I just tried it, and I've got:

NeoAntiCrash
Version 1.6

Written by Monolith. Adopted from code written by Neobeo.


Loading NeoAC...
There was a problem loading NeoAC. Make sure the DLL (NeoAC.dll) is in your Jazz2 directory.

Both executable and dll were in jazz2 directory.

Edit: I don't know, maybe I have to edit WINE registry...
