Kazuya Takahashi (NES Driver)

Kazuya Takahashi

Released 1988-07-14 Programmers Kazuya Takahashi Language 6502 Assembly Formats Unknown (ASM?)

Kazuya Takahashi is an unofficial name of the sound driver used in various Famicom and NES games, and was programmed by Kazuya Takahashi.

Output

The driver outputs to the 2A03, but never uses the DPCM channel. The driver also contains a glitch where whenever the triangle channel isn't playing a note, it hangs a low C until another note is played. This, along with the instrument design, gives it an identical sound to Odyssey Software's sound driver.
