I don't use a folder called "artworkgameex'", I've neved had. The path is correct "L:\Emulation\Systems\MAME\artwork". I've made a "find in file"-search for "artworkgameex" to see if it existed in a configuration file somewhere, in the MAME folder and the GameEx folder. I did find this line in a file called runitgame.bat: mamepgui.exe 1942 -rompath L:\Emulation\Systems\MAME\Games -triplebuffer -hwstretch -nowindow -joy -noswitchres -artwork -artwork_directory artworkgameex and I found a folder called "artworkgameex'" in the MAME folder, which I never had seen before. I deleted both the file and the folder and tried to run a game from GameEx again, it didn't work. But now I noticed that GameEx had created both the runitgame.bat-file and the folder. GameEx seems to be making that folder name up from nowhere. I'v e tried deleting the artwork path entierly in GameEx.ini, disable/enable artwork in MAME. Nothing helps. Btw, when starting games from the MAME UI, every game works, with or without artwork. It has to be some kind of strange bug. The GameEx version is 9.42. /Niclas
