Changes

GroovyMAME (or GroovyUME) is a fork of MAME/UME made primarily to support arcade CRT monitors for AMD cards. It also includes input lag reductions that can be taken advantage of on CRTs or LCDs. However, now that modern MAME versions support variable refresh rate monitors and the "-lowlatency" flag, there is less of a need for GrooveMAME or for other lag-reducing builds such as Shmupmame.
