The board was working when I did the installation, no issues with battery.
I'll try all the SZ2 codes in order to check if some of that works, I hope to revive the board. I also bought yesterday a eprom reader but it'll arrive in one month.
Ok, if game was working with battery, that's a good starting point. Yeah, try all SZ2 codes.
Also, my board is 4 version but I tested closing the pin because on the youtube video it said that is not mandatory. @undammed, is it mandatory to do this??
Your board is a -4 so you need to close the jumper that says “leave open for -5” and connect your power and ground
Rev. 5 Jumper does not matter on Rev 3/4 installation. It doesn't hurt open or shorted. There is only so much room for text on PCB, so that is simplest/safest text
Antother question, for the other cps2 board(sfa usa-version), I had revived it but the game is working shown all in the video on green. I removed the resistor, as the video said(youtube installation), this can cause the issue?
Also, the board was dead when I did the procedure, the person that sold the board said that the game was working well until the battery was changed incorrectly.
When you say "video on green," do you mean that game is running fine, but picture looks very green?-ud
