also is there a way to save like most emulators do? or there is just in game saving?
Just game saving. There are no save states.
when i disable it the game goes to 3% speed totally unplayable. tried in 4 games. anything else i can do? is it a matter of my hardware? is it that bad?
Enable Hardware Shader is a last resort, and there will be expected degradation of performance. Unfortunately, it will be a mater of hardware.
