Any chance rotation could make it into the DExx? That would make it a must-own for me.

I wanted to give this feature request a bump now that the OSSC Pro and DExx are around and have frame buffers. The ability to rotate the display 90 degrees clockwise or counterclockwise and scale to fit the display would be fantastic for driving vertical arcade games through a CRT or HDMI monitor that doesn’t allow for easy rotation.

RGB is shipping out a new HAS batch right now – I’ve seen posts about people receiving theirs. You should contact him to see where you are on the waiting list.

I believe both the HAS and Sentinel can output SCART RGB and VGA simultaneously with the latest designs.

[ShootTheCore]

The HAS is available – you just have to get on a waiting list for it. There’s also a new, inexpensive SuperGun called the Sentinel that’s coming out which ships with VGA output. Details here:

The Sigma AV7000 is also a great SuperGun, but you really need to use VGA instead of SCART to get the best sync with the Taito F3. I did a lot of back-and-forth with Marqs and other knowledgable people and ultimately using VGA was the best solution at the end.

[ShootTheCore]

What SuperGun are you using with your setup?

Ultimately, I was able to achieve a perfect sync with 5X upscaling on my Taito F3 and HAS SuperGun by using a VGA cable connection instead of SCART. The creator of the HAS has constructed a specific VGA output adapter specifically for use with the Taito F3. The VGA connection separates the horizontal and vertical sync signals so that the OSSC can lock on accurately. SCART mixes them.

Marqs, forgive my newbie-ness – I still have a lot to learn. Where do I sample the vblank from on the Taito F3 board?

Just wondering – is there any way to mod the F3 to clean up the output so it would work over OSSC SCART? For example, would your CPS2 Digital AV board wire into the F3?

Some people have recommended this other mod to me, but even though the directions specifically say it’s for the F3, I’m skeptical that it would work:

I recently picked up an oscilloscope and used it to take samples of my non-OSSC-syncing F3 board in case the output differs enough from marqs’s board to be useful. As a reminder, my symptoms are:

OSSC display: 261p, 15.44kHz, 59.18 Hz
After pressing Info on the remote, OSSC display: VMod: 256×240 LC: 162 VSM: 2
LED is Red with no output signal
The same board and SCART video cable syncs perfectly with the Framemeister, but I haven’t been able to get it to work on the OSSC even with changing the inputs, power cycling, and adjusting the H-PLL Pre-coast and Post-coast to 4.

Scope output with sync signal and red signal on the board’s gradient monitor test screen:

I’m going to try VGA instead of SCART next, but SCART sync would be preferred if it is possible.

[ShootTheCore]

FWIW, my Omega CMVS works with my OSSC perfectly. Are you using the SCART cable from ArcadeWorks or a different one? Also, have you tried setting H-PLL pre and post coast to 3 and the Hsync tolerance to 10us or higher?

[ShootTheCore]

I’ll see if I can land one of those SCART to VGA cables and try the Taito F3 again. Fingers crossed…

[ShootTheCore]

Huh, that’s really interesting Marqs. I’m surprised-I’ve tried three different Taito F3 boards on my setup with identical results-no sync with the OSSC, perfect effortless sync with the Framemeister. Maybe the SuperGun or SCART cable I’m using is a factor. Did you find that a sync stripper was necessary for an OSSC sync?

[ShootTheCore]

Exciting news indeed! Thank you for looking into it marqs.

[ShootTheCore]

Nope, no fix yet that I’m aware of. I’ve been retesting my F3 after every OSSC firmware update hoping that it’ll work, but no success yet. The F3 still syncs perfectly with my Framemeister. The F3 is the only device I keep the FM around for now-everything else I have works fine with the OSSC.

Try adjusting Output Options->Line 3X Mode. From the wiki:

Line3x mode
Controls the sampling and pixel clock multiplication mode for line3x.
Generic 16:9: Uses full horizontal sample rate without pixel multiplication, resulting to fully utilized 1280×720/864 output (16:9 aspect). Useful if connected to a CRT via DVI->VGA converter.
Generic 4:3: Uses 3/4 of full horizontal sample rate without pixel multiplication, resulting to 960×720/864 effective area of 1280×720/864 output (4:3 aspect). [default]
320×240 optim.: For advanced users only – requires clock and phase adjustments. Uses a sampling rate which matches the DAC rate of 426 dots per line used by some classic consoles (e.g. several PSX games) in 320×240 mode, resulting to pixel-perfect digitization. Output is pixel-multiplied by 3 in horizontal direction, resulting to 960×720 effective area of 1280×720 output. Note: If picture jitters when this mode is selected, adjust sampling phase until sweet spot is achieved.
256×240 optim.: For advanced users only – requires clock and phase adjustments. Uses a sampling rate which matches the DAC rate of 341 dots per line used by various classic consoles (e.g. NES, SNES) in 256×240 mode, resulting to pixel-perfect digitization. Output is pixel-multiplied in horizontal direction, resulting to 1024×720 or 768×720 (depending on 256×240 aspect setting) effective area of 1280×720 output. Note: If picture jitters when this mode is selected, adjust sampling phase until sweet spot is achieved.

I finally got around to testing my Taito F3 board with the old 0.69 firmware. No dice – it refuses to sync no matter how much I fiddle with the settings. I did have success getting Rastan and Heavy Unit to both sync with the 0.76 firmware after replacing the capacitors on both boards. I also recently acquired a Ninja Baseball Batman (Irem M92) board that refuses to sync with the OSSC but works fine with the Framemeister – I’ll try a recap on that one as well soon.

I’ll stick to using the Framemeister with the fussy arcade boards for now and use the OSSC for everything else. The OSSC looks so much better with the 5X 1600×1200 settings that I want to use it for everything! ^_^

[ShootTheCore]

Sure, I can do that. Which specific older firmwares should I try?
