I am determined to repair them and get them working again.
Do you have and know how to use an oscilloscope?
From what I can see, you did a nice job non-destructively separating the boards which is often the deal-breaker for guys attempting to mess with the PS2 5V board set. But do you have a method to non-destructively remove the ~50 to ~100 pin surface-mounted digital IC chips of the complexity as found on the PCB? When my eyesight was better, I used Chip-Quik for this purpose.
I see this as a matter of principle. If looking at this from a business perspective - say from a tech who repairs train electronics for remuneration - then this is a no-win situation! But if it is a personal mission in life to be the go-to-guy for what might be THOUSANDS of dead PS2 5V boards sitting in boxes (or the landfill), then hurray for you and let the games begin! As I see it, the satisfaction of repairing something that has been written off as a lost cause is priceless.
There is some guy or guys on OGR that reverse engineered how sounds are stored in MTH PS2/3 engines. This allows him/them to replace the stock sounds with whatever one wants. I don't think any money changed hands and I've got to believe this was more than a weekend project!
One thing's for certain. OGR is the right place to undertake the journey.
