Hey, thanks for playing, and thanks for the positive feedback!
You're right about the printer - you need an official GB Printer (Or use GBE+ emulator) and the rock will crumble away for you to continue!
You can use BGB for the SGB if you configure joypad 1 (you can technically get away with just one extra joypad, you don't need 4!)

And the Color dungeon.... if you are stuck with the rock in winter... you need to go back to Autumn and push the rock off the cliff then. Then it will stay put, and then go to Winter, and the water will have frozen below the rock - allowing you to push it out the way!
Hope that all helps?!
Steve
