This is a modified version of MEGA65 Open ROMs (https://github.com/MEGA65/open-roms), forked at upstream commit ad178dbe4d48cd6a317737a8e0e7e662f7e33d32. Modified by Christian Werner, 2026-10-14, for the mc64 computers of arnitech, a set of Minecraft mods (https://git.susdog.de/chris/arnitech). The fork lives at https://git.susdog.de/chris/open-roms, branch mc64. Changes: - src/,,config_mc64.s: a new build configuration, copied from src/,,config_c64.s, with its own config ID ($6D), the brand "MC64", and BCD_SAFE_INTERRUPTS turned off. - Makefile: targets for that configuration, build/kernal_mc64.rom and build/basic_mc64.rom, made the same way as the c64 ones. - NOTICE: this file. The licence terms are unchanged; see LICENSE, COPYING, and COPYING.LESSER.
