i was under the impression that the Gens Emulator would work fine using Wine, and I have had it function once before (although im not sure how i got it to work)... it loads up fine but when i go to load a ROM it just closes... this is a fresh FC3 installation and ive set everything up the same... what could i be doing wrong? 
Stop drinking and you won't have this problem 
A couple of things:
1) Gens probably has a log file. Check the log file for any output.
2) I've been out of the emulator world for a while, but if I remember correctly, there are numerous emulators for linux. Why not just run one of those?
hiwhy use wine
just try it on a phisical machine
