Hi. Congratulations for this amazing port, the idea to bring the whole GB experience to the C64, instead of adapting somehow the game, is simply great! Two notes:
1. I had a freeze immediately after entering my name in the hi-score, VICE 3.5 just didn't do anything else here (see attach)
2. this game really deserves a .crt version to match the full game boy feeling, since floppy access somehow breaks the poetry ;-)
