Game Gear running fast after modding with a McWill display


Recommended Posts

Has anyone had their Game Gear go into hyper-active after installing a McWill LCD mod? This is the fifth GG I've put a McWill into, but this particular unit appears to have gained an extra blast processing unit along the way. The display looks great, but audio pitch is higher and games move faster. Sonic's walking acceleration in Sonic II for example is noticeably quicker. It's a VA1 unit with 2 ASICs and a 837-7719-01 board, the usual suspect electrolytic caps have been replaced, a few trace issues worked around, and it seemed to run at the correct speed with the half dead and deteriorating original display until the McWill mod was added.
