Note that although Total_Noob announced that his Hen will not have ISO support, several teams are already actively working on game Loaders (such as Open Idea Iso Loader by dridri, which supposedly loads ISO/CSO and PSX games). Such loaders will probably be made compatible with firmwares 6.xx with little effort, and I am more and more confident that it will be a matter of days after the release of the Hen before things such as iso loading or plugin support are made available.
