insert it into the ROM, but I haven't started this yet, and I don't know when I'll finish it (due to limited free time). But for now, you get to enjoy custom demos!
And eventually, I'd like to make this work with DKL2, and maybe even DKL as well. But I haven't started those games yet. Don't ask me when I'll be done with all of this!

I'm glad you're interested! I'd like to upload a video of it, but I gave up on YouTube years ago and have no intention of going back. Maybe if there's a better alternative to YouTube, I'll consider making a video of this hack...

Here's a small hack that I made for DKL3 GBC -- this one replicates the behavior in bonus stages in the SNES versions of DKC2 and DKC3, in that when you're running low on time in a bonus stage, the music will continually speed up.
Specifically, the music tempo will speed up once the timer reaches 10 seconds, and will speed up again once it reaches 5 seconds.
Here are some links to patches. The first one simply does what I described above, while the second one also contains my English patch (v1.2) as well. Both of the patches should be applied to a clean Japanese DKL3 ROM:
While I only briefly tested this in a bonus stage, it does work, and doesn't appear to break anything else.
Now for a more technical explanation below, for those who are interested:
Finally, I plan to make a similar patch for DKL2, but most of Rare's games are more difficult to hack than DKL3 GBC or DKC GBC, because they're extremely tight on space, and adding anything new to these games requires expanding the ROM, and then repointing lots of code and data thanks to the Game Boy's 16KB banks. That's not to say that it's impossible, but it takes extra effort. By the way, this is largely why most of my hacks are focused on DKL3 GBC rather than the other games.
(I wonder if I should officially make this part of my English patch if I ever make more improvements to it, as opposed to a fork? Hmm.)

And now for a minor hack for the SNES version of DKC3: This fixes Kiddy's color palette in bonus screens when the COLOR cheat is used. Specifically, in the retail game, Dixie's color palette was properly adjusted to dark purple, but Kiddy's is still blue. This hack makes Kiddy's palette green as it should be. This change was backported from Japanese v1.1, the only known revision that assigns Kiddy's color palette properly.
Below is a link to the IPS patch. It works properly on both the vanilla American and European versions (since their palettes are stored in the same offsets).
http://www.mediafire.com/file/8pfvhmk0w ... or+fix.ips
This patch should be applied to a headerless ROM (which is exactly 4,194,304 bytes in size).
And here are screenshots for your pleasure:
For reference, here is what the palettes look like in the retail versions:
Finally, as you may have guessed, I'm slowing starting to learn ROM hacking for the SNES, because I'd like to focus on systems other than Game Boy sometimes. Mainly, I'd like to learn assembly for it, which will naturally take a while to do. I actually found the offsets for these palettes using a disassembler in bsnes-plus, though this isn't an ASM hack since no code was modified. Nevertheless, I plan on doing more with it. One fairly ambitious thing that I'd like to do is backport some of the bug fixes from the European and Japanese versions to the American version, which has the most bugs. I imagine that it will be difficult to do, but I can at least try it! And I am sure that learning assembly will be necessary for this...
And in case you're wondering, I haven't given up on Game Boy hacking completely, just taking a break from it for a while. So don't worry about that!

What assembly tricks did you learn from the Game Boy releases that we could see once you move on to the SNES? This would be a major breakthrough that would help DKCRE immensely as well as my dormant DKCX game.
