You will not really be able to achieve "pixel perfect" for many games, but you will still be able to make them all look good regardless of the size mismatch. There are two attributes defining 'screen resolution', there is spatial resolution and temporal resolution, where pixels and aspect ratio is much less of a problem compared to timing and refresh rate. Native resolutions are simply not emulated in MAME, for that you will need to use some other build or some external utilities. MAME is no longer trying to emulate games as close to the original hardware, they are now porting games from "Arcade" to "PC/LCD" hardware platform, and many authentic properties are now being simulated, instead of emulated, and converted to fit inadequate or inferior PC/LCD constraints. Video amps don't effect clarity, they effect saturation.
The thing about a 60hz signal damaging a 31hz monitor is a myth. frequencys effect the ability to get your monitor to sync and nothing more. The only thing that could damage your monitor is if a higher voltage were to go through it. unless you want to see the bios (tip: you don't want to see the bios) letting the bios run at a higer frequency for a few won't hurt your monitor. You don't need 31 khz signals at the bios. it's more complicated but you can generally get some arcade resolutions out of a radeon. The proper signal really needs to come out from the start. Any time you convert one signal to another you get some quality degradation. HW stretch generally makes things "blurry" on some video cards.Īs for the quality, it's probably that down-converter man. Turn that off and turn "switchres" to on and the resolution to either a really low, fixed resolution that works for all of your games or to "auto" and that should help. No, you shouldn't be using hardware stretch at all if you can help it. Resolution0 ideas? I really want to get this to play games at the right resolution, nice and sharp. When I load up Donkey Kong for example, the screen looks like this: Resolution0 am running Windows XP with 640x480 32 bit color desktop using a Radeon 9550XL (not an ArcadeVGA Card) through a VGA-to-CGA Converter Card into my Sanyo 20EZ monitor.
I used the Arcade VGA Res utility to generate individual ini files for every game.įor example, the donkey kong ini file has this information: ini file is default except for these settings I changed: Version 0.142u3 compiled (no nag/hi score) I really need help setting MAME up to run games in their native resolution as pixel perfect as possible to the originals.
