What's new
Hello everyone,

I have a quick question, my setup consists of the De10 nano and jpac2 on my vewlix Diamond black.

Im wondering what are the best settings for the video area on the mister like the resolution i should have it on. I have the stock 1080p monitor.

Here are my current settings which im sure are wrong.

If anyone can take a look i would appreciate it.

Small update, assembly factory shifted completion from early December to before December 15th, I still have a small hope to get this batch out this year.

"Intention to purchase" list is closed, and will announce here and on twitter when they are available for purchase for those not on the list.

Chip & parts shortage makes a potential 3rd batch very uncertain, market is vacuumed for parts and has been for quite some time.

Updated firmware - addresses the issue some people had with (out-of-spec) voltages in cabs, and ability to change sync-guard. Some of the sync-guard options may not be super useful right now, but may be to some people in the future, default is 15kHz/JAMMA.
  • 15kHz/JAMMA
  • 15/25 Auto *
  • 25 kHz/EGA *
  • 31 kHz/VGA *
  • Tri-Sync
  • Off

I plan on shipping the units I just got with this release, so would be great if someone could give it a spin.
 
My expander is working perfectly fine, really love how easy it was to get it going. The hardest part was getting the OS and software installed. Bending the HDMI cable was a little scary, wondering if there's a right angle option or something that maybe we can utilize to help with connector strain.

I'll update the firmware and give it a go! If I run into problems I'll know right away, but I don't expect any. :)
 
Ran into an issue with the expander- I'm not able to configure directionals. For games like Pac Man, Pengo, - you have to program all the buttons. I'm able to go through the motions and program them, but when I go back into the game the directionals don't work. Coin/start/shoot work after programing, but the joystick does not. Help?!

Did you try gamepad mode?
 
Hey, I haven't. I can try that next, but since these were arcade cores I thought game pad mode was for consoles. So some arcade cores will only work with game pad Mode?
 
I received mine a few days ago and put it together yesterday. No matter what the voltage is on my Blast the synch guard is on and I get no image. Any ideas? I've adjusted the composite_sync and direct_video as well. Kinda stumped

Navigate to the video info screen on the OLED, it will show frequency and lines and may give a hint.

I've messes with the oled messages and nothing renders an image.
It's also worth to note that it doesn't save any settings, gives me a SAVE FAIL message. Not sure if anyone else has used a Blast with this. My mistercade works fine.

Check troubleshooting video, end of page.
You need an sd-card in the expander to save config.
