Graphics Synthesizer Mode Selector 0.36.R

—-
[Default values are marked in bold]

Open PS2 Loader 0.9.3 features Graphics Synthesizer Mode Selector aka GSM 0.36.R version. GSM allows you to force videos modes in-game. GSM is disabled by default so you need to enable it if you want to force video modes [Press Configure GSM in the Game settings screen.].

GSM is not a general option anymore – like in 0.9.2 – but it’s per-game specific now. You can enable it for a game and let it disabled for another, enable progressive for one, not enable it for another because it’s not compatible etc… GSM settings will be saved in <game_ID>.cfg files (stored in CFG folder).
