I'm upset that arcades are disappearing and I'm mad that companies have stopped making CRT arcade monitors. I sense you've got some sort of "you damn kids, get off my lawn" thing going on with the new versions of MAME. GroovyMAME also incorporates options borrowed from other custom builds like "soundsync" that adjusts the playback rate of the sound buffer based on emulation speed to eliminate skipping and other sound hiccups. GroovyMAME does all that work for you on the fly. You can still get the same results for the most part with one of the official MAME builds, but you have to create a lot of custom INI files for each game. Calamity has custom ATI drivers for use with GroovyMAME that have been modified to have 120-160 custom resolutions and the results are pretty amazing. GroovyMAME does the automatic resolution selection on the fly so no custom per-game ini files are needed. GroovyMAME is a custom MAME build along the lines of AdvanceMAME that is designed to match the emulated resolutions and refresh rates to the available refresh rates of your video card. The recent changes to MAME that you are talking about (HLSL shader effects) are just optional eye-candy on top of the normal emulation to simulate the look of arcade monitors for people with LCD monitors. Yes, arcade monitors are second-class citizens in the MAME framework, but in order to have accurate emulation, they still need to emulate the exact refresh rates, resolutions, and timings as the arcade machines, even if the final display target is a PC LCD. You have no idea what you're talking about. XXX-in-1 bootlegs run AdvanceMAME via regular video card, so you can take that as reference. There is software that makes regular video cards do everything better. I am not sure if ArcadeVGA supports variable refresh rates, but you do not need it in any case. Worse part of the problem becomes more obvious once you start to really play those games, particularly scrolling ones, like Scramble or Moon Patrol, and especially if their refresh rate mismatches 60fps, as they often do. 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.
