Messiah 2 Prob ... boots PS1 but no PS2
Messiah 2 Prob ... boots PS1 but no PS2 –
I've done searches and checked the faq, but I haven't found anything that addresses this specific problem. Can anyone suggest something to try? I've booted PS1 backups and originals no problem in both a V6 and a V7 that I've modded with Messiah 2s, but neither will work with PS2 backups or originals, on CDR or DVD. Neither work.
Any suggestions? I've gone over all points, tried installing and reinstalling the chips, and every time it'll boot PS1 games but no PS2. Trying with a V4 now but sadly am expecting the same results. Also, I've noticed that some of the PS2 menu animations are a bit slow and choppy.
The FAQ addresses this problem with this text:
PS2 backups/imports (CD-R/DVD-R) won't boot or Red Screen Displays
Disk was seen (groove found & focused) but PS2 was unable to identify it as valid disk type (Audio/DVD/PS1/PS2). Note that if the groove had not been found, the Browser would have displayed No Data.
If it's all backups that wonÂ¡Â¦t boot, first suspect is B C, then try cleaning the laser lens with a cleaning CD. If itÂ¡Â¦s just DVD-Rs that won't boot, suspect wires E, R, W or the DVD laser diode (which may need recalibration). Laser Azimuth might also need adjusting.
Then suspect a loose wire, solder bridges or solder balls. If you can't see bridges/balls, then it's the hard way. If the BIOS wires are attached, detach them from the BIOS & clean up. Boot a backup using AR2/GS2. If it works, A-I are OK; the BIOS was the problem. (You can try this with the BIOS wires still attached but if it doesn't work, you'll have to take the BIOS wires off).
When you can boot backups (including DVD-R) with AR2/GS2, carefully re-attach the BIOS wires, MNOP QTUV RW. Note that R and/or W may be located off the BIOS chip on certain PS2 models. Then try direct booting of backups and/or imports.
You haven't described the failure symptoms so I can't comment further. No idea whether or not you go to Standby before booting PS2 games after PS1 mode. So we need more info as to what's going on.
Thanks for the reply, but that doesn't address my problem.
The PS2 can detect Audio CDs and PS1 discs, but not PS2 CDRs or DVDs. I've yet to find any example in any post or faq which specifically addresses OK boots of Audio CDs and PS1 discs, but nothing else.
Disk was seen (groove found & focused) but PS2 was unable to identify it as valid disk type (Audio/DVD/PS1/PS2).
You just quoted one sentence/symptom from the FAQ article. The rest of the FAQ might well apply even if you think your wiring was OK. Also you have not provided the additional info I requested. Are you going to do that or are we to be kept in the dark?
No idea whether or not you go to Standby before booting PS2 games after PS1 mode. What are the screen symptoms when the PS2 backups fail to load? What do you observe? So we need more info as to what's going on.
Okay, here's exactly what happens. I've installed a number of Messiah 2 USA chips which I ordered directly from http://www.mc-sales.biz/ the official supplier. V1.07 chips arrived a few days ago.
After install, only PS1 and audio cds would be detected. I'd never used standby to set PS1 mode, and haven't tried the reverse to set the chips back to PS2 mode ... I'm operating under the assumption that Messiah 2 chips default to PS2 mode once booted and will drop back to that if the power is disconnected.
I've noticed that drive speed has become irregular and makes awkward noises. The animated browser screen also appears to be still after it loads. The systems only recognize music and PSX backups, and when I put in DVD or CD PS2 originals, as well as DVD+R, -R, and CDR backups, it always drops back to the browser thinking that the discs are audio. Since these same things happen in three different PS2s, I'm assuming that it's not a laser calibration issue in every case ... especially since all of the PS2s were able to read and play burned DVD movies with no problems before. I've checked and rechecked all points with a magnifying glass and have been unable to find any bad solder point.
Thanks, I appreciate your help.
Ok that's a fairly comprehensive description. Here are several things to try:
- As these are 1.07 pcbs (when did you order them?), you should cut the track as per the picture in the troubleshooting guide. The Actel may need the correct voltage rather than the overvoltage.
- Check that the battery is connected
- Check that your wires are flat along the motherboatd and not pressed by the cage; also ensure the chip is not grounding.
I rather fancy the first suggestion because it was common to more than one install of the same chip.
Ordered them last week. Very strange that they'd send me old chips, but then again I'd paid for Fedex and they messed up and shipped regular post, then refused to refund only discount my next order.
Tut - you should have bought from me!
So had the track been cut? Have you done it now? Does it thus work?
Tracks have been cut.
Can't seem to get PS2 games to work at all.
Here's what happens:
Any time I put in a PS2 disc (backup or original) I'm kicked back to the browser screen with the message "Please insert a PS2 or PS1 disc."
Any time I put in a PS1 disc it boots immediately (without any boot trick or reset button hold).
I don't understand what could be causing this. Have you ever heard of just PS1 games booting, but not any PS2? How do I reset the chip to return it to PS2 mode?
I'm beginning to think this might be a bad version of the Messiah 2 bios, as it's permanently in PS1 mode.
Tried all of the instructions on the Messiah 2 website ... when I disable the chip, by putting in a PS2 original and holding reset for 5 seconds beyond the blue light, it also dumps back to the browser screen. So the only function that the Messiah 2 performs correctly is booting PS1 games (both originals and backups). Nothing else seems to work, and I can't find any solution which addresses this specific problem.
The tracks arrived cut. It's really odd.
