quartet-intro

A cracktro for Quartet, courtesy of AYCE :)

Careful when cloning that this repo uses hardware.inc, superfamiconv and rnc_propack_source as submodules.

Building

You need quartet.gb at the root of the repo (not provided) and RGBDS installed. Be careful that ~3 different revisions of Quartet were released; SHA256 of the ROM we used: dcf0199e5fbc40cdf06131c376f821f275c3d518608de04ce1cfbe4d47c472aa.

RGBDS v0.4.2 must be used.

Then run make.

Notes

All symbols RE'd from the ROM (see quartet.sym) are available in the code, prefixed with Q_, and with dots replaced with _.

Text printing

E.g. Q_PrintStringCentered. Params:

  • Call Q_UnpackFont first
  • Make sure clear stack area (used as a buffer)
  • Clear D700 as well
  • Params:
    • hl = Tiles addr (tiles will be written to here)
    • de = Tilemap buf addr
    • bc = Input text
    • a = Row to XOR over all tiles
