Re: IOBoard VGA to 15khz PAL CRT via RGB Scart

The Commodore 1081s are cheap on ebay (at least here in europe) and they have the advantage, that they come with a composite and a RGB mode, they even have a green switch, which is nice.

Re: IOBoard VGA to 15khz PAL CRT via RGB Scart

If you want a 100% working solution for the picture size and position on MiSTer, go for an old CRT RGB Monitor. These monitors always had controls to stretch, squash and move the picture horizontally and vertically, because the different computers of that time all produced a different sized and posi...

Re: Tip for anybody having low lag syncing problems on the LCD TV

Many thanks for the explanation, I think now I got it, didn't thought about the difference between display refresh rate and input refresh rate. What I still not get is, why vsync_adjust=2 works, while vsync_adjust=1 fails. As far as I understand the difference between both modes is, that vsync_adjus...

Re: Tip for anybody having low lag syncing problems on the LCD TV

I see, that's what I originally thought, but then I tried vsync=2 on 1280x720 and it worked and I thought I got things wrong and vsync=1 is expected to stutter. Do you know if it is common amongst LCD TVs to sync in other resolutions they don't sync in the original resolution? I didn't knew LCD pane...

Re: Tip for anybody having low lag syncing problems on the LCD TV

I already tried this, the result is, that my TV is constantly loosing sync. Especially in the minimig core with its ever changing resolution, the screen stays black for several seconds some times. With 1280x720 everything works fine. I guess it's because I use a TV instead of a monitor, these device...

Tip for anybody having low lag syncing problems on the LCD TV

I use my MiSTer on a Samsung Full HD LCD TV via HDMI. Vsync_adjust=1 works fine in all 60 Hz cores and scrolling is butter smooth with low lag, but on all cores where I use 50Hz PAL (e.g. Amiga, C64) it doesn't sync, so I had either use vsync_adjust=2 which results in stuttering in fast scrolling ga...

Re: Vectrex core

You are right, at least Armor Attack is in fact not in the correct AR, I compared the image on my screen to the video and as you say, the picture is distorted.

Re: Vectrex core

Although I cannot by inspection tell the exact aspect ratio, the core clearly outputs a picture where width > height (try e.g. Armor Attack), If one sets the aspect ratio to 16:9 in the core menu, the width of the picture increases correspondingly. If it matters, I am using HDMI output. I have seen...

Re: Vectrex core

Thanks for a great core of a quite unique machine. There seem to be two choices of aspect ratio in the core, 4:3 and 16:9, but not the original ( 5:8 ?). Is there a reason for this? Would it be difficult to implement? 5:8 is the screen size, not the aspect ratio :wink: Wiki says the Vectrex screen ...

Re: Work on the Minimig core?

AFAIK it's needed because the chipram access is slower than the real AGA chipset would do it. Turbo just turning on cache for chipram access. I'm still not an Amiga expert, but the SDRAM controller can access 64 bit chipram data at a 7 MHz rate (32 bit/14 MHz). Anyone knows the real AGA's numbers? ...

Re: Work on the Minimig core?

This option should be always on for aga games. It should be disabled only for ecs games. This is what I know, because aga machines have 32 bit access to chipram, ecs machines have 16 bit access instead. Excuse me if I wrong. Didn't knew this, I always have turned it off, because the page of the cor...
