This article is about implementing the following Sega Saturn modifications: Region-free BIOS, FRAM, and switchless 50/60 Hz.
But first, we’ll need to go back in time a decade or so. Back then, I was modifying my “This is COOL” skeleton SegaSaturn (HST-0021/HST-3220) like crazy, stuffing everything inside that I could find:
- V2 modchip
- The ultimate Sega Saturn Switchless Mod
- A/V out mod for EU SCART cables
- EU Type-C PSU to supply 9V for the A/V out mod
- Region-free BIOS chip
