Recently I've started rebuilind my arcade PC with mame 163. I was curious how version 163 works with certain games but I ended testing most of sets in game (excluding mahjongs, not working (with few exceptions), fruit, mechanical etc.) All tests was done with G3258 overclocked to 4,2 GHz, Asus H81M-E, Kingston 2Gb value and Win 7x64. Test was done using command mame64.exe - bench 299. Maybe it will usefull for people planning upgrading/buying hardware for mame.
EDIT. Added tests for mame 205.
