You own the pal version though right? If you can get in-game, you simply just need to make a save, then you could edit the save or even swap the character files in the GCM image. just ideas... i'll test them tonight, post my findings.
EDIT1
Err.. I can't find get a game save in. all i keep finding are these sav. gcs. and gci gamesaves. that when are injected into one of dolphin's MemoryCardX.RAW files causes them to be un-reconizable. Lucky I was able to hex over top the system save. And for the USA version have all mini games unlocked, ada, merceneries, and whatnot. Still can not inject in-game save.
Also tried using "GC-Tool.exe" opening the RE4.gcm and swapping theres 2 files
/ROOT/em/pl00.drs <with> /ROOT/em/pl01.drs I then notice... GC-Tool.exe corrupts the GCM and it beecames totally unplayable. "even tested back on my gamecube"
So this rules out
1) making a save inside re4 (then editing it)
2) swapping game files
>problem lack of tool support.
you guys know of another method of getting a GCI/SAV/GCS into a RAW memorycard data file?
EDIT2
aww figured out my problem "dynarec" was on.. having this disable makes EVERYTHING work yay!! now able to save to memcard, and now able to edit spawn points. have also ripped ada, wesker, hunk. ans kruaser. just missing ashley, sadler, and some cool monsters..
