Sync pin 20 to 12 switch was my idea, I suggested it to @Frank_fjs for the adapter I asked him to design, just saying...

Thanks!

Do you think it would make sense to design a PCB for the OSSC that routes the HSync/VSync from the OSSC's HD-15 input to Scart input? Soldering two cables is easy enough, but it could be made even easier, faster and tidier.

Edit: ^ The above is in progress

Not sure if this could be changed, but I feel the MWP 606 plastic enclosure that covers the exposed terminals could be slightly improved. I got one with my HAS and it works great (currently installed it on my Egret2 MWP 606). You can't insert a crimped 3.5 connection where the FG (field ground) is since no notch was cut. Anyway to improve this? @RGB

Also is it possible for the HAS to have stereo through the jamma edge of a MV-1F if I toggle the mvs audio switch? Not sure if it is supported via the HAS but Frank_fjs points it out on this thread.

Do you mean that your cover isn't correctly printed? I verified all covers (I had to use an external service, I don't own a 3D printer - yet), there should be a notch for the FG.

The HAS V4 does support stereo through the JAMMA edge - https://homearcadesystem.wordpress.com/instruction-manual/

I can just flip it around but I like having the wires go down instead of up since my Egret 2 PSU adapter wires would need to be torqued a little (they are pretty heavy gauge, not really flexible). I don't really care too much on my Egret2 tbh since I just wrapped the wire around the FG (which removed this annoying noise). Good to hear I can just switch it around when I get another for my other MWP 606 that I use on the HAS. i'll pick up another whenever those 3p/4p adapters/composite s-video adapters get back in stock.

Spoiler

So the MV1F can get stereo as long as I switch that jumper to stereo on the HAS if what @Frank_fjs stated is correct. Just wanted to make sure.

There's no stereo jumper, there's a switch. Please read the instruction manual, just in case.

Hey guys, I finally got a Retrotink RGB2COMP box and it is very sweet! I'm using it for my consoles that have native RGB out to a Sony Wega that has component in, it looks great, but of course, the next idea was to check out the HAS on it!

Most games look fantastic, but a few, such at Truxton (shifted to the left, cutting off the bottom of the screen) and Trio the Punch (cuts off all the info on the bottom) cut off portions of the screen that have useable info. These are the only games I played tonight, but it's not a huge deal, just wondering if there is a way to adjust screen position with the HAS or resolution being fed into a TV via RGB (SCART cable) into an RGT to component box.

Thanks again to @RGB for such a wonderful SuperGun!

I use this device from Aliexpress to position games on my CRT that are shifted when using the HAS:

I've had it for awhile now and it works great. I have an older PVM which you need to adjust pots on the inside of the case instead of a OSD. This is plug and play and I can now played Volfied perfectly centered which displays seriously downshifted with my HAS. Plus it helps with little tweaks here and there depending on the game. Hope this helps!

 

[Frank_fjs]

I use the same device, it's brilliant.

There is anything to rotate the screen image without rotating the display? It would be extremely useful for those shmups that want a “portrait” display.

It's been discussed, the problem is we would need to mat the image to then re crop it to proper ratio tated ratio.
This could be accomplished with a frame buffer, but that would add significant 16~32ms (about 12~24 frames) lag (the games would be unplayable afterwards).

A real time transform without a buffer far as I'm aware isn't possible.

Actually, I think it could be down to only 1-2 frames of lag with certain current equipment. That being too much is up to the player. I'm hoping the next gen of OSSC or whatever might have this feature.

Thank you, perfect!

Hmm, now, could this feature get built into the next version(s) of the HAS.... ?

No brother . will not be part of the next HAS , but Mike will release something about . Cheers

Not possible, it takes 1~2 frames just to fill the buffer.
Then you have to process and output said buffer.

You might be able to get it down to about xRGB mini levels of lag, but that's 16ms (aka not good).

How could it ever take more than one frame to fill the framebuffer? The framebuffer is filled every frame. It is right there in the name: framebuffer.

And you can ignore the time spent outputting the processed frame. Again each frame will take one frame to output. But there is no lag added with the output.

 

[jassin000]

"A frame buffer may be designed with enough memory to store two frames worth of video data. In a technique known generally as double buffering or more specifically as page flipping, the framebuffer uses half of its memory to display the current frame. While that memory is being displayed, the other half of memory is filled with data for the next frame."

You need to be able to page flip out the frame to the processor, so you need the double (aka it takes 2 frames before the process/output is even taken into consideration).

You are radically misunderstanding how double buffering works. The whole point of double buffering is that you can process the first frame while the second frame is filling it's own independent buffer.

This is my understanding of how the technique can be used for matting/re-cropping, it maybe (and is likely) flawed but unless you (or someone else) can explain it better I'm going to accept/keep on using this interpretation.

@Frank_fjs and @ChopstickSamurai - this device looks amazing! in my cabinet where i swap boards out I always have to monkey with the position, generally using the pots on the monitor... this devices looks awesome! Its as easy as it looks?

[Frank_fjs]

It's very easy. Two pots, turn one to shift the screen up/down and the other to shift left/right. There's also a switch if you want to enable or disable the device.
