Maybe the issue is driver dependant:
I've made a test on 2 computers:
on the first one (Win 7 x32) with an integrated intel video card, it runs fine on 32b
in 16b here is the crash i get:
Application : EmuHawk.exe
Version du Framework : v4.0.30319
Description : le processus a été arrêté en raison d'une exception non gérée.
Informations sur l'exception : System.AccessViolationException

On the 2nd one (Win 7 x64) with a GeForce card, it runs fine on 32b depth, when switching to 16b i got no crash but the Bizhawk windows never shows, but the exe is visible on the task manager
