I know TB knows how the TextX.dat files are decoded(or at least partially knows).
So does he (or anyone else) care to elaborate the fileformat? I'd really like to know
Well I do now.
First, XOR EF (like missions)
Then it's a standard ILBM file with an embedded and wrong palette, it has bad entries, just use the standard palette instead.
There is no water animation, but there is stupid RLE without a specification so it's hard to decode.
I could read both TSK and TPR without any XORing, I just open them in edit.com and I see chunk names and etc.. all normal. btw, TSK and TPR tilesets are very similar with few new tiles, so that could help in decoding.. Although I find it rather unnecessary since tileset can be captured from KaM and I already figured out and captured animation sequences (forgot to upload them yet)
