byuu	dde9b4c2c7	v113.5 It seems auto-joypad poll timing is needed for most games. So that's back in as before. Instead, I added an override for Taikyoku Igo - Goliath specifically, until auto-joypad emulation can be improved further.	2019-12-31 10:22:31 +09:00

Sintendo	526df86ee6	ruby/CGL: explicitly set current OpenGL context On builds made with Xcode 11+ the current OpenGL context wasn't being properly configured anymore, resulting in shader compilation errors and a red screen.
