They will work if they are correctly converted - see that FF3 wad, good work.
Basicly if the wad needs hacking to work on the PC it won't work on the GP32 without some extra PC based alterations.
I *think* dehacked alters the doom EXE on the PC so it obviously won't work on the GP32 as the exes are diffrent, however in most cases the wad can be hacked into a stand alone wad and be made to work (ie FF3)
If you have not tried the FF3 wad you should - it shows just what coolness you can do with the doom engine, i thought the double forest effect on level 2 was really good, the cartoon look works so well with the doom 2d sprites, also the water creatures (lock ness monsters?) were a clever trick too.
Hopfully we will see a whole lot of these total conversions being made to work on the GP32 and maybe some GP32 new ones?
