I always regret having to post new releases so quickly, but a semi-major bug crept into v049. I'd rather fix it now, before I start making major changes that will need testing again. The problem was that the S-PPU was not being synchronized as often as it should have been, resulting in titles such as F-Zero and Super Mario Kart showing flickering lines here and there. This release fixes that.
This release also adds savestate support for Mega Man X2 and Mega Man X3, which utilize the Cx4 coprocessor; and it fixes a bug where input was still accepted even when the main window was minimized.
