I found a tool called BioFAT that was able to split the game archives into parts.
I know I can dump them with a VRAM viewer, but I'd like to increase my knowlegde and skills by figuring out the decompression routine I just need a bit of guidance on what I'm doing. The player sprites and weapons seem to be the only things that are compressed fortunately. Of course this means dealing with compression at times, and the game I'm currently working with is Mega Man X4 (X5-6 look to use the same compression method just by looking in Tile Molester). I'm spearheading the complete re-rip of graphic archives and replacing everything with data rips.
