The OSCR can also program single flashroms. Supported are the same flashroms as with SNES repros since the "Flashrom Programmer" and SNES "Flash repro" menus share the same code in flash.ino.

Currently there is no flash adapter PCB for HW5 but you can modify the HW3 flash adapter.

cut the trace going to SNES CPU Clock and rewire Flashrom OE to SNES CS
