Board revisions
Board Revisions
Over its production run the N64 went through several internal motherboard revisions. For flashcart and import purposes these differences are minor, but it helps to know what they affect.
What changed between revisions
- Component consolidation: later boards combined chips and simplified the layout to reduce manufacturing cost. Functionality stayed the same.
- Video output circuitry: some revisions differ in their analog video sections, which matters mostly to people installing RGB or other video mods, not to flashcart users.
- Regional boards: NTSC and PAL boards differ in their PIF/CIC lockout configuration and clock timing, which is exactly why PAL imports need extra hardware.
| Concern | Does board revision matter? |
|---|---|
| Running a flashcart | No, all revisions work |
| Backing up saves | No |
| RGB / video modding | Yes, revision affects the approach |
| Region behaviour | Yes, NTSC vs PAL boards differ |
Practical takeaway
For everything covered in this wiki, the only board distinction that affects you is NTSC versus PAL. Minor revision numbers within the same region make no difference to flashcart compatibility.
