I’ve launched Atomiswave in 31 kHz via GBS8220 then AV3 from OSSC, and it has worked fine !

I’ve succeeded in getting Sega System 24 running as well.

I still have sync issues with Sega Mega Play, it’s more stable now, but sometimes the sync is lost.

About CXA1145P pin 20 (C-video out) to DIN 8 connector pin 3 and DIN 8 connector pin 3 to SCART pin 20, the multimeter doesn’t ring. The wiring is not direct, but it should be something like that.

I’ve traced the path between JAMMA pin P (video sync) and the output of the RGB connector (I’ve tried all the pins) and the multimeter hasn’t rung.
Btw, I use an official RGB cable from PAL MD1 with the small board, which has the same pinout than Vega Jr. RGB connector :

Atomiswave mobo is working, I’ve tested it in the cab as well. I think I’ve to edit something in OSSC settings.

I was surprised as well about LM1881, but it hasn’t. I’ve written what the guy said on the Web before checking.

I believed Sega Mega Play was like an MD, but MD profiles didn’t help at all.

I’ve tried Atomiswave via JAMMA port in 15 kHz (not in VGA).

Banpresto PCB (Denjin Makai 2)


Sega System 18

Sega Mega Play still has sync issue and AtomisWave doesn’t sync at all.

I’ve updated to Beta fw 1.06a marqs, now everything looks OK, but there’s no sync when I try to launch a board with the supergun.
Is there something to do to autosync ?

Vega Jr. supergun has Mean Well MWP-602 110V/220V switchable PSU, like Sigma Raijin and Hakuryu. I only have to set/check +5V (between 4.8V and 5.15V) when I want to play.

It could be a good idea and may fix the sync issue, but I don’t know if a micro SD card with less than 1 GB storage is enough to update to your “Beta” fw.

I only have a small micro SD card I formerly used with a linker for N3DS.

The sync is still instable when I try to play or insert coin and always change from :
AV1-RGBS 262-P
15.69 kHz 59.91 Hz

to :

AV1-RGBS
NO SYNC

I use a Vega Jr. supergun. Gonna try to change PLL coast values to 4 and post the result.

I’d like to know if someone tried to use Sega Mega Play (arcade hardware) with an OSSC.
In fact, I use a RGB SCART from my supergun (Sega Genesis compatible), I let OSSC default profile, I turn “Allow TVP HPLL2x” option to Off, I move “Analog sync Vyh” option to 146 mV to get something displayed, but it’s still instable.
