Description
These cores will need to have straight libc file I/O calls replaced with libretro-common VFS equivalents:
- 2048 - Uses straight file I/O for creating a save file (.srm file) - we should perhaps do this in memory completely
- 81
- Atari800
- Beetle PCE
- Beetle PCE Fast
- Beetle PCFX
- Beetle PSX (only straight file I/O used in lightning libjit in one or two files - uses fopen append)

Research direction
