It’s not often that I play games. And if I do, then my favorites are classic games. And yes, I still grow up with a Gameboy. With a large Gameboy. Since these are no longer available, I have already had one or two emulators in my hands. But what I’ve found now on the web, I’ve never seen before.
I think that’s an extraordinary achievement. An online demo can be found here. Also Grant has uploaded the sources to github.
The roms, which are needed to play, you have to get by yourself. But a short look over at Google should help you. Because the procurement of roms is in a legal gray area (at least in Germany), I will not go on it more precisely. So please download only the roms you possess in genuine. ;)
And now have fun with it. There comes to real retro feel.
There is certainly some validity but I will take hold opinion until I look into it further. Very good write-up
