Forgot I had Deoxit. Cleaned the edge connector. Joystick works fine. I can play. Green color is back, however now sprites are corrupt. I have yet to clean the chips yet.

I went into test mode. All ROMS test ok. Next screen shows colors. It's missing Green completely and one bar of blue. Next screen is control test. Players 1 and 2 do not move up, but other directions fine. Player 1 fire button doesn't work.

I bought an untested PCB online and I know untested means may not work. I wanted it because it's original I think. She powers on, sound seems to work. Game starts but I can't move up, or fire. Any ideas on what to look at? I'm using a MAS Supergun and everything works with other games fine...

I'm not sure it'll be any better, but I have a Retroscaler 2X coming in the mail. I bought it because it was cheap and why not. I figured don't spend a lot of money because I hope to get a CRT soon. I almost had a Sony 32" tube TV, but passed on it ultimately. For now I have a 24" LCD with a...

I'll open a joystick up soon.. the outside is DB25.. The whole unit is indeed in excellent condition, however during shipping there's slight damage to the top. A screw or something poking through. Here's a slightly blurry picture of the board inside and two pictures of the damage. There's...

Every photo looks clear to me. I did not post the close up of the board I talked about if that's what you were referring to. Someone asked what mine looked like so I posted picture. One of the chips is a hex inverter 74HC04N.. The Sony one is super faded and hard to get a clear picture of...

Attaching some pictures.. I tested video on my HDTV and it works! Obviously looks like crap. My TV stand doesn't allow me to rotate, so I can only see it horizontally.. so inserting a vertical game is sideways. Attached are an image of the back of the unit, the unit on my counter (upside down)...

I plugged in the supergun today. I tested voltage at the jamma connector and adjusted it.. I'm at +5.05, but the other is like -4.06 and +11.59 or something.. are those fine to leave or should I get a new power supply? I plugged in The Main Event PCB and got sound. I just have to wait a bit to...

Another question.. what relatively cheap item should I get to convert the video output? I'm guessing I will buy an LCD computer monitor of some sort. Should I go with any old monitor from Walmart or shall I get the Unico 26 inch 4:3 ratio? EDIT: I bought a 20" CRT with composite and SVIDEO...

I've never used a supergun before.. everything seems to be in excellent condition.. the fuse is good. Some questions? I haven't opened it up yet. I see composite video.. what's the round connector next to them? S Video? What kind of joysticks do they typically use? I would like to 3D print an...

I send him an email the end of this month the beginning of next month. He'll have more in stock. I would like to get my hands on one. This will be the last stock for 2024.

I mentioned above I have a KIC 045 DX coming in the mail. I just bought a MAS Systems SuperNova which appears to be in excellent condition. I'm not familiar with the rarity of these but people say there were only a thousand or so made and it's like a holy grail for a lot of people. I'm super...

Thanks. Works on my cell phone (Chrome) but not on my desktop (Chrome).

Awesome!

Soon as I get some money I plan on scanning every page in and making a PDF. I wonder what's the best device to do so, though.

I don't mind if the information is already out there. I wanted the book either way just to have. I paid a good penny for it. I know some places I can buy it cheaper, though. I found a copy for $50 and a better condition one for $70. What's interesting is the original book listed for 1000 yen in...

I'm in need of a Supergun to play a PCB I own.. and more in the future.. so I decided I'll start collecting Superguns just because I think they're cool. The first one I bought was a KIC 045 DX. It was super cheap on eBay, hasn't arrived at my house yet. I am doubting it works.. it's missing one...
