Hello, I'm having video artifacts on some games, here is a little bit of the history:
Sometime ago (before I've learned that they're bad) I bought one of those cheap Aliexpress knockoffs.
BIG mistake!
I played it a lot, them after I found it could kill my console I retired it.
I played other games, but this one was the only one with a 3v IC (MSP55LV160A) and no level shifter only a diode on the +5v.
Recently I saw a flashing background on Super Turrican and some artifacts on the Donkey Kong 2's 1st stage.
After I ran the SNES Burn-in test, I discovered it fails the DIV 16/8 test.
AFAIK, this failure is related to the S-CPU.
Now, the questions:
Would this cheap knockoff be THE responsible for this failure?
Could this problem be caused by some broken track or other component? Or is it internal to the CPU?
Is there a good place I can buy these parts? I could get some old SNES boards, but I'm not sure if the CPU of any of them is fine.
Can this failing function be rebuilt with a circuit made of discrete logic ICs? I really think not, but I'm asking anyway... Maybe with an FPGA...
Thanks in advance.
