Guide Dreamcast, PS1, N64 Undervolting info (incomplete)

[Wesk]

Unlike the much more complete Wii undervolting "guide" this is just a smattering of info found when undervolting the DC, PS1 and N64.

Dreamcast info (8w to 5.5w)

N64 info (5w to 3.5w)

PS1 info (1.5w to 0.7w)

Like everything, use this info at your own risk and results will very likely vary from unit to unit.​

Just to add a couple notes for the N64:

- N64 wouldn't boot for me with Vterm below 1.9V, 2V has been solid.
- Boots fine and runs on 2.9V with occasional graphical glitches, but 3V has been solid.
- Expansion Pak adds about 0.6W additional @3V, may vary between more RAM intensive games.
- Power consumption was right in line with Wesk's numbers
- These tests were performed on a stock board with the 7805 reg removed as well as U3, will consume a little less power with the Video/Audio DACs removed

Runs a little cooler overall as one would expect with undervolting. These results may vary between boards.

Undervolting Vterm is basically pointless as it's such a small saving but figured I'd list it anyway.
