Re: [Patch] Xi8088 - GPL XT system bios
I can't get CGA, MDA, or Hercules to work. It just doesn't render any video (video that was previously there stays stuck with no screen updates).
EGA and VGA both work fine.

Re: Proprietary API videocards
Only Radeon 8500 supports native Truform. Not even R200's variations do. The wide variety of Radeons I do own don't support Truform either.

Oh then I see, it probably takes a while for your GPU to copy the display-image. I didn't think that would be an issue. I have created another branch (performance_test) where I instead copy the display-image to a temporary buffer and then copy that to the GPU later, it might help. That fixed it rig...

Re: [Linux] GUI discussion
Hmm, the rendering is performed in a separate thread from the emulation so it shouldn't slow it down too much. Not sure what could cause that. Looks like I made a mistake in my analysis. I get equally low performance with both OpenGL and GL3, but with software rendering, I get full speed. Even 386S...

Re: [Linux] GUI discussion
I looked at the source for RetroArch and found out that they set the GLSL-version manually if it isn't defined, which is the case with this shader. I've added that as well and updated the branch, maybe it will compile now. That just broke everything and now GL3 won't work even without any shaders (...

Is there a way to get the sharp-bilinear shader (in libretro's pack retro/sharp-bilinear.glslp) working? It essentially completely fixes uneven pixel scaling by scaling the image evenly to a high resolution, then downscaling back to your preferred resolution using a bilinear filter. The pixels are s...

Re: [Linux] GUI discussion
I can't get either pcem or your fork to recognize any ROMs lately. It worked just fine in previous versions (I have all of my ROM names lowercase), but something seems to have changed preventing it from working.
I'm using Debian 9, and I've never had this issue in the past.

Re: bleem! Gives BSOD on Open
ATAPI emulation at this point doesn't make any early W9X ASPI-driven PSX emulator happy. The farthest you'll get in any PSX emulation in PCem is launching the debugger on the bios in PSEmu Pro.

Re: [Q] Roland SC-55/SC-88 emulation?
He could always leave the ROM dumping to someone else and not distribute it, like many emulators do with their respective BIOS.
I am planning on getting an SC-8850 sometime in the future anyway, so It's not a huge deal to me.

I am also having major problems with this. PCem is always running at 100% for me, and I am getting around half a second of latency from when I do something to when the sound is supposed to play. This happens both with the PC Speaker, and with an audio card.
