- one is about the speed of games like pang for the 64 bits version (they were too slow !), it's specific to the z80 emulation using the C version only.
- and the other is quite original, a graphical glitch in some cps2 games like hyper street fighter 2 and some others which was unnoticed for more than 10 years ! You can see pictures along with the discussion there : https://github.com/zelurker/raine/issues/25#issuecomment-799135733
That's the 2nd one which pushed me to make a new binary, you don't see this kind of bug everyday !
