    • Looking for assistance on JAMMA PCB Arcade 1up conversion

      New

      I have a Namco System 12 board for the game Ehrgeiz. I have a Street Fighter II Arcade 1up cabinet. My goal is to be able to use the Ehrgeiz PCB on the Arcade 1up machine. I've seen people use the 60 in 1 JAMMAs but with the vertical machines. I'm not entirely sure if I have everything I need:

      Everything below is what I have so far:
      amazon.com/gp/product/B007TUSX…tle_o05_s00?ie=UTF8&psc=1
      amazon.com/gp/product/B07DCPT1…tle_o05_s00?ie=UTF8&psc=1
      amazon.com/gp/product/B07H7GF3…tle_o07_s00?ie=UTF8&psc=1
      amazon.com/gp/product/B06X9NJ2…tle_o00_s00?ie=UTF8&psc=1

      I'd also like to get this switcher in case I want more JAMMA boards: ebay.com/itm/6Way-6in1-Jamma-A…d869a9:g:HF0AAOSwsndbX13u

      I was also planning on buying this to help me out: amazon.com/gp/product/B07D7HQM…smid=A14L2IPQKNJPJ2&psc=1

      Is that pretty much everything I need? I've never done this before so any help would be super amazing.

      I cannot speak to converting your arcade1up cab to jamma. Maybe you’re following a guide somewhere? I see kits online which might be easier: diyretroarcade.com/index.php/6…up-vertical-machines.html

      Your parts list doesn’t seem to have a jamma harness. I’d also question that power supply. I’d also question that lcd driver but hey... we do mostly the original hardware side here ;)

      But when you do get that all sorted, you’ll be plugging in a pcb that requires a kick harness. Here’s the manual with the pinout.

      gallopingghostarcade.com/qr/ehrgeiz/manual.pdf

      Just one piece of the puzzle but one you weren’t thinking about. You could maybe make one, or @XianXi makes a namco to cps2 adapter (jamma-nation-x.com/jammax/store.html) at which point there are a lot of cps2 kick harnesses out there you could wire directly to the kick buttons.

      Unfortunately, the diyarcade link you sent me is for vertical machines and not horizontal. I'm trying to follow guides but I've been having issues because people either drop them or go with a vertical machine.

      amazon.com/gp/product/B07D7HQM…smid=A14L2IPQKNJPJ2&psc=1 This one doesn't have the right JAMMA harness? This link also has a power supply.

      I selected that LCD driver because it fits the LCD model of the cabinet. Is there a type I should be looking for instead?

      What's the kick harness used for?

      Dude, why are you buying a cheap crappy cabinet, with cheap chinese parts, then spending a ton of money and putting in more cheap chinese parts in it?

      What is your goal?

      If it's to have the arcade experience at home, hunt down a used JAMMA cabinet, clean it up, and plug in your JAMMA games (one at a time) into it. The JAMMA switcher is a waste of money too.

      If you want to just keep that small tiny cab, then honestly, slap a RPi into it and call it a day, you'll get the most bang for your buck. If you want better emulation than the RPi, then get a small MAME computer.

      Trying to jam real JAMMA PCBs into that cabinet will waste a lot of your time and money and you'll never get a good result out of it.

      Ok must have missed that link. Looks good, psu and harness.

      I couldn’t tell you about the lcd driver honestly. Just running an lcd will introduce lag, so a lot of us would use an OSSC to scale the image to hdmi. Maybe someone here has done a conversion? I’ll let them talk about that part.

      The kick harness is for the kick buttons. Jamma as a standard only uses 3 buttons, the punches in a 6 button fighter. so the other three (kicks) are separate. If you plugged ergheiz into a jamma harness you’d only be able to punch. Look at the manual and you’ll see which buttons are on the jamma side and which ones come from that separate connector.

      Well I have the SF II cab already. The original plan for it was to convert it for RetroPie usage. However, I got a hold of the Ehrgeiz PCB so I'd like to try a build with that. The game, Ehrgeiz, does not play very well at all on MAME so that's another part of it. I'm not going to play the game hardcore so I'm not worried about input lag or authenticity. Also, my apartment is small and I cannot get a real cabinet up the stairs.

      The person I got it from told me he modded the PCB board with the following: " I just wired the pins on the board (kick harness connector side) to be compatible for the 4th button per player 1, player 2 per jamma standard. " With that information, does that change anything?

      Because it's clear he's excited about getting into JAMMA gaming and it doesn't make sense to buy cheap chinese buttons (from his link) to replace his cheap chinese buttons. I mean, why?

      As to the rest of it, again, I wrote it above, he will get a much better experience grabbing a used JAMMA cab to use, and it may end up cost just a little bit more in total cost.

      If he just wants to use the A1UP cab, then RPi it or MAME and save the money, with those cheap components and buttons, and LCD, it will look and feel just as good to him, give him access to 4,000 games, and save him a TON of money.

      Turning the A1UP into a JAMMA cab just doesn't make sense.
    • New

      Based on your recent post, just understand that Ehrgeiz on MAME (with a PC) is totally different than Ehrgeiz on a RPi, which uses a super old version of MAME, and is super underpowered.

      That being said, honestly, I'd say RPi the A1UP cab, and grab a supergun like the Home Arcade System (HAS) to play your few JAMMA games on your TV.

      If you are intent on turning your A1UP into a JAMMA cab, I can't really help, and people from A-P will likely help, but I'd try more here:

      I forget if ergheiz is 4 or 6 buttons. If it’s only 4 then you’ll need to confirm that jamma harness runs all four buttons. Standard is 3. Some cabs wire 4 thought which may have suited his needs. The manual says it’s 6 buttons... do 5 and 6 not do anything? I own the damn game just don’t play it much ;)

      Given the parts list I don’t follow how you’ll take video from the jamma harness and feed it into the lcd board. What’s that plan?

      I think ergheiz has vga out so you could run video directly. But for normal jamma stuff (like on the switcher) you’d need to solve that

      @xtrasmiley

      Rpi has a decent compatibility with mame2003plus which is an updated mame2003 romset from 2018.

      The problem with recent Mame is it relies too much on power hungry cpu / ram which arm android can't give.

      However some guys are maintaining mame2003 today for this reason, because it's more power efficient.

      You should check this romset version to see what updates are being done, some roms can work better than the old 2003 romset since it's being adapted with today's evolutions.

      @archimage I don't want to shit up this thread talking about crappy RPi emulation, so please start a new thread or PM me to discuss, but I think you are incorrect, from Mame2003 Plus' own description, it is using a VERY old version of MAME (from way back in the year 2003 in fact).

      "mame2003-plus is built on the same codebase as MAME 0.78, meaning that 95% or more of MAME 0.78 romsets will work as-is in mame2003-plus, where they immediately benefit from its bugfixes and other improvements."

      EDIT: I'll add that it seems like they are adding some newer games to it, but at the end of the day, it's a Frankenstein version of a 15 year old MAME build. Better to just buy a nice mini-PC and get full power, no?

      @xtrasmiley I've just said the exact same thing (except the fact that it's crappy. IMHO it's not true).

      Mame2003plus is Mame2003 updated lately in 2018. with fixes, newer games from the newest releases.

      This is derailing yes but the extra information about Mame2003Plus could be useful to anyone since you mentionned that the romset is old, yes I was thinking it's old and obsolete, but that's not completely true, since it's maintained nowadays for the reason I described. Some people may find this information useful when looking for compatibility.

      Rpi is still a valid solution for the budget/size, and it's evolving pretty well, framedelay and runahead can be quite impressive, I expect some good evolutions with RPI4 if the devs use it's horsepower.

      People who want to use Rpi would check which games are 100% covered, lot work 100% and could be enough for them for a lifetime of playing.

      If you want bleeding edge go for a pc yes, Rpi will never catch Mame 0.200 since it's optimized only for PC but that's up to your objectives, which games you want to play.

      Let's close this detailing yes.

      I don't know about arcade 1up, but bascially for any setup if you want to do play with real pcb with jamma you need a supergun + a scaler to fit the resolution of the lcd screen correctly. Check the specs of the screen, the kind of input it's using, you could want to replace it with a better screen if it has lag, it's up to your ambitions.

      That's why it's the question was asked, is it worth investing so much in such a cheap cabinet ?

      If you are happy with the cabinet why not, but if you want to be as close possible as the real deal, it's pretty expensive to play on lcd with old hardware, that's why an old school jamma + crt cabinet could be closer to an authentic experience with less expenses, and an emulation solution more bang for the buck according to the specs of the screen if it's low end not worth looking for the high end setup for the source.

      Some people would also tell you that crt cabs could be expensive to maintain.

      Best thing is to count how much it would cost you from the system to the screen and decide by yourself if the arcade1up cab is really saving money and space compared to a purchasing a cab.

      Ok just looked on mine. It’s also wired for four buttons so you can run them all through the jamma harness. No kick harness required.

      Video can go out the vga and into your lcd driver. In the service mode under Display Test you can toggle between interlaced and non-interlaced. Obviously you want non-interlaced.

      Run stereo out of the rca jacks on the pcb, or mono via the jamma harness.

      Power into the pcb comes via the psu you linked, through the jamma harness. You want to measure just over 5v (like 5.07) on the 5v lines with a multimeter. the psu will be adjustable, so you adjust it for each pcb.

      Inputs will connect via the jamma harness to the buttons. If that harness doesn’t have a button 4 you’ll need to add one for each player.

      For actual jamma you need to run video through the harness as well. Couple options but you are trying to get 15khz video at arcade voltages down to something your lcd can accept, like vga. One option everyone loves to hate is the gonbes focusattack.com/gonbes-gbs-822…-arcade-hd-converter-pcb/

      If you get more into actual pcbs you’ll find this thing sucks. It doesn’t handle the variety of sync rates or resolutions that arcade boards come in, but it would be fine to start.

      Maybe a more flexible long term approach is to stuff a supergun and OSSC inside the cab to handle everything. More work, different approach, probably better results but you may be working with a slow/laggy lcd anyway and that might be overkill.

      But you can omit all this video decision making completely for just Ergheiz because it has vga out, itself. Vga to that lcd card you had, should work.

      Ehrgeiz is the only PCB I have right now. I'm thinking about getting the Soulcalibur PCB too since it's one of my favorites and is also part of the same family of system via the Namco System 12. So I could very well do that for now.
