Need a complete idiots guide to adding programs as emulator that dont work using external app option

Sup dudes!  Been gone for awhile due to Christmas Vacation and then coming down with the worst case of pneumonia I think ive ever had.      Seems everyones dropping like flies up here.   Anyway as the topic says, Im trying to figure this out and I just cant seem to get it.   Ive got a few awesome slot machine collections, IGT Lobstermania and some Hoyle collections and gamex just seems to  hate these titles when I try to launch them as applications from gameex my screen just goes blank for a sec and returns me to gameex.  Ive gotten many other apps to launch using the external application option but not these guys and im dying to add them to my cab.   At first i tried launching them via steam and had problems and then just thought "dangit if im gonna do this im gonna do this right." and decided I did not want to compromise and deal with Steam I want them to launch directly with gamex.  So here I am, pulling my hair out again.   I looked through my older posts on this subject and have been searching the boards and I know you can set them to launch like an emulator and that seems to work for most people but im just too dense to figure it out, and none of the posts dumb it down enough for me to understand.   I mean I know I need to create a blank emulator slot, put all the icons for the apps in a rom folder, point it to that, set the rom filter to *.lnk  (is the astrix supposed to be there?)  and then add [ROMPATH]\[ROMFILE]  in command line (do I type that verbatim or are rompath romfile just placeholders and I need to add the actual path in the spots?  Do I need to do it for each game?)   I donno.   I just really need someone to hold my hand and walk me through this one thing as its driving me nuts.       If I could get my casino games to work id be set.  Any help would be super awesome man.
