trapezoid-core

This is the core of a PSX emulator trapezoid. It contains all the components of a working emulator, the rest is a frontend.

You can create your own frontend for this project, or use it as a server.

Components implemented

• CPU: Mips R3000A
• GPU: backed by vulkano. i.e. for now, you need a project running vulkano to use this.
• SPU: produce PCM frames that should be taken out regularly by the frontend.
• CDROM: can read the contents of a PSX CDROM, and can be used to load games
  • Support XA-ADPCM audio.
• MDEC: Able to decode MDEC frames and play videos
• GTE: Geometry Transformation Engine
• DMA: Direct Memory Access
• Timers
• Interrupts
• Memory: Hosts the whole memory as a Box<[u8]> and provides access to it.
• Memory card: will save/load memcard to/from disk, it will save to the current folder.
  • TODO: add API to control this
• Debugging: We have an API to easily create a debugger for this emulator. This is used by the frontend trapezoid.

TODO

• Multiple tracks in cdrom
• A better API, currently the API only expose what the frontend needs. and thus doesn't have access to GPU, SPU, etc...
• Better docs for the API
• Add support for more CDROM formats
• Better control over audio channels
