Translation:

Move the cursor with the D pad. Currently selected values are reversed/white.
Press B to trigger the note. Press A to trigger the note raised one semitone.
Press L/R to change the octave.
Press select to turn "repeat" on/off, which produces a continuous note.
Press start to edit a waveform. Press start again to exit.

You can the W and M values in the formula. T is the time variable (read position in the waveform) and goes from 0-31.
The amplitude goes from -7 - 8. The output waveform is the carrier modulated by the modulator waveform.

The picture below shows the same parameters as above but with higher resolution.

My own notes: M is the modulator multiplier (overtone frequency) and W is the modulation depth.

Yeah, eventhough I don't have a clue how to use this thing yet! But I studied Japanese at the uni for a couple of years, so if there's enough interest I might translate the instructions or something. smile

Some sort of FM synthesizer for Gameboy Color. Sounds quite interesting!

Website's in Japanese though, but just click on the 'gb_fm.zip (2009.04.10版)' link above the picture of the interface to download the rom.

Have fun!

PS: I didn't make this!
