GSM on this OPL rev is the only one that can disable the flicker filter in Gradius V (SLUS_207.12) and GTA Vice City (SLUS_205.52)
enable NTSC mode and check it out (regular NTSC mod, not progressive)
so hopefully it can be implemented in the newest OPL
thanks
haunting ground needs 24 sector cache to eliminate FMV stutter
and parappa the rapper needs sector cache at 8 to boot
tested with OPL 1922... i'm not going to update because GSM is broken, and I only have a couple ZSO's on my usb
there is some kind of bug with gsm on the latest betas... the picture shifts to the right when gsm is on, with v.1.1.0 it does not happen using the same settings
i'm just using NTSC mode in a couple games
