To run any program, an operating system needs to be installed in PCem first. It has a dynamic recompiler in the works that gives accurate Pentium support. A fork called PCem-X has slow Pentium Pro and Pentium 2 support as well, though it isn't accurate. It can also emulate numerous 2D and 3D cards, even the S3 ViRGE, which no other emulator supports.
Voodoo support used to be extremely slow, relying on frame skipping to stay full speed. However, in recent builds, this has changed with the introduction of a dynamic recompiler for the Voodoo. It is supposedly at least twice as fast as before, though some apps see up to a 4x increase in speed.
An incomplete list of OS that can be installed on it:
- Windows 1/2
- Windows 3/3.11
- Windows 95
- Windows 98
- Windows ME
- Select any IA-32 flavor of NT before Vista, it works.
- OS/2 up to at least Warp 3
- Any flavor of Linux that supports the original Pentium
- OAK OTI-067
- A couple of Trident cards
- Cirrus GD5429
- Tseng ET4000AX
- Tseng ET4000/W32p
- ATI Mach 64
- S3 Trio64
- S3 ViRGE
- 3dfx Voodoo (need another card that does VGA for this, just like the real deal.)
There is also a preliminary branch out there for RIVA TNT support. However, this code cannot be used directly with mainline, as it has a bug causing segfaults when cards attempt to use more than 8 MB of VRAM. Even when it does work, it only works for VESA games, and even then, it's only really been tested with Quake.
- PCjr and Tandy
- Game Blaster or Creative Music System
- Adlib Gold
- Sound Blaster 1.0 through AWE32
- Gravis Ultrasound
- Windows Sound System
- Innovation SSI-2001 (essentially a PC version of the SID)
