PCem-X is an open-source, low-level PC emulator. It focuses on PC hardware from the 1980's and 1990's. A variety of operating systems can be installed in the emulator, which can then be used to launch programs. Some parts use HLE, however, such as the Game Blaster, Sound Blaster, and the keyboard.
PCem-X is now out of date, as OBattler is now focusing on contributing to his new emulator based on PCem, 86Box. He does still maintain an experimental build, however, which has some additional features and bug fixes over mainline, albeit being a bit less tested.
PCem-X is a fork of PCem that emulates hardware from the 1980's and mid-1990's. It does not emulate the operating systems as well, however. To run any program, an operating system needs to be installed in PCem-X first.
An incomplete list of operating systems that can be installed on it:
- Windows 3/3.11
- Windows 95
- Windows 98
- Windows ME
- Windows NT 3.1/3.51/4
- Windows 2000
- Windows XP (BSODs on emulated Pentium 2.)
- Windows Server 2003
- Some older flavors of Linux. (There's a bug that was introduced between 2.6.18 and 2.6.26 that crashes PCem-X.)
- A couple of Trident cards
- A metric ton of Cirrus cards
- Tseng ET4000AX
- Tseng ET4000/W32p
- ATI Mach 64
- S3 Trio64
- S3 ViRGE (The only working 2D and 3D card on this list.)
- 3dfx Voodoo (need another card that does VGA for this, just like the real deal.)
- Nvidia RIVA 128 (only does VESA, not ready for general use.)
There's also a branch that has preliminary Nvidia RIVA TNT emulation as well if you feel like emulating a video card with 16 MB of VRAM.
- 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)
