Having an arcade game collection is the dream of many, but the full-sized machines take up tons of room. Why not play the original PCBs instead! Info on choosing a JAMMA SuperGun, RGB video transcoders, input options, interface adapters, ROM swaps and more

For convenience, I got a Sega Naomi cab a few years ago, it's already a computer setup in a sense, the screen is a Sanyo 39- semi flat in 31KHz with VGA connector input, I bought a trifreq chassis and a converter for the controls (the cab got a proprietary centralized controls box that regroup all the player 1 and 2 commands, 2 starts buttons and coin box controls, but connect to the Naomi system with a USB-B connector, the converter simply make the controls signals recognized as a keyboard. It works great in emulation. I planned to add JAMMA compatibility, coupled with the trifreq chassis, there will be almost no need for a video converter, only a cable converter, same for the controls going to the JAMMA connector. The cab itself is a hard piece of metal, very sturdy, the plastics are essentially here to decorate (except the control panel, it's made of plastic.
The plus side are: the Naomi cab is incredibly cheap, got mine for less than 300- in OK condition (totally functional, in need of a good refresh cosmetically, it's sturdy, the system is easily hackable to accept many cab systems (either single board, central systems with carts or a PC motherboard for emulation.
The downside are: it's heavy, 130kg of pure Japanese goodness (even if the cab is mounted on wheels, I don't move it frequently. the screen is a CRT, with all the problems that occurs with them (on the good side, a couple of years ago, I found that replacements are still sold for not that much, but still an investment and flat screens conversion kits exists as a last resort. The screen needs a VERY specific resolution, there's some solutions, either hack the video card to spit the good resolution from the PC powering up or adjusting the parameters of the driver, but it require to wait for windows to finish the booting before power on the screen.
That said, possessing a cab at home is just fantastic, playing at old arcade classics on the hardware with friends is pleasant (even if it's not the original hardware, it's still arcade tech) and it's a good looking piece in my living room: )

I just use external scanline generator with my mame pluss. 122 with pc crt, perfect refresh matched, perfect shading, blending, scaling, prescale the pixels to scan line, resale the pixels 2nd time with filter, turn of screen streching, stretching, let it scale its self for pixels perfect. prerender frames to get perfect animations that people skip on in emulators. Than I have a second prerendering for higher prerendering. I over clock some games virtual cpus that mame uses to gov your pc cpu to games speed but games can stutter so you over clock game with out speeding it up like double dragon slowdowns. i have videos on how to do it. its an art firm on getting pixels back, and pixels shaded nicsley. i use bright ness to clean up rest. darker back ground with light in right places. None this bright over situated crap like I see on most emu labors and arcade cabs. you want to make 2d look 3d to pop out screen. That is how I have mine. Contrast plays part also on hiding jags, defects.

Dear Sir I speaking from Bangladesh. I am a arcade gaming business man. I have a couple of video game shop in my city. My gamer is fell bore to play of pandora or those similar game. So I need to some new multi game with jamma pcb accordingly. In fact neo geo, capcom, konami or other jamma pcb platform has not attract the new generation gamer. So i need a new gaming jamma pcb board like Fifa 11, 12 or 13, need for speed underground, tekken 6 or 7, house of dead 2, call of duty like others.

I'm trying to get this to work, and I think I have everything set up but the power supply. I'm trying to get Pac-Man to work which needs -5V but I can't find a new ATX power supply to do the job. I bought the Essentials Basic and I already had the Suzo Happ from another project so I figured I'd just hook it up. The problem is how do I connect the Basic to the power supply? I don't have any obvious terminals and I'm unsure how to connect them. Is there yet another converter I could get to alleviate this issue? Either an ATX with a -5v or a way to connect my Suzu Happ to the ATX would be much appriciated.

13: 30 >Fair enough and each to theirs but with all those nice CRTs you have I'd find it impossible to be satisfied and enjoy playing on LCD, trying to go back to the terrible lag and motion blur even the top end LCDs have just sucks hardcore, not to mention the picture IQ and blacks on LCD being abysmal compared to a good CRT. If I didn't have access to a CRT (or at least a good plasma like an 8/9th gen Pioneer Kuro, those have fantastic motion clarity plus all the rest like IQ/blacks/response/etc, I just wouldn't bother playing a game, or maybe I'd just use a handheld instead or watch a movie.

I wonder why the Americans only had component and we over here in Europe only had RGB/SCART?
I'm guessing it's because over in Europe, we had more than one colour standard. Some countries used PAL and some countries used SECAM (and Belgium used both, PAL in Flanders and Flemish language networks and SECAM in Wallonia and French language networks) and America only used one colour standard (NTSC)
RGB is colour standard independent, component (and composite) isn't.

How much did these boards cost arcade owners back in the day? I imagine that they were much more expensive than what they cost today. (Discounting the cost of the converter train)
Also I love that people are picking up the new timestamp feature to create chapters in their videos. It is such a small change and a decades old idea, but it is still great. Hierarchical chapters as found in MKV never picked up steam, but perhaps one day.

I'll admit dealing with retro video game video output can be a chore. The OSSC has it -mostly- solved but it can get temperamental if the game decides to switch up resolutions. The OSSC generic mode is good about dealing with that but you don't get the crispy fine-tuning that comes with using OSSC profiles.
If I didn't get an OSSC I'd probably think about getting a GBS-C AIO instead. That seems easier to work with.

It's not easy. It's a giant money pit. I have so many regrets about getting into collecting arcade games, it's not even funny. And things will break down and have to be cleaned out. Pins will break. batteries will suicide and caps will go bad. If that's not enough the super guns alone can be finicky and expensive. You're better off sticking with emulation and saving the money to be honest.

How much of a pain in the ass would it be to set this up for some light gun games like Area 51, Target Terror, Police Trainer, etc? I would like to build a multicab, but I just don't have that kind of room. I want to set up a few PCBs in a big wooden box with everything contained that I could just plug into a CRT monitor/tv, but I don't think it's going to be that simple.
