Sadly with SVGA output, will be not possible to test, because VGA cards over SVIDEO only output  full NTSC or PAL interlaced signal,  720x480 or 768x576

Is not possible to output real 240p progressive signal

But if you want, i can help you to test all you need, at least, i can do something, not just came here to ask...
What kind of cable do I need? VGA to SCART? Is there one that I can buy or must I make it?

Your help will be appreciated. I need to do a bit more work on it then I will ask for your help.

Hi!!

For output 15kjhz 240p, on a normal PC, you need this





1 - A VGA to Scart RGB cable + molex or usb

You can make one or buy one already made.  Must be a arcadevga cable, not a regular VGA>RGB cable without molex or USB

Something like this, the best

Cable VGA RGB ARCADEVGA A SCART CON JACK SONIDO ( EUROCONECTOR ) JAMMA ARCADE |


or this

VGA RGB ARCADEVGA TO SCART CABLE ADAPTER ( EUROCONECTOR ) for JAMMA system |



The best website for this cables i know is this, is from spain, maybe they send to UK


http://retrocables.es/tienda/index.php



Is cheap, and they have USB cables, then you dont need a molex


I preffer molex cable, because molex give 12 and 5v,  USB just 5v.   With 5v the cable change to RGB mode, but not AV mode, then you need to change manually your TV to AV


If this is not a problem, USB is much simple



2 - A compatible graphic card with soft15khz or emudriver (ati)... (or buy a arcadevga.. expensive)



Soft-15khz - BYOAC Wiki


CRT_EmuDriver - Windows ATI Driver for GroovyMAME




In nvidia, nothing less  geforce 2, and no more than 7300.  8xxx and Up need a Dongle

In ATI,  nothing less a Radeon, and no more 4xxx series, more need dongle

Matrox, sis, 3dfx... unknown for me, i did not test


Integrated intel, dont work, in this case, you need DTD, puff.. difficult







3 - Winmodelines to make/ajust the modelines you need


WinModelines | Retrovicio



4 -  I totally recommend  quickres1 for change resolution

files.arianchen.de - /soft15khz




5 - Important...  normally everyone works in XP


Really, I dont know anyone using 15khz in Windows 7 or 8... Maybe works...dont know




One you have everything installed, is just plain easy, nothing special

Just install emucrt drivers if you have a compatible ATI, or soft15khz if is a nvidia, matrox, etc or ATI, and you dont wanna change your current driver

Next reboot, you are in the 15khz world


emucrt is just a hacked ati driver, with some good modelines and addons

soft15khz, make your current driver compatible with  15khz



I think the best for you, just for test,  is use a old computer, like P3 or P4, with a compatible graphic card ... for sure you have one in some corner... :)

Hi!!

Any new news about original resolution?

Greetings
My plan was to connect an old tv to an old pc.

my pc has vga, dvi and s-video.
my tv has composite and scart. no s-video :(

Also I don't have a conversion cable :(

So my plan didn't work.

Now I will change the code, can you test it when I have done that?

Oddly enough, I saw a VGA to Composite Lead yesterday, though I have no means of obtaining it  :(  Though I presume that's the sort of thing you would need?

VGA to Composite? I assume it's more than a lead then, ie: it has electronics and needs a power supply too. Or do you mean VGA to Component?

Sorry, yes it would be VGA to Component, I'm always getting those mixed up.  :(


Guess it would just be easier to get SCART to VGA adaptor?

It would have to be a low frequency VGA (15khz) , a CPC monitor couldn't handle 31khz.

Hi!!

For 240p output,   VGA to RGB SCART + soft15khz or modded drivers is a must, is not possible, at least i know,  to output 240p from svideo connectors on videocards


About a CPC monitor,  if you have a CTM640 or 644, is just a regular 15khz screen with a  standar 6 pin connector. The only problem must be that CPC monitor expect CSYNC in pin 5, and VGA output Hsync and Vsync

But, ATI card can do composite sync from driver, you can control this on catalyst panel


If you output 15khz from your PC, no probem




About emulator, of course i will test, and will help in all i can, thanks a lot  (Until october 10, I will be traveling because work, but after october 10, i can do any test)

Hello, I'm going to recover this post. Is there any available emulator in native resolution? I've tried MESS but it's forced to 800x600, it seems it doesn't support correctly 720x288.


Thanks.

With PC-CPC you can set the resolution of the emulator by choosing :- Video/Configuration- And checking the box "FenĂȘtre sans bordure", then set "Resolution X" and "Resolution Y" , finally click "Valider"
