I haven't been able to play World of Xeen (i.e. MM4 and MM5 on the same drive) for years, because the DOS shell on my old (and now defunct) computer didn't have enough low memory to cope. However, I installed Dosbox, and I've just completed Clouds of Xeen. The only flaw in the game was that the Thieves throne in the northern sphinx refused to confer the "Prince of Thieves" title on my dwarf ninja
I'm having to take a break for work just now, but I've started on the Darkside, and Castleview has been cleared. To be continued . . .
