i am ill with a cold today so i am stuck inside and very bored… so i thought i would have a go at pitch bending my super gameboy. i had a spare board left over from GetLoFi.
here is the video:
sorry for the horrible quality, i hate this camera i really do!
new video with the final product, and a better video quality
i didn’t use everything that was in GetLoFi’s kit, but yes this could all be done with just the kit that he sells for the gameboy.
the snes has a crystal, but the super gameboy cartridge doesn’t, so the signal from the Snes crystal is passed into the super gameboy cartridge and then dropped down to the 4. something mhz that the gameboy cpu needs.
when booting the super gameboy needs to be in sync or as close to it, if it is over or under clocked then there is a data drop out and it doesn’t boot properly. but once up and running you can pitch bend it all you like.
i will post up more later, i have been working with a lot of super gameboys recently (i have a stack of 10 on my desk) all with little mods done to them, and i am just working on one cartridge with everything on it, including LCD out, button breakout, pro sound, adding a link port, PS2 keyboard support etc. just about everything you can do to the gameboy can be done to the super gameboy.
the super gameboy 2 is totally different, it has a crystal on board for the link port, and it is based on the gameboy pocket CPU. but putting on a link port onto the old super gameboy is easy, you can just chop the socket part from a gameboy with all the components as well and just wire them on
