1 frame of input lag that could be removed #72

Closed Tatsuya79 closed 5 years ago

Tatsuya79 commented 5 years ago

Comparing with MAME this core has an extra frame of input lag that could be removed.

ghost commented 5 years ago

did these awhile back (think its on the forums still)

move these before the start of main loop in WinX68k_Exec https://github.com/libretro/px68k-libretro/blob/master/libretro/winx68k.cpp#L542

or better yet move it entirely before WinX68k_Exec (it can probably optimized better i lost the repo for the stuff i did back then).

I also have a closed-uncommited PR in pull request that fixes the ram and input cleanup if your interested in applying it.

Great that's working! Awesome. :+1:

Any other fix is welcome, I'm not sure what are the issues you're mentioning exactly.
