Yeah, on PC. I can do it on NES Classic. I found an emulator, Mednafen. And it seems to work great. Except that I can't get it to run full screen properly. It runs in full screen, but the game is in a little box. I'd like to get it to run in fullscreen, but completely enlarged with the proper aspect ratio.
I found the config file where you can change settings, (the emulator isn't a gui emulator), but I don't know which settings to change. I see where I change it, but I don't know what to replace the default setting with.
What's the emulator you were talking about ?
Oh geeze. The best Turbografx-16 emulator is Magic Engine. I have done extensive work with this emulator, and have even made stickied topics from over a decade ago about how to run Turbografx-CD games on it. It's only drawback is that it is a "paid" emulator. But, you can find "registered" versions, quite easily. I have every Turbografx-CD game, legitimately, and have ripped them all. Not only that, I have also made a separate set of ISOS, without music, so games can be played at much smaller, Super Nintendo equivalent, sizes.
My topic I made on Magic Engine years ago!
