nyandeyanen Posted August 24, 2020 Share Posted August 24, 2020 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.

nyandeyanen Posted August 29, 2020 Author Share Posted August 29, 2020 It turns out that the 200 ohm SMD resistor next to the xtal/oscillator was causing the speed issue. I replaced that and the speed is back to normal. Quote Link to comment Share on other sites More sharing options...
