Hello, I was cleaning up and testing some old Playstation consoles. This one I tested would boot backups but would not boot retail games.
I decided to open it and have a look at the chip. When I saw it, the soldering looked bad and the board was very dirty.
I began cleaning the board with some Isopropanol Alcohol and an a toothbrush. As I was cleaning a couple of wires popped off the board so I imagine they were very old and cold joints. I fully de-soldered the chip and cleaned the board completely.
While the board was in this state I reassembled and tested a retail game again and it booted straight away.
Then I re-soldered in the chip, with much shorter wire runs and overall tidier than before.
And again on re-assembly it will boot backup's but not retail games. This time I tested with a retail version of Final Fantasy IV NTSC, and it did not boot. I then put the disk in my PC and used Imgburn to make a bin/cue, Burning this the game boots fine as a backup.
Does anyone have any idea,
What this chip is?
Why it's not booting retail games?
Is it missing some connections?
and is there anything I can do with it to get it working properly other than buying some blank pic's and burning a mm3?
Thanks in adavance
