Removing it shouldn't cause issues. If you let the 12v wire soldered at all time it'll eventually die on its own though! FG
Nah ... this was switched on (+12V) ... "Write" selected ... then (+12V) switch off ... then rebooted which reveals it's bricked like a mofo ... lol. You can clearly see the "v1.8" in the video for Region Changer to boot. Beats me!
Funny as it hasn't worked on any of my dual BIOS systems and I have tried just doing it when doing a region swap as I like the blue swirl as I use blue led's in mine but not once have I ever gotten the black swirl to work even using the latest flasher in RC-1.
Update ... fixed Dreamcast by re-programming Flash ROM ) Also, I received my programmed BIOS chips today from Bad_Ad84 ... thanks!
