Sorry to dig an old thread, but I wanted to register to add that by coincidence I've been working on reverse engineering the data storage for the Windows 95 port of Pitfall the Mayan adventure so that I can (potentially) remake the game in C++ as to be more compatible with modern hardware/OSes. I haven't quite figured out the entire format yet as a few files seem to encoded completely differently than the rest, but I've been able to successfully dump about 90% of the sprites from that game with accurate pixel positioning and color.
The Windows 95 port of Earthworm Jim: Special Edition uses the same general asset storage structure, INIT.EW instead of INIT.PH (Pitfall Harry) and the latter uses the same "4.V4" signature for each set of sprites that puggsoy mentioned, so I imagine that the sprites for Earthworm Jim are stored in the exact same, or nearly the exact same way they are in Pitfall TMA since they were both ported by the same company.
Once I've finished figuring out the rest of the sprite format with Pitfall in theory I should be able to easily dump the sprites from Earthworm Jim 95 with little modification to my MATLAB scripts. They would all be unnamed since I've never played that game before and aren't sure what each sprite is, but it would include everything (or close to everything). The only thing I haven't touched at all with Pitfall yet is the levels, which could have their backgrounds stored in a completely different format. There are "4.V4" texture sets in the level files as well that I imagine store the sprites for the enemies and interactive environment pieces that are unique to each level, but I have no clue if the level artwork itself is stored the same way, so I can't promise anything in regards to that yet.
Anyway, I can give dumping the EWJ 95 sprites a roll once I'm done or close to done with the Pitfall ones if anyone is interested.
