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=yes # Enable 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. diff --git a/system/pcem/pcem.SlackBuild b/system/pcem/pcem.SlackBuild new file mode 100644 index 0000000000..f3fa93810a --- /dev/null +++ b/system/pcem/pcem.SlackBuild @@ -0,0 +1,150 @@ +#!/bin/bash + +# Slackware build script for pcem + +# Copyright 2022 K.
