@l_oliveira Sorry to revive a dead thread but the information here has got me excited. l_oliveira I see that you say have a hacked version of the wondermega bios. do you mean for the RG-M1 and not the later xeye version? The reason I ask is because hacked mega cd1 and sega cd1 bios crash with the wondermega. while a mega cd2 etc bios does work but doesn't give the option to open the cd tray. if you do still have it id be eternally grateful if I could get a copy from you. If not then thank you regardless
There's a region free BIOS for RG-M1 on the zip file. It's X'Eye which I've not been able to fix a working region free BIOS yet.
Thanks for the fast reply sorry but where can I download the zip file from? thanks a lot btw if I can change the eprom to your bios it will change the wondermega from being a beautiful paperweight to being my main genesis system.
