I apologize in advance if this infomaton is readily available. I'm looking for region mod infomation on the Turbografx USA model, Only Located a few articles but mostly dead links. From my understanding the center cartridge (5-6?) pins need to change postion from JAP to USA with a switch. Any help would be greatly appreciated. I also read that region mods can interfere with the Everdrive? True?
http://www.mmmonkey.co.uk/multi-region-pc-engine-turbo-grafx-16/ My CoreGrafxII has the gamedoctorhk region-mod and I never had any issues with my v1.2 Turbo Everdrive, KRIKzz doesn't recommend it though. Also, the Turbo Everdrive is region free and should work just fine with most roms (good dumps, eg. GoodPCE v1.09a).
It's 8 pin BTW, and the easy part is on USA console to play Japanese games. Japanese consoles need one more mod to make it work with USA games, hacking the frickin' tiny pin on one of the chip. If you want to fix your Japanese console and your soldering skill is comparable to a 5 year old kid or none at all, you better pay someone to hack your Japanese console.
