Soft-15KHz - slim new tool for 15KHz on normal vga cards
isucamper:
This may have been addressed somewhere but I couldn't find it.
Is there a modeline I can use with an NES emulator to get the native resolution (256x240) and native refresh rate (60.098hz) of the original system?
My issue: I want to be able to run NES games without screen tearing and without enabling V-Sync. Enabling V-Sync induces lag in the emulators I've tried. On Nestopia, the lag is very obvious. On VirtuaNes, the lag is almost imperceptable but I know it's there because I can't beat Mike Tyson's Punchout when it is enabled. In fact, the only time I can beat Punchout is when I use Nestopia and disable v-sync. VirtuaNes still seems a little slow when V-sync is disabled.
So, my theory is that if I run the emulator at its native resolution and refresh rate, and play it on a TV, then there should be no screen tearing since its behaving like the original hardware and should match up properly with the strobing of the television.

Can you add an option to exclude some of the "standard" resolutions?
(or allow me to edit the entries before sending them to the registry)
I use the following setup:
- My monitor is configured to display ~288/576 lines which means that 240/480 line modes will not fill the entire height. In mame I fill the borders on left/right with artwork so therefore I want the 240 modes to be "letterboxed" (e.g. 288x240 instead of 240x240) and also tweak the start slightly so they are centered on the monitor.
- I prefer double-sized interlace resolutions since I don't like visible scanlines (specially not in the artwork).
This means that I don't want to use many of the "standard" resolutions but still want to use your excellent tool.
Also, how can you do 800x600x50Hz in 15KHz? On my Hantarex POLO I have not been able to go higher than 47Hz.

My Polo doesn't like 800x600 either, and it doesn't handle interlacing at 640x480. Looks like crap. the WG in the machine right next to it has good interlaced resolutions, but diagonal faint red lines that I cant seem to adjust away.

Thanks to everyone for posting informative information on this thread. OK, I have couple of quick questions:
1- Initially I made a custom built PC runing Windows XP with the following specs:
AMD FX, Asus AMD HD 5450, etc. The video card would simply could not accept 15Khz, and I ended up returning the parts and decided to use my old DELL 2400 desktop with the following specs:
Pentium4 2.4Ghz CPU
2GB DDR RAM
nVidia GeForce 6200 PCI (PNY brand)
Commodore 1084S-D1 RGB monitor (USA NTSC) - connected to the VGA connection of the card above
A custom built VGA to RGB cable (I have tested this and it displays my NEOGEO emulator games perfectly)
LCD connected to DVI connector, running extended desktop and using this as for selecting games and then launching them to the main 1084S-D1 monitor
.
2- Is the above a powerful enough system for running MAMEUI, Neo Geo, Sega, Amiga, Nintendo and other emulators? This is NOT for an arcade cabinet, simply for my desktop gaming sessions

hi, can anyone tell me if there is a soft-15khz equivalent for ubuntu. i know there is the groovyarcade live cd but i believe this does not support amiga or dosbox emulation which is what i'd like to use. thanks
