Bizhawk-Vanguard exposes the following domains in RTC:

BSNES core

  • WRAM (Rewindable) : The console's main memory

  • CARTROM : Contains the ROM

  • VRAM (Rewindable) : Video RAM, contains Tile Data and the Tile Map

  • OAM (Rewindable) : Object Attribute Memory. "OAM contains all the properties of your sprites, such as the X coordinate, Y coordinate, tile #, vertical flip, etc (All will be listed shortly). OAM can only hold properties for up to 128 sprites at a time. Also, OAM addresses are a word in size."

  • CGRAM : Color Graphics Ram. This is where the color palette data is kept

  • APURAM : Audio Processing Unit Ram. This is where audio data is kept

  • System Bus : Domain used by the CPU for mapping the multiple areas that can be read from and written to

Snes9x core
