README
README.mdUltraCIC-III
This code allows you to create a replacement CIC chip for N64 games that you own on an ATTiny25, ATTiny45 of ATTiny85. The original code was written by jesgdev and updated with multi-region support by saturnu. I simply extended the version Krikzz created under the name UltraCIC-II to support automatic switching between NTSC and PAL if the console was unable to boot.
Instructions
- Install avra
- Assemble the code
- avra UltraCIC-III.asm -d {MCU}
- {MCU} must be one of the supported MCUs (attiny25, attiny45 or attiny85)
- Flash the file to your ATTiny
- e.g.: "avrdude -p t25 -c usbtiny -U flash:w:UltraCIC-III.hex eeprom:w:UltraCIC-III.hex.eep" for attiny25
- Update fuses
- e.g.: "avrdude -p t25 -c usbtiny -U lfuse:w:0xc0:m -U hfuse:w:0xdf:m" for attiny25

Questions
How big is the UltraCIC III PCB?
It measures 10.7 × 20.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UltraCIC III use?
4 parts, built around the ATTINY25-20PU and ATTINY25-20SH. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the UltraCIC III KiCad files?
From the ManCloud/UltraCIC-III repository on GitHub, at the commit this page was made from: the board is pcb/UltraCIC-III.kicad_pcb and its schematic pcb/UltraCIC-III.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UltraCIC III design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
