|
|
Bung Enterprises used the upgradable BIOS as a selling point for the Multi Xchanger but I do not see that any utility or BIOS file was ever released.
I assume you could flash from disc or a PC but there were never any instructions. Perhaps there is an unused function in GB Xchanger or V64jr transfer program. Does anyone know? If so, I hope there is also a function for dumping the BIOS.
I want to see if there is a disabled function for booting CD-R backups similar to the way the official Doctor V64 BIOS had backup functions that were hidden and only required changing one byte to enable.
I took mine apart hoping to see if I could remove the ROM and dump it with my TL866 MiniPro but the Winbond W29EE011P-90 flash chip is not on the supported devices list. |
