I seem to have somehow missed this thread until now. Does anyone have a copy of Nogg's fixed P3?
Regarding Alternate Reality, is the info at http://bringerp.free.fr/RE/Ar/technicalNotes.php5
based on a memory dump, or is it a saved character file format? Have you analyzed the character file format on the ST? (I had a look at a saved Amiga AR character, with a view to supporting this game in my multi-game character editor, and the format seems different.)
