uncompressing gfx is very hard, and it mostly requires ASM hacking...so its not gonna be possible for anyone that doesnt know asm.

why the hell does everyone imediatly answer every question they don't know the answer to with "uze asm or els u cnt". and you obviously didn't know the answer in answer to this poor guy's question, if you use the programs that come with LunarCompress, available at FuSoYa, a member of the board's website, you can edit several compressed graphic formats, perhaps one supported by the game you mentioned.

thats true, but also, if the gfx format isnt supported by it, then you would have to use asm, so in fact I did answer fairly right, I just didnt mention lunar compress, cause it didnt seem necessary

I'd like to know one thing! How could you find the region, where the level-data is stored, if the level doesn't start anymore? I mean: when you corrupt a rom, you change bytes in a paticular region and so find out what happens by starting the corrupted rom... If your rom simply crashed when you corrupted region X and then started playing level Y, you might have found some asm-code which was only used by that particular level. Level-data might be stored in another (most likely smaller) region... perhaps, one level is stored like this:

X0001-X0200: level-specific-asmcode
X0201-X0600: the storage where the sprites are arranged correctly
X0601-X1000: collision data, etc. ...

perhaps you just got the part where asm is stored, so try corrupting a smaller region within the regions you already found out and see what happens.

hallo
thanks for the replays.
Lunar compress does not work for the gfx in tghis game, this is bad and so i must use the orginal gfx , but thanks for the help here.

to you FloBo:
I found the region were the level data is storred by corrupting every byte of this game, the game has , when i remeber correct $10000200 byts in hex and at first I started with corrupting in $100000 steps , than $10000 , than $100 (here i found men
