I forgot to do an end write-up of this, and there doesn't seem to be too much interest in this. But I guess I should just give you the unfinished work I did. So this is what I made back then to decode the images //decode the custom RLE CONTAINS ERRORS ATM std::vector<char> MisakaArchive::decodeRLE(s...

I'd say that your best bet is to look at the various SDK releases for details. The most relevant seem to be: sp/src/public/studio_generic_io.cpp sp/src/public/studio.h look at struct studiohdr_t (the datadesc is the datamap_t) and sp/src/public/datamap.h look at struct datamap_t edit: Looks like tha...

Anyways it's basically like this: |Bit # | 1 | 2 | 3 | 4-8 | |-------|----------|--------|---------------|-----------| |effect | lookback | repeat | is...

So what I've got on them is this: http://i.imgur.com/6UOprCo.png stru...

realized that there's a seperate fourm for images so I posted my findings regarding the image format there

I'll be posting any findings regarding the "PSC6" headered 3D model/animation format here

I'm currently trying to extract the 3D models from the PSP game "toaru kagaku no railgun", which should use the same format. I've uploaded the file here ( edit: I just read the rules, is linking this now forbidden? I'm confused because there's already links in this thread ) for people who ...
