Tate mode rotation

[leewrigley]

Hi guys,

So as many of you know many shooters (mainly ps1/Saturn era and above) have the option for the games to be played in their original arcade resolution and vertical orientation. The problem with this however is that when playing these games in Yoko mode (horizontal) the resolution is somewhere along the lines of 180x240p with black bars on either side. The original arcade resolutions are closer to 320x240p I believe which means missing out on a lot of resolution.

I was reading up on this website which j will link below for anybody who wants a more detailed explanation than i can provide. But this guy basically used a special card to rotate the Tate games back to a Yoko orientation whilst maintaining the higher resolution to display on a standard display.

Now what I wonder is that with a piece of hardware like the ossc could something as simple as a 90 degree rotation be possible. This would be a really nice feature if an implementation could be done. Any further insight to this would be awesome or if anybody knows of some kind of device that could do this on its own that would also be awesome. Thanks guys

Not possible without frame buffer, so the OSSC cannot do it.

[leewrigley]

So is a frame buffer not something that’s possible on the current ossc hardware then? Obviously it would add lag but it’s not something I would particularly mind

Yeah the OSSC is a line multiplier not a scaler, it does not have a frame buffer. There’s definitely a gap in the market for something that can do this easily and well, even high end solutions like the Datapath x4 aren’t particularly good for this and require a lot of fiddling about.

Bucko, is this something that can be worked into the OSSC 2? I mean, obviously it adds lag, but I think the community could definitely use a sequel to the OSSC and the Frameister that has these types of features.

Are there even plans for an OSSC 2 at this point?

Until such a device arrives, I think the simplest solution is to use a rotatable mount/stand.

[xtrasmiley]

No, I don’t think an OSSC 2 is in the planning right now…. but it COULD be! 😛

Yeah the rotation of a stand is easiest for sure, but with the FM going out of service life and the OSSC doing pretty much all it can at this point (I know there are some more features marqs is still working like OSD, but still), it might be time to look toward the future?

I mean, my OSSC is not going anywhere, believe me, it’s amazing, but there’s no reason not to look at the next gen of possibilities.

I think a full-on community scaler would/should be an entirely different device; and, unless it could switch off its scaler to run in a line-buffer/lag-free mode and could be built and sold for ~$200 or less, then I don’t think it would be a 100% suitable replacement the OSSC 1.x hardware.

However, if such a scaler were designed to combine the best of what the community has now (OSSC’s line multiplication, RGB/YPbPr inputs, and open-sourced firmware; the RT2X’s/Koryuu’s composite and S-Video inputs; the Framemeister’s digital input and zoom/scaling controls; the UltraHDMI’s framerate conversion and seamless resolution switching) with a few new features (frame transformations like rotation and zoom; multiple scaling methods; switching between or having separate outputs for framebuffer and linebuffer processes; multiple deinterlacing methods; TOSLINK input/output; HDMI input; RGB/YPbPr analogue output; on-screen display), and improve a few things (like the current automatic switching on the OSSC), it could usurp the Framemeister, even at a similar cost.

If you want to make it the be-all/end-all, toss in RF input/decoding (would also be useful as a standalone module), downscaling, design the outputs to be individually configurable (so you can take a 480i/480p/720p game and have it upscaled to 1080p for HDMI and downscaled to 240p/480i for the analogue output), and design the device in a way that would allow us to put it either in an acrylic case for the living room (like the OSSC is now) or in a rack-mountable case.

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.

[BuckoA51]

It was planned for OSSC Pro (there’s even a dedicated button on the remote for it) Of course, not much software development goes on for OSSC Pro right now given there’s only a handful of prototypes in the wild.

[ShootTheCore]

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