Hmm, could u give me a few example images and which ones your trying to replace? I'll see if I can get anything working. I wonder if there is any header on these images.

Absolutely, I would like to try it out.
I have the arcade version of Blitz 99 and also 2000 Gold.  Both Hdd's have been replaced with a Compact flash cards/IDE adapters.  I can pull/backup the card and make a duplicate to test with. 

If you want to put together a quick procedure or walkthrough for me try out I can start from there.

I also have NBA Showtime to test with if they were developed in a similar way.

Thanks!

Thanks for the reply Jaker!

So, that's where I'm running into an issue. Even with an unedited file (replacing a file with itself) in GEDecompressor, the program tells me the file I am injecting is too big. I've tried replacing a file with a significantly smaller head texture and I don't get the message but the game locks up. The game is only crashing when it tried to load the new image. So for these head files, I can select the players and it freezes on the transition window into gameplay.

Hey glitchrichmond,

Are the files the same size as the ones being replaced? When does it crash? on load or on the part that would load the newly inserted image?

I know this is very overdue but, I've been trying to chip away at this lately. I've found almost all the values for editing a player that I can. I can also decompress the game with GEDecompressor. It gives me all of the files that the EDL decompressor did and allows me to compress and inject graphic files back into the game. The problem I'm running across now is that when I edit the .bin files that GEDecompressor spits out (in Texture64) and try injecting them back into the game, the game freezes when it tries to load the edited texture.

Honestly, I would love to be able to edit all the graphics files in the game but even just being able to edit player faces would be pretty cool. The player faces are all 6-7KB files that are spit out of GEDecompressor. I know I'm way late on this so I understand if the window is closed, so to speak. Thanks for all the help Jaker!
