I have a Stargate machine that has been giving me fits since I bought it a year ago. Although it was fine when I bought it, most of this past year it has not worked 100% for various reasons.
Right now, it's giving me a 1-2-1 error code when I turn it on. It shows the multi-color pixel screen which is normal, then it kind of hangs, sometimes staying on the same screen, sometimes going to a screen that looks like the game is running, but the video is all garbled. None of the buttons work, so it's pretty much dead at that point.
I understand the code 1-2-1 means, ram error, bank 2, chip 1. I have pulled that chip out, replaced it with another from a different location, and same error. They only way I can get it to give me a different error is if I pull the chip from bank 3, chip 1, which I understand is the first chip tested, then I get 1-3-1.
I'm pretty much fed up with this, I didn't buy this thing to take up space in my rec room, I'm not playing it. I really don't want to sink more money into it, having it repaired by a onsite technician $$$$, so I'm thinking about just gutting it, selling off the boards and turning it into a multi-mame machine that plays Stargate and others.
I hate to destroy an original stargate arcade machine though.
I have a Ms Pacman that I restored using mame, but I bought that as a non-working empty cabinet, so I didn't feel so bad.
Any suggestions?
