PCem (low-level emulator for 1980s-1990s IBM compatibles)
|
|
|
|
PCem is capable of emulating a wide array of IBM-compatible computers
|
|
from the 1980s through the late 1990s.
|
|
|
|
PCem is, for the most part, a single-threaded process, and some CPU
|
|
frequency governors may fail to reach high enough frequencies for
|
|
acceptable performance in emulating the higher-end models. If the
|
|
program is unexpectedly slow, consider setting the CPU frequency
|
|
governor to "performance" or "schedutil" mode temporarily.
|
|
|
|
Required: wxGTK3
|

|
|
| Building |
|
|
------------
|
|
|
|
Aside from BUILD and VERSION, the following options are available when
|
|
calling pcem.SlackBuild:
|
|
|
|
ALSA=yes # Use ALSA for MIDI output
|
|
NETWORKING=no # Disable network connectivity
|
|
PCAP=no # Disable PCAP networking (no effect without networking)
|
|
PLUGINS=yes # Build the plugin engine
|
|
|
|
This SlackBuild follows the vast majority of other SlackBuilds in using
|
|
the -O2 optimization flag. That being said, -O3 is the upstream default
|
|
for PCem. Testing revealed no obvious performance differences, but your
|
|
mileage may vary.
|
|
|
|

|
|
| Rom Files |
|
|
-------------
|
|
|
|
Rom files for individual models are required for emulation. These files
|
|
are not included in the PCem source. Once the roms have been acquired,
|
|
they should be placed in /usr/share/pcem or in the $HOME/.pcem directory
|
|
for the running user:
|
|
|
|
/usr/share/pcem/roms
|
|
$HOME/.pcem/roms
|
|
|
|
The system-wide directory is supplied by the PCem package, and the user
|
|
directory is created when running PCem for the first time. The internal
|
|
structure of the roms directory is non-trivial. See "README.md" after
|
|
installation for a list of compatible guests, the necessary location of
|
|
each rom file and technical specifications.
|
|
|
|
A "pcem-roms" collection is available, but please bear in mind that
|
|
although the roms within are ancient, they are also proprietary and
|
|
provided without a license. The collection provides a large number of
|
|
usable rom files in their proper positions within the roms directory
|
|
tree.
|
|
|
|

|
|
| Configuration and Use |
|
|
-------------------------
|
|
|
|
A variety of guest-specific settings are available through the GUI menu,
|
|
incuding the CPU to emulate, storage devices, peripherals, etc.
|
|
|
|
PCem can be configured on a per-user basis by modifying
|
|
$HOME/.pcem/pcem.cfg. This file is generated automatically at the first
|
|
run.
|
|
|
|
Keyboard shortcuts are not configurable:
|
|
|
|
Ctrl + Alt + PgDn - toggle fullscreen
|
|
(enter fullscreen: mouse capture on; leave: mouse capture off)
|
|
Ctrl + End - leave mouse capture in windowed mode
|
|
Ctrl + Alt + PgUp - screenshot to $HOME/.pcem/screenshots
|
|
|
|
To make changes to a running session (insert disks, etc.), or to create
|
|
blank disk images, right-click the screen area outside of fullscreen
|
|
mode and/or mouse capture.
