Oh yeah, RChickenMan, I meant to tell you in a earlier thread you posted: The "button lag" you appear to be experiencing is due to either a slow frame rate (how many FPS does it show inside the brackets?) or an older version of Morphgear with problems (2.1.0.0 is very old...).
I have played many GAPI games and also many SNES and Genesis games without sound (running at 30+ FPS) and can tell you there is not a hint of button lag. It plays as smooth as my younger sister's gameboy.
However, when I do enable sound in Morphgear and start getting 12-20FPS I do notice "actual lag" which can be confused as "button lag".
