Flash Adapter

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.

8bit Flash adapter (for HW3):

Parts:

• PCB(flash_adapter.zip, 1.2mm thickness)
• TL866 SOP44 adapter
• TL866 TSOP48 adapter
• 2x40 pinheaders
• 2x SMD slide switch (LCSC Part Number C128955)

Mod needed for HW5:

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
• cut the trace going to SNES IRQ and rewire Flashrom WE to SNES WR

The modified flash adapter will still work with HW3.
