AVGCART - THE average SD multicart for 8bit Atari   FPGA based multicart for 8bit Atari computers, extensible with SIO and/or ECI/PBI cables supports CAR (cartridge dump) files up to 1MB and most bankswitching types supports XEX (executable) files supports ATR (floppy image) files (read/write) - support is limited without an optional SIO or ECI/PBI cable due to Atari cartridge port constraints (e.g. SW that uses RAM under OS does not work)
