Working on a Linux Arcade Distribution for Cabs

Thank you for this good note. This is a problem, which a lot of people will have. So I created this afternoon a screencast how to do this. A written tutorial will follow asap.
--- Quote ---Again forgive my ignorance but when you say "You will get the linux console screen at 15Khz" what are you meaning exactly? Is that the refresh rate you are talking about? That is what arcade monitors normally run at correct? Will this even work on a PC monitor? Sorry if the answer is obvious.

Yes with 15Khz I mean the resfresh rate which is needed when you want to operate a system on an arcade cab screen. A PC monitor is not able to deal with such a low feresh rate. Thats the reason why you can choose after power on of the PC, where it is connected. By default it assumes, that the system is inside a CAB and chooses the correspondig mode automatitcally, but you can choose manually the PC-Mode to get refresh rates for a PC monitor. Important for testing or putting ROMs on it.
--- Quote ---Another thing I was thinking about. You said that this should run on slower systems (slower than 800mhz) if the games weren't too complex. I wonder how low you can go for say the "classics" ie: pac, frogger, donkey kong, asteroids ect. ect.

Indeed this would be interesting to know but is beyound my experiences/testing. In other words, try it by yourself. A guess is that Pentium II/266 would be fast enough for this.
--- Quote ---Oh ya, aren't those Matrox cards AGP types? (if I remember right) Did they make G200 & 400 that were PCI or ISA?
--- End quote ---
I am not sure, but I think you are right. There are also some G100/G200 PCI Version available. With a G100 you can expect the same results on a slow system like with a G200 or G400. But if the system is fast, I recommend using a G200/G400 to avoid that the graphics card becomes the bottleneck of the system.

Interesting. Im using gentoo at the moment but I may give this a go. Will it work with this? http://www.nexusuk.org/projects/vga2scart/ I haven't made one yet but I plan to.
Keep up the good work

Haven't been on the boards a lot over the last year and just found this thread.
Wow! I'm gonna give this a whirl when I set up my other cocktail cab. I made the transition to Ubuntu Linux about 3 months ago and am loving it.
Haven't tried it yet, but a big hefty nice job!

The "KHz" rating of a monitor refers to the horizontal scan rate that the electron beam travels at as it draws pictures to a screen.
15KHz refers to "CGA" resolutions - the resolutions used by older genuine arcade hardware, and standard definition TV. These sit somewhere around the 240 lines ("320x240 resolution" - remembering CRTs don't understand resolutions per se, but just lines drawn across the screen) at roughly 60 frames per second drawn progressively, or more recently around the 640x480 resolution at roughly 30 frames per second drawn interlaced (ie: half a frame in one pass, and the other half in the second pass).
31KHz are VGA resolutions, or around 480 lines ("640x480 pixels") drawn at 60 frames per second (or in TV land, "480p").
For a far better explanation of all of this, and the intricacies of monitors and scanlines, check out this excellent guide:

Definitely watching this with interest. Great concept!
