There's a programme that comes with WRPtool (island editing programme), called ODOL Explorer or something. Aparantly you can save the BIS MLOD format to an OLOD format or something so you can edit it with 02 (addon making programme).
But what magneto is probably talking about it de-pbo it and changing stuff in the config (like different weapons - m2a2 fires LGB's for example).
I know this crap cause I can make islands, addons and missions.
