Wii U PGM games performance issues Knight of Valour #221

Closed cecilmax closed 6 years ago

cecilmax commented 6 years ago

Hello,

I just try another game. Knight of Valour 1 Please note that game work perfectly on final burn alpha 2012 on wii U.

The game load but it is slowed down and sound is more than just choppy it is very very choppy.

I also try oriental legend 1 and 2, same bug. Note: oriental legend also work fine on fba alpha 2012.

I tested knight of valour 2: it is much more slower, the pgm logo is slide down the screen slowly at the beginning.

That's not a bug and not something i can fix, current fbalpha needs more ressources than the version from 2012. It's also probably going to get worse with every new release.

Ah ok, splitting the core into multiple smaller cores could it be a solution ?

Well, perhaps with a lot of other modifications : i guess some part of the code in the m68k and arm7 cpu emulators are not absolutely needed for pgm emulation, and you could probably somehow underclock them too. Actually i already looked into adding speedhacks to the pgm driver a few months ago, but it's too much work for little benefit when you know a computer like the rpi3 can emulate them properly.

Ok, so that mean the Wii U is not powerful enough for thoses games. Ok lets try to fix real bugs like asterix and d d crew, theses games have graphics glitches :)
