There’s an article about this on Eurogamer currently.
This is an amazing thing you’re doing here. I hope you don’t get burned out on it.
I tried to give you and some other people shout outs in the interview, but I guess that’s not really the style of the article, so they didn’t make the cut 
You work on the faceplate is still very dear to me

Don’t even worry about it, mate, the faceplate was but a tiny part of it compared with the time and work you’ve put in. Congratulations on the article, you must be really chuffed. 
Undamned I read the article and learned a bit about cps2 and the significance of what you are doing. Keep up the amazing work, hopefully I’ll have enough in my ud-cps2 fund to shoot you a pm someday before you stop doing this.
I need one of these for Alpha 2, I just ordered the A+B board and was gonna do a super gun, but I’m thinking this is a better option.
Thanks!
Better go the supergun route. It is ulikely I will be building any new orders this year (huge backlog of old orders, not much time, etc.).

Thanks for the heads up.
Hey @undamned , did you ever release any additional info on your DC-DC converter that you mention in your first post? 
Are these still being looked at? I wouldn’t having something like this for my Supergun.
Hey, guys. I have not released any info on these, as I got way side-tracked w/ getting the decoders out there and available since that’s what most of the clamor was about. Just know that they only put out +5 and +12 volts. No -5V, so if you build them into a supergun which you wish to use a huge variety of boards on, chances are you are going to encounter a game that needs -5V for its audio amp or something. I’ll see about putting together a data sheet for them and making them available this year.

Email sent.
any issue with using PicoPSUs as a power source? that way, not only will you get -5V, you could possibly also get 3.3V for JVS gaming.
EDIT
Just re-looked, -5v isn’t available with the stock config, BUT that’s nothing a Negatronwon’t fix.
Ouch $20 to get -5V? I’d throw that on my board for $5, if I needed it, but I don’t.

I’ve used a PicoPSU to power a Naomi, and had no issues. I’m presuming I wouldn’t have any issues with one in a Supergun or consolized CPS2 either, but it’d probably be way more economical to wait for undamned to release his converter.
That’s ok, skip the -5V for now. Just give us the board with the +5V/+12V!
it seems that with the UD-USB, and this rumored DC-DC board, the only thing that’s missing is the RGB to HDMI scaler. I’ve found a few out there, but I don’t want to drop $40+ to be met with some pretty heinous frame lag issues. Maybe using a JROK would be best.
sorry, off topic, I know.
I would venture to say any $40 scaler is guaranteed to be rubbish. There are multiple scaler projects going on right now on a few forums which look very promising. Ballpark seems to be sub $100 for lag free (the output lines are being written while the input lines are being read, so no need for a frame buffer) scaling. Won’t have all the whizbang features and flexibility of an XRGB or other high end scaler, but if it fits the application, the performance should be amazing.

I just re-read the entire thread and realized that you’re not using HDMI.
smacks forehead
oops 
and I agree with you. I’ve worked with some real garbage in the past and I’m really leaning into getting a Framemeister (XRGB MINI) for use on HD screens.
Oh my HD TV since it has VGA input I went with a XRGB 2 Plus.
Only issue is the XRGB2 Plus only does 640x480 VGA, but my TV has a good DAC so any effect from upscaling is not noticed.
once im back from japan I’m definitely purchasing one… and courtesy of my xrgb mini… I look forward to playing my copies of X-men vs sf , ST and alien vs predator on my setup
