I'm not really doing gameboys anymore. But I will work on a schematic when I get a chance. I'll make it work with the 2n3904 transistor or a dual op amp with a trimmer so people can set their own brightness preferences.
The only problem is that I don't know the full range of the output, so the trimmer will fix that.
That would be awesome. As I mentioned i can do solder this to that things
