I have uploaded my personal crack pack, give it a whizz see what you think:
Just replace the files in:
(make sure to back up your original files
VIVA LA KMEAW 3.55 ELITE CLUB :P
Trophies + bare basic gameplay <snip> no spoilers..
FMV + mini map + saving (blinks forever, but no hdd activity makes me think its not writing anything anywhere)
No sense of what the hell to do, just wonder around and try find a mission or something!?
In the first area jump the crates to "escape" the shonky graphics. <snip> no spoilers...
I think if SDATS are decrypted this might well fully work
EDIT: testing SDATS yielded same borked results
