Hanabi de Doon! Don-chan Puzzle Retail N64 Hack

This series of patches allow a retail N64 console to run the various Aleck64 title. It mimics the hardware registers used for the DIP and hardware switches and pushes N64 controller output to the joystick registers. The bootstrap has one additional opcode to pass the correct seed byte. You’ll need an 8MB expansion pak, and optionally a 4K or 16K eeprom to save settings and scores.

As of version 1.1, standalone patches were abandoned in favor of an autopatcher. This requires either 64bit Windows or something compatible. You’ll need to provide both ua3003-all01.u3 and ua3003-alh01.u4. (MAME’s filenames in doncdoon correspond to these two ICs.) Although these two files are natively little endian, the patcher accepts either byteorder. They will be tested against known good SHA512s. Incorrect or bad files will display an error. Select any applicable DIP switches, then output an N64-compatible ROM usable on hardware. Output is native byteorder (big endian), using a 5101 CIC.
