I've never seen this whole package. But I have a lot of the sound amplifier PCB that's inside.

U$ 150 Outrun Philko Bootleg revised PCB Tested Working accompanies control harness

It's not an easy job. The chips are extremely fragile to heat, I tried to do a swap when I had 2 boards with different defects, and ended up with 2 boards with more defects. Next time I'm going to weld each leg one by one with the iron, no hot air on them.

I'm sinking into the same shit. I need a lot of video memories. But the value to import with 92% taxes is so high in the Communist Republic of Brazil that it is better to leave everything as it is, one game that is working and not fix the other until they are all defective.

Try removing your wires and just link IC33 to IC24 pad , as I did.

A good bath with paint thinner can work miracles, one of my PCBs only needed one bath. Your PCB in the photo is dirty and may be contaminated with acids from the capacitors, the acids are conductive and can cause errors in the game.

The wire in the back is to fix the broken trace near the right side of the super cap solder hole. If yours pcb trace is ok you dont need it. Yours pcb trace seems a bit rot, you should test continuity.

You should look on the CPU BOARD, ignore the EPROMs board. I suggest you remove the super capacitor and clean the area, as they leak and create problems.

you're confusing RAM with eprom As this accusing two faulty may not be the ram ,may be some buffer or addresser IC

After warming up for a few minutes, the new setup practically disappears with the interference in the image. I suspect it's the fault of the almost 30-year-old electrolytic capacitors, when they heat up they improve a bit.

Using a VGA on the input to move the GBS further away from the Model 2 seems to have helped a bit. The interference now comes and goes, it is no longer continuous. I'm going to make a extremely short and shielded adapter to connect the VGA cable to the filter board, the one I'm using has about...

Same prices, the taxes here are absurd.

Very expensive for Brazilians 92% tax :cursing: I think for me it's still worth trying to improve the old gbc control that I made with the 8200 + arduino

I built a GBS control with a GBS8200. For the common video games, I didn't have any problems, very clean image. But with the Sega Model 2 I'm getting image interference, horizontal waves the width of 1 finger. My test was done with a half-meter unshielded RGB cable from the model 2 to the GBS...

Memory test fail poligon memory and poligon fifo

Now I need to find some memories to repair 2 video PCBs And as I live in Brazil, I can't find it here. I have to find a very cheap place to buy because the import taxes of our communist government are 92% to import anything.
