DKC Atlas Forum

I need some SERIOUS help. I am making a DKC hack in a hex editor. I need to change text values, among other things. I found bank $3c on my own, but am confused by the extra text sections. Why do banks $3d and ($26? $27?) contain additional text. Is this unused? Could I use that space for ASM hacks?

[riki2321gamer]

can't you just expand the rom to 6mb or something and use the 2mb for ASM? that's what i do sometimes

[rainbowsprinklez]

Yes, I could. If I were pressed for space, I would. I guess I just want to know if that space is re-writable or if the game somehow pulls from it

Fortunately, an ample amount of bytes in the US version 1.0 of DKC are never touched by the game's code. Here's a list of offsets that I've gathered over the past several years:

Oh wow! I was just going off zeroes, and I thought THAT was a good amount. Also, minor, but there's like 30 bytes each of free space BETWEEN a lot of object maps. There's a lot of meaningless object codes in there... I wonder if these were objects that were never made? I think I found some mini drums based on their codes and pointer in bank $35, but they crash the game. Object pointer c54b for one. Unfortunately, I have no idea why. I saw these in the $3d81cc-$3d9fff range. Probably more later, but I haven't gotten there yet.

***EDIT***
I am currently going through every byte from $3d8000-$3df1dx. I'm creating a hack where I mess with object maps and some other things. Terrain though, is NOT something I'm messing with Thank you Giangurgolo and Simion32. Couldn't have been doing it without you. Also, currently, I'm only working in hex, so forgive my "noobiness".
