Is it just .DGE files you need help with.. Or others as well ?
For in-built Emulators you may already know..
Each game rom need to be in their appropriate folder (ie) Neo-Geo files put inside Neo-Geo folder and just click.. the rom to start game.
For .DGE Roms..
you must put in the root folder.. in there own named folder..
(
DO NOT CHANGE THE FOLDERS NAME FROM DOWNLOAD) .. also do Not rename the (
whatevername.dge) file also..or they will not work.
open the unchanged name folder from root and find the DGE execute file in the folder and click on it..
I hope that helps.
