Hi I am having trouble getting PS2 backups to boot. I installed a Magic V on a brand new V9 unit. I have cleaned, resoldered, checked and rechecked bios pins for bridging. I am 99.999% certain that the bios is not my problem. I can see perfectly with a 10x mag glass. There is no bridging splattering, or balls
I was wondering what connections B through I do. It would be nice if someone knew exactly EACH wires function. They are on the back of the board and more difficult to solder and harder to check than the bios legs in my opinion. They may be the problem. Or they may have nothing to do with booting a ps2 backup and I can forget all about them
I saw a picture that gives an alternate location for these points on the front of the board on the chip that B & C go to on V7. They are twice as close together as the bios pins though. I was going to check continuity by holding one probe to the Magic chip on the correct pad and the other to the alternate location. Continuity would tell me that there was a successful connection. However many many many pins on these chips show continuity with various locations etc. so this idea won't work.
I don't know how else to reliably check these points B - I
The system plays movies, music, ps1 backups fine
It plays ps2 original games fine when chip is put to sleep
Regarding PSX backups. Do they only need the chip to have power/ground/scex/reset wires connected to work?
Do DVD-R movies or music discs use the chip in any way? If so, what connections are used
If I knew the answers to these I could eliminate certain wires, possibly many if them
Also, does anyone know if there is a problem with modchipca? I opened a ticket with them and have had no response, plus I ordered a couple chips on Monday and have not received them or an email yet. EVERY other time I've dealt with them I get an email with tracking # within an hour of placing an order and I ALWAYS have got my chips the next day. My open tickets are usually answered within a few hours also. Any news on them? Anybody?
Thanks much in advance
