How to use the core
Libretro cores are shared libraries. To use this core you will need to have installed some libretro front-end, such as RetroArch, and import the core file into it.
Requirements
The Vircon32 core requires either OpenGL Core or OpenGL ES 2/3.
What's new in version 1.4?
This version modifies savestates to include the state of the BIOS and make them more robust. This will fix graphical glitches in some games. Note that this BREAKS COMPATIBILITY with previous savestates. If you try to load a savestate saved with previous core versions it will not work.
Also, this version changes the internal name of the core variable (from enable_frameskip to vircon32_enable_frameskip). Adding the core name as prefix helps certain front-ends and configuration systems. But again, note that it might break previous configurations.
Known issues
Game compatibility should be 100%, but there are a couple of things to note about playing Vircon32 using the libretro core:
- Savestates do not save the screen contents, which are persistent on Vircon32. This is done on purpose to reduce size and complexity on savestate handling. Otherwise it might get too taxing to enable rewinding. Most games will update the screen every frame, but once in a while you can have screen glitches for a moment if you save a state during menus or screen transitions.
- There is not an easy way to change the memory card on the fly. This is normally not needed but there could be (very few) games that rely on this, like the Chip-8 emulator. These might be better played on a standalone emulator.
- On the libretro core, currently all 4 gamepads are considered connected at all times. This is not an issue, but if you run the gamepads test it may behave differently to other Vircon32 emulators.
Supported systems
The core currently works under the following systems (possibly more):
- Windows
- Linux
- macOS
- Android
- iOS
- tvOS
- Raspberry Pi 4
- Nintendo Switch (libnx)
