DMG with half-speed crystal

Here you can see my "half-speed modded" Gameboy with Pro-Sound and white buttons (the simplest way to distinguish the members of my little Gameboy-family). I just replaced the original crystal-oscillator with one running at half-speed (2.097152 MHz). Just like Pro-Sound, it's a simple but very useful modification. On LSDJ you can play now one octave lower, so you can use it for bass-tracks. Surprisingly, the synchronisation with a normal DMG works also very well. The device can be master or as slave. Editing on this Gameboy is not very recommended, because the MMI is running slow as well and the screen flickers heavily. But you can write the tracks on a normal DMG and use the half-speed device just for performing the transposed track.

I tried the noise-generating software "Death Ray" from Pixelh8 on my half-speed DMG.
