Playstation for MiSTer Platform
HW Requirements/Features
SDRam of any size is required.
Bios
Only scph1001.bin tested. Rename to boot.rom
Memory Card
One card can be mounted for each controller slot.
Cards are in raw .mcd format. An empty example card can be found in the memcard folder.
You need to save them either manually in OSD or activate autosave.
Saving or loading a card will pause the core for a short time.
Video output
Core uses either normal output or direct framebuffer mode.
In Framebuffer mode you can choose to view:
- normal drawing area without any overscan cutoff
- full VRAM as 1024x512 pixel image (debug mode)
Error messages
If there is a recognized problem, an overlay is displayed, showing which error has occured. You can hide these messages with an OSD option, by default they are on.
List of Errors:
- E2 - CPU exception
- E3..E6 - GPU hangs (e.g. corrupt display list)
