I love my OSSC. It’s the best scaling device I’ve ever used and with all my other RGBS arcade boards it’s been flawless.
I read TMNT is supposed to be 288×224 @ 60Hz.
The board was sold as working “enough” to display an image (the seller has sent me video of it working), I just get a blank screen, on the OSSC LCD I just see it flick between 254p and 264p and say “NO SYNC”. When the LCD on the OSSC flicks I see 59.18Hz and 61.52Hz also. It stays at 15.62kHz
TMNT is connected to a Minigun then via to SCART to the OSSC AV1 RGBS. The Minigun has an LPF and I’ve tried it with it enabled and disabled. It’s RGBS that comes out of the Minigun, The red light on the OSSC is constantly lit and the “Info” button doesn’t do anything unless I hold it down and I think I can make out:
264P 456195 (maybe 456194 also)
Has anyone got an OSSC and TMNT setup, or even a another TMNT hardware game:
Crazy Cop / Gang Busters
Devastators / Garuka
M.I.A. / Missing In Action
S.P.Y. / Special Project Y
The Main Event
Thunder Cross 2
Did you have to tweak anything on the OSSC?
I have no idea where to start, there are a scary amount of settings in there?
Poorly designed Superguns are the number 1 cause of damage to OSSC units. I have no experience with that Supergun but you would need to check that it is properly attenuating sync from your arcade hardware to 75ohm.
Sync opt section is where you want to go. But even better if you can scope the sync levels to get some idea of where to begin tweaking. Most importantly the sync levels should not exceed 0.7Vp-p under load (someone please correct me if i’m wrong), when connected to AV1.
