avih, thanks for compile and checking it out, if you hapens to have Haunting Ground, try it, there's quite a difference.
and more info about this patch i forgot :
additional "hack" function added, such as toggling textute cache on the fly (this i only direct translate), skip layer, skip bad processing and etc..
gotta compile it and playing around with it
and a built in different color engine base on this website, an internal filter(direct translate) which say can display sharper image which i don't really see any difference
http://gens32.emubase.de/ (seems down atm)
some different color enhance profile preset, i don't really care about the color but maybe others will find it useful?
maybe there's more though, but it's time to let the Dev figure out then^^
it's abit hard for me to write in english though, better keep this short
