Danganronpa BTX FILES

Post by xperiagenerator »

Hi
Can you make a quick bms script able to decompress and reconpress this btx file format?

i m attaching a compressed btx and its decompressed counterpart

decompressed using this set of tools https://github.com/BlackDragonHunt/Danganronpa-Tools/tree/master/dr12ae but they are not able to recompress back ( i need it to mod the game so to reimport back the modded files)

thankyou in advance

Maybe you don't need to compress it back, have you tried?
Anyway without the re-compression implementation there is nothing you can do, maybe someone can write a fake compressor if he is interested.

Sure that it's possible to write a fake compressor, in your case the only problem I see is that your file is compressed-compressed: gxt->gxr->btx.
The following script should do the job automatically:

Yes, the generated files is 4 times bigger than the original.
