# SGB Music Test ROM

## About

Demonstration of making the Super Game Boy play SNES music. Currently this will

not work on a bog-standard GameBoy emulator (not even BGB)

The SGB reads this music data by reading the screen when prompted by a `SOU_TRN`

packet. As a consequence, the screen will be full of garbage, and it should be hidden from view by using `MASK_EN` before the data is rendered to VRAM. This is not implemented here.

The music data itself is in the [SBN format](https://github.com/LuigiBlood/SBN2SPC/blob/main/README.md) (a very simple, block-based container

for SPC music data basically)

The SPC data itself is just song sequence data in the basic [N-SPC](https://sneslab.net/wiki/N-SPC_Engine) format.

The instruments are all coming from the Super Game Boy itself, in other words,

the Super Game Boy has a "soundfont" built in :p

This ROM has only been tested with SGB1/SGB2 with BSNES.

Included is a **MIDI to SBN** script, which you can use, distribute, modify, whatever.

## Building

What do you need?

* RGBDS

* Python 3

* Python Mido package (just do `pip install mido`)

* GNU Make

* A Super Game Boy (1 or 2) boot ROM, if you're gonna test this in BSNES

How build?

* `make`

How test?

* In BSNES, go to System -> Load Special -> Load Super Game Boy Cartridge

* Load the boot ROM to Base cartridge, and the built ROM to Game Boy cartridge
