Hi , Don't know if I'm doing anything good but , here is my Erors log from running J-star victory on emu , By the way it opens and the screen is just black ( I know you know ! )
Oh cellFiber.. and Spurs.. Spurs implementation needs hard work including RE. Fiber? Well ignore those first.
E {PPU[0x5e] Thread (CRI FS File Access 2)[0x0073c104]} sys_fs error: sys_fs_open('/dev_bdvd/PS3_GAME/USRDIR/data/PS3/game/resident/game_resident_ALL_m.pak'): failed to open file (flags=0, mode=0)
E {PPU[0x5e] Thread (CRI FS File Access 2)[0x0073c484]} sys_fs error: sys_fs_stat('/dev_bdvd/PS3_GAME/USRDIR/data/PS3/game/resident/game_resident_ALL_m.pak') failed: not found
Are you sure the path to the .pak file is correct?
If you enable ALL logging you could see the current paths configured in VFS before you start to run it.
Maybe you correct the path and it would reward you with some Images.. even in RSX Debugger..
BTW. Thanks for the log. For only loadable records you don't need to show the black screen yep.
