Flashing the BIOS on a master system 2

[Released: 1985] One of the most unusual features of the Sega Master System is its dual media inputs: one cartridge slot and one card slot. The card slot accepted small cards about the size of a credit card.

Flashing the BIOS on a master system 2

Post by /markiiisystem »

Hi folks.
Been tinkering around with the Master System 2 for a while now, looking at the various mods etc.
I've seen that there are different versions of the BIOS (alex kidd, Sonic etc) and was wondering if anyone has ever swapped the chip out for a socket and replaceable chips? Is this a mod that people do?
If anyone has any guides, recommended parts etc I'd be interested to see them?
Ta!
