PSXPrev (PSX Model/Texture Viewer) (Released!)

Very cool! Still fatal errors on my machine, but I'll try with a VM when I get the chance.

Quick question - how does the tool scan for TMD/TIM/whatever data? Does it only check for the 4-byte headers/magic numbers or is there some lower-level testing to weed out false positives?
I've done lots of research on Tomba! and its sequel and everything is a "kind of" TMD. No TMD headers, but the format is very similar.

Every file type is checked by trial and error. If it gets the first TMD or TIM signature bytes, it will try to continue loading the file until it finds some invalid data, like a texture too big or a model with high vertex count, which indicates it was a false positive and it should ignore treating this entry as valid.
