hmmmm...that look like the asr.dat file I got for Winkawaks1.46... with loader.... not sure if anyone has talk about or used this before... it did not work though I only renamed some roms did not try any thing else... kof2003kawaks.zip if your haveing trouble...with performance in mame.. try changing the resulotion....can't see why it would be choopy... neorage games need a minimum res of 320x240....and set cleanstretch to none....this way it displays at it's native resulotion.... no extra work for you video card..
