HI, I'm joseph from italy. I was searching for an HLSL preset for mame 142u5 like "arcade ideal" for 142u4 by Just Dessert (u4 preset are not compatible with u5). I tried all presets posted in this thread but they are too slow on my core2duo E8400 3.0ghz with Radeon 5850 1gb and not so close to a real arcade monitor like the "arcade ideal" on u4.... I also wrote an italian guide to HLSL activation ( http://www.mameitalia.net/index.php?showtopic=14189 ) and I'd like to add new preset for u5 and later versions of mame as soon as possible. can someone help me? thanks!
