Newbie TV walkthrough, please!
adder:
hi rcadegaming, thought i would post here to ask u something;
i was previously satisfied with running all mame games in 640x480 interlace, but tonight i have been experimenting with the good old real low res modes with my crt tv. i have been messing around with several programs, namely soft15khz, winmodelines, powerstrip, and crt_emudriver (oh and quickres :)
the early experiments went well, and i got quite a few of the pre-defined resolutions to work (which were added to my windows xp setup by installing crt_emudriver), however there are also quite a lot which dont work on my tv
i remember you saying you have spent a lot of time setting up modelines to work on a standard tv. so my question: would you be willing to share your modelines which you created to work on a tv? if so, please simply post them here, or pm me. cheers!
note: absolutely no problem at all if you dont want to share them, i figured there was no harm in asking!
rCadeGaming:
I might get some time to play with my setup around the new year. What resolutions do you need help with in particular?
rCadeGaming:
Have you read this whole thread? Please make sure to first, as you'll find some tips about tweaking in Powerstrip, what you should be looking for, and things like running a game centered in a slightly larger resolution and adjusting the black border into the overscan.

ok i will read through the thread again, i think my problem is not really understanding how a modeline works and how it is put together, and also why a regular crt tv accepts certain modelines and cant cope with others (ie. i dont know what the correct ranges are for a crt tv)
i have been reading around slowly though. i still feel i am a long way off understanding it all though (hence me trying to take a shortcut and nabbing your ready made modelines instead :lol)
currently im trying to figure out a good way to display a game like 'Image Fight' (a vertical game, 256x384) on a tv mounted horizontally in the cab. so i need a modeline which has about 390 lines on the vertical. im happy to use interlace mode, but i cant figure out if its even possible to make an interlace modeline with around 390 vertical lines? in fact the closet working interlace modeline i can get is 640x480 which isnt even close :dunno

Some of the presets installed with Soft15kHz happen to work with TV's, and some others need to be tweaked to get working. It's in there.

The modelines I make are tweaked to my exact TV and transcoder. What works best with your setup may be different. If you'd like some of mine as a starting point, let me know which you're having trouble with.

Well 390 lines isn't possible in progessive 15kHz, it's too many. Sounds like you read that section if you're suggesting interlaced. 390 is a lot lower than the standard 480i, but MAYBE it's possible. You might be able to get close and work with geometry from there. I'll look into this.
