My setup: PS3 fat (80gb), latest MM and Kmeaw 3.55.
This is what I tried (with DUPLEX release):
1. FTP over
2. Apply pkg
3. Copy sfo over
Trying to load internally and with disc continues to show a black screen that I can get out of. The DUPLEX release notes copying an eboot around from Super SF4, but everyone else has this working so easily I'm trying to figure out what I'm missing. Plenty of other titles on my 500gb drive and all of them were similar (ftp over, some pkg, etc).
