@RetroFreak89 I know this is a little late to the party - but there is a program called Exult, which is a recreation of the game engine that Ultima VII used - and there's a linux version of the source.
I haven't personally tried to build this on a Pi, but....
In theory, it could be done, and you could have a more 'native' running version.
I used Exult's windows builds many moons ago, and they were pretty stellar for usability and such. Many bugs were fixed, more modern systems are obviously supported, etc.
If all you want to do is play the game - this is a good way to go.
If you absolutely must have the original exe - then dosbox is likely the best way to go - maybe specfiically "dosbox pure".
Either way, google will get you to Exult or DosBox Pure..
Good luck, avatar!
