Not just tried; I actually bought a license back when you had to have one prior to downloading! x)

Though I have never really sat down and worked with it, I always make sure to have the ROM around. I'll be on a 6h trainride to Berlin soon, and if i get a good seat, i might as well fool around with it again on an emulator. I technically have a cartridge I could write it to - but, i am too blind to use a normal gameboy screen ^^'
