Hi, I'm replying in this topic because I'm trying to do the exact same thing here, but I can't seem to get any effect from editing either m004.bin or mngrp.bin at the offset. As a test, just like Sega Chief, I tried m004.bin first, but then I also tried mngrp.bin... and then I tried editing them both at the same time. After replacing the edited files with Deling, no effect after booting up a save. Do these changes only work on a new game? I thought that was just init.out changes?
Specifically, I tried editing this, which should be the first card "Geezard": 00 00 05 00 01 00 01 76 to 00 00 05 00 01 00 01 7D, which should have, I think, changed the item to Steel Orb. It didn't change to anything, however. I know this doesn't change the text, but it should change the resulted item that ends up in the inventory when the ability use is complete. Instead, I still get 5 screws, not 5 Steel Orbs. I also tried just changing the number of screws to 1, but I still get 5. Any help?
