Re: 15 kHz Scart RGB

There were lots of CRT TVs that didn't support RGB through SCART.

Re: BBC Micro

So I've managed to find the bug that stopped Planetoid :D from running, and other 6522 related games like Snapper. The problem is that the SHIFT and CONTROL keys pause the games and Planetoid uses SHIFT. I haven't got a clue what is causing these keys to pause Acornsoft games. Any ideas? Latest vers...

Re: Atari 2600 VCS RGB SCART

I did it myself. :D

Here's the 2600 with RGB 15khz support, supports mist.ini scandoubler_disable. Let me know how it works and then I'll upload it to mist github.

Re: ZX81 and TV RGB output

Could someone with a real ZX81 on the same CRT as the MiST measure the top and bottom of the display (where text is displayed) and compare it with measurements for the MiST? Or a screenshot of the two. A simple basic program: 10 print "HELLO" 20 goto 10 I think there's a VGA timing problem...

Re: ZX81 and TV RGB output

rittwage, does your CRT TV tell you the Hz? Mine doesn't. Is it definitely 60Hz for PAL, 50 for NTSC?

The top of the screen is skewed, that's a flaw in the original ZX81 video output.

Re: New MIST core: PC Engine!

I've fixed the RGB 15khz problem and posted the updated binary below. I've let the original author know so he can add it to his source. There's still a problem with the image too far to the left though, but that also appears on VGA too.

Higgy, I did have a go at applying that 6522 patch but either my code was wrong or the patch made no difference.

Re: BBC Micro

I've fixed the non-appearance of the OSD in RGB 15khz mode. I've also fixed the washed out colours in RGB 15khz mode. Please test and let me know.
Any idea how I get these source code changes uploaded to the MiST github repos? :cheers:

ZX81 and TV RGB output

I've added TV RGB (15khz) output to the Sinclair ZX81 core. core.zip This was a learning exercise for me with FPGAs, verilog and the development/debug environment, as I've never touch FPGAs before but have C/C++ experience. I'd be grateful if some Sinclair/CRT fan could test it to see if it works on...

Great to see so many arcade cores, thanks! This is very exciting work. Is it going to be possible to do 90 degree rotation on these or will I just have to get used to neck ache?

Re: New MIST core: PC Engine!

Yes, same problem here with the sync problem. I don't have a VGA monitor anymore and I prefer to use 15Khz with these retro cores which work great on my Sony TV via SCART. I've had a look into the video timing issues but I can't see the problem.

Re: Updating the core spreadsheet

ZX81 works in PAL & NTSC, no 15khz.
Atari ST 15khz mode doesn't work in "Mono" mode, the default Atari ST mode. Needs switching into "Color" mode using VGA first.
PCEngine screen constantly rolls in 15Khz.
QL works in PAL VGA and has "OSD core swap"

Re: BBC Micro

The popup menu F12 doesn't work on SCART RGB 15khz, works fine on VGA. Where's the best place to log bug reports for this?

To start the beeb.mmb menu you type *MENU at the command prompt.

Re: BBC Micro

OK, so I figured out how to get the "beeb.mmb" to start its menu by typing the following at the prompt:
*DBOOT 0

How do you get the "auto boot" option to work?

Could the information be added to the core's readme.md?
