It's currently unknown how to read anything from

On boot, the 9.x UFO firmware reads and writes $2180-83, $2188, $218d and $218fĪs a means of decoding the routines which handle $2184-89 (probably to deterĬounterfeit/clone hardware). (See the PDF datasheets in this directory for details) The Super UFO uses the WinChipHead CH376 chip for USB communication and SD cardįunctionality.

write $218a again to disable BIOS and write-protect other registers write $2184-2189 to configure DRAM/SRAM/cartridge mappingĪnd optionally (i.e. write #$00 to $218a to enable BIOS and write-enable other registers write #$0a to $218b to write-enable $218a So, to configure the memory layout, you have to: CH376 chip is powered off / USB connection is terminatedĪll other values/effects mentioned below assume the registers are enabled. Writing any register except $218a or $218b has no effect

The registers at $2184-218f are automatically enabled when turning on the SNES,īut are disabled when launching a game, and are not enabled again if the reset Code: Select all Super UFO hardware registers
