DKC Atlas Forum

I'm starting this topic because I found something interesting while researching with DKC3 RAM addresses.
----------
You get the maximum of 15 banana birds in Donkey Kong Country 3, well I found the RAM address for the banana birds and I was curious what would happen if you had 16 banana birds, so I made a PAR code.

7E05CD10 - 16 Banana Birds

So I went to Wrinky's Save Cave, used the Turbo Ski to get there, the birds took me to there mother, and the mother complained that I haven't found all her Banana Birds, I was teleported to the Pacifica part of the island with the Turbo Ski.

The collision was still there, K's Cache had collision detection, etc., this is more proof that Pacifica was going to be in the original DKC3.

That is interesting, but it seems like fairly predictable behaviour:

1. Game recognises that you have all banana birds, so you get taken to the Queen
2. Game does verification once you arrive in the clouds; number is != 15, so you are sent back to the map

To me it seems like a simple coding inconsistency; one routine checks that all birds are found, one checks if total number = 15. You would normally be in the gyrocopter if you manage to visit the BBQ (lol) without all of her birds, but since you PAR'd your way there, the game just spits you back to the world map with the vehicle you last used.

As for the collision detection; I guess it just follows the rules of the rest of the map, which doesn't surprise me at all.

I don't think there's any proof here that Pacifica was meant to be in DKC3 SNES... still, I like your theory.

What I was mainly proofing is that there is collision detection in that area, where in normal play, it's unused.

Anyways, I'm working on documenting DKC3's RAM, it will help with hacking the game.

I done some more research on hacking DKC3, first of all, ExHiROM has to be ASM'd with a special XKAS version, I'm actually still researching on ExROM hacking, when I expand DKC1 and 2 to 8MB ExHiROM, there ain't any gameplay problems, but for DKC3, it messes up the super compressed tilesets.

More info!

Just a week or two ago, a ZSNES unofficial version was released by FuSoYa, it supports 8MB ExHiROM.
Maybe in the future, ExHiROM DKC hacks will be supported and possible.

Whoa, that's cool. Gotta love FuSoYa for his persistence.

[Markster]

Do you think ExHiROM DKC hacks will be possible in the future, I remember I used to have a XKAS unofficial version that supported ExHiROM.

[Markster]

While researching on DKC3's data, I copied data from an SPC, and a lot of that data found a match in the ROM.

Maybe DKC1, 2, and 3 music hacking will be possible in the future.

Did it include musical instructions, such as type of instrument, note, tempo, percussion?
