testing along the way –
say i wanted to put a chip in and test it along the way, where should i start? what should i save till the end?
i was thinking of doing all the points except for the bios and cd/dvd controller, then test it, if all goes well, then the bios and so on.
You used to be able to do that with Messiah 1 but Messiah 2 requires the BIOS wires to be attached for all functions.With Magic 2 (so maybe Magic 3) as well as Messiah 1, you could attach Power, Ground, SCEx, Reset and test the PS1 backup function. You could then add the BIOS wires and boot backups behind AR2/GS2; then add the CD/DVD Controller points and boot no-swap. Some chips may do this now, but I doubt it and you'll get confused when things don't work.
is there any testing you could do for messiah 2?
i was thinking this would help, cause if i can get so far, and then after the next step something goes wrong, i know where the problem is.

well, im starting to re-install (after 1 failed attempt and a lot of headache trying to get the thing working again) an apple pro into a v7. so far got everything but bios and controller on the back, ill see what it does. too bad i dont have a AR/GS to test the bios wires.
I think you can attach all but CD/DVD wires and boot a backup with AR2. Don't count on it though - just trying to remember from a year ago.
well ya, ps1 method works. wasnt able to try out AR/GS with a ps2 game cause i dont have one.
anyways, worked on 2 of my friends ps2's (both v7's with apple pro's), got them both to work after a try or 2. (i always save +5v for last, but i happened to miss it on both systems )
now i gotta fix my friends that is broken.
