Wow, nice hack. And I also did not know about that DK site, thanks for sharing it with me. Do I have your permission to add it to my DK site archive thread (http://www.dkc-atlas.com/forum/viewtopic.php?f=26&t=1861)?

I have a favor to you. Can you please translate the traffic signal segment from your 4-2 demo? That looks like something I want to implement in my fan game.

[Quaraage]

>>Gaz
No problem. Thank you!

>>VideoViking

a) ooooo (G)
This signal means "Go". You MUSTN'T stop if this is shown.

b)ooooo (GG)
This signal means "Go". And you can drive faster than signal a).

c)ooooo (YG)
This signal means "Slow Down". You should speed down if you find this.

d)ooooo (Y)
This signal means "Be Careful". You should drive in very slow speed.

e)ooooo (R)
This signal means "Stop".

[VideoViking]

Thanks, Quaraage. What codes and/or scripts did you use to make the signal lights control the speed of the carts?

[Quaraage]

>>VideoViking
That signal system isn't use ASM hack technology. It's only using sprite graphic of signal.
Players have to control cart speed themselves.
But it is not impossible signal system coding... very hard!

How to
signal sprite code (In fact, this sprite is animal ban sign.)
Add 5 signal mode. (Variable $2E ;ASM jump table)
Add the process that change the cart speed limit directly to each signal mode.
To change cart speed limit, you need to access its sprite memory, but it is not always same place.

Coding sample
Notice:This sample is based on NTSC-J version RAM address.

Spoiler!

Main code (Animal ban sign)
...
LDA $2E,x ;Get variable $2E (sprite mode)
ASL A
PHX
TAX
JMP ($????,x) ;Jump to signal mode code

Signal mode ASM
LDX #$0E9E ;Sprite memory start adrs
BRA Loop2

Loop1:
TXA
CLC
ADC #$005E ;Next sprite mamory.
CMP #$16B2 ;End adrs of sprite memory.
BEQ Main ;Not Found
TAX
Loop2:
LDA $00,x ;Get variable $00 (sprite ASM pointer)
CMP #$0158 ;0x0158 is cart's sprite ASM pointer.
BNE Loop1
LDA #$**** ;**** is new speed limit.
STA $28,x ;Set variable $28 (speed limit)
Main:
PLX
JMP $???? ;Back to main code.

It may not work well because this code was made with improvisation.

If you also want to code signal change system...
Add the process that change signal mode and graphic. If signal change is caused by killing enemy, you need to add this process to that enemy's ASM code.

What happened with your DKC1 series? I remember following these levels on NicoVideo but they're gone.

Sorry for being a bit off topic...

[Quaraage]

>>AneSDK

Hi.
For some reasons, my DKC1 series is temporary private mode.

[AneSDK]

Oh well, NicoVideo sometimes...

I'm curious, how were you able to create custom enemies in DKC1? (Like that spiked wheel that was going extremely fast)

[Quaraage]

>>AneSDK

I did sprite data hacking to create those custom sprites.
If you want to edit sprite, seek $350000+(Sprite type).
Sprite data is sequence of variable & value pair.
For example, in most sprite, variable $0F37 is speed.

Notice: This is an information of DKC1 (J). DKC1 (U) may be using different variable. DKC2/3 sprite data addresses are NOT same to DKC1, so you shouldn't edit DKC2/3 data based on this information .

[Marcolate]

Quaraage, where i can find this hack? Your ips' link is broken.

[Quaraage]

Marcolate

Oh, sorry. Please try copy & paste that URL. Then, you'll can get IPS.
I'm going to rewrite that link later

[Quaraage]

I'll publish Ver1.4 on 6/27/2016 0:00 (JST)!

Updates
New course (4-3, 4-5, 4-6, 4-B)
Sound driver update
Fix some issue

Note
4-4 is now under construction. This stage is not playable (but you can enter and goal).

[AceDarkStar]

I don't know if anyone else ran into this problem, but I am not able to finish level 2-1, since the goal post is not showing at the end of the level near the 3rd Bonus Barrel. A couple of other things don't show up either, such as the timer barrel to get me to the third bonus barrel.

I used the IPS Patch given on this forum and patched it to Super Donkey Kong 2 (J) using Lunar IPS. Would anyone happen know a solution to this problem?
