Sentinel Supergun - Prototype

Just going over the output options as this thread is long and I've forgotten, this will have composite output along with what else?

For most people I am guessing this needs an OSSC to upscale to a monitor? Any other options for output to a modern monitor at playable resolutions?
 
RGBS via Sega Mega Drive 2 scart cable by default.

Optional composite and s-video output via a separate add-on hat.

If needed I can do a VGA hat for the OSSC which will accept TTL sync. It will still be composite sync which I understand that the OSSC supports over VGA.
 
I've been using one of these to output to a modern monitor. It's cheap and works great.

Is there such things such as composite to DVI/VGA/HDMI converters that work well?

I was hoping there would be a way to do this without the additional hardware of the OSSC or whatnot. My goal is not to buy an OSSC or some extra hardware for every separate setup I would use.

How is that device? Does it introduce lag?

Just curious but can an upscaler and HDMI output be built in to the super gun?
 
It probably can since the OSSC is by its name, open source. It would make the supergun significantly more expensive and most people who play retro consoles or Supergun setups etc on a modern TV already have an OSSC or similar...

You don't need a different one for every setup, but you do need an OSSC plus a video processor in the case of boards/consoles with weird sync rates because the OSSC is very picky.

This is why you end up with setups like jassin if you want the best output on a modern display....
 
I know it would add cost, If I run a tourney with two SFX boards I would need an extra scaler for example or unplug and pull out my OSSC from the TV every time I needed it.

For the simplest of integration, what are the estimated costs that it would add?

Could refresh me on Jassin's setup?
 
The simplest integration to me would be to make the supergun PCB have holes that line up with the standoffs of the OSSC. You could just install an extra set of standoffs, have the OSSC stacked on top and run a short MD2 cable for video/audio.
I assume you could also probably tap +5V from the supergun PSU to power the OSSC.

This would also help keep the OSSC from tipping upwards caused by the SCART cable.

Just my 2c :)
 
Beyond my skills to incorporate digital video output. It would require a lot of components and therefore a much larger PCB.

Forgot to mention, can also use a HD Retrovision cable to output component. Some modern displays accept component.
 
Another option which isn't costly:

New Arrival CGA TO HDMI converter RGBS / CGA / EGA to HDMI converting Board PCB for HD LCD monitor arcade game cabinet machine

Not tried one personally but have heard good things about them.

The supergun has header breakouts for RGBS so it would be simple to connect to the encoder.
 
The price of this and the one you posted before are basically the same so would come down to the choice of which one is better.

My aim is to get something that can scale at no lag like OSSC but not at a $300+ price tag.

It's too bad though that digital output is not a simple thing to add at a reasonable price point. Would literally make this more of an awesome supergun than it already is :) Actually I wouldn't care if it was priced accordingly, just not more than OSSC plus supergun separately. One can dream.
 
Those scart to HDMI boxes are pretty bad, you'll have all sorts of nastiness that comes from it processing 240p as 480i.

If you don't want to spend the money for an OSSC, then a cheaper but still good option is the RetroTINK 2X with HD Retrovision cables. Alternatively you might be able to find an old XRG2+ for a good price.
 
I'm happy with the one I have. No lag that I can notice, which isn't surprising as it's a simple conversion. Crisp image and compatible with every combination of game / monitor I've thrown at it. No fuss, no settings to mess with, just simple and effective. Crisp image, just no scanlines. Not as good as an OSSC but much better in terms of price to performance ratio.

Yep I didn't think they would be acceptable.

@MRTCPS2 suggested the Retrotink 2X as well. Can just use S-Video I dont think there would be any difference in using the HD Retrovision cables as opposed to regular S-Video ones?

Depends on the quality of your svideo cable and how it's generated.
