Don't you get it? If he gets dosBox AGA working 100% with 20 fps speed on an AGA Amiga 060 (which I find that to be the biggest feat I have seeing on computer world) there will be no need to port Ultima 7 or any of that. All you need is dosBox itself to play Ultima 7 on your Amiga. Since Ultima 7 is really a DOS game.
Actually the reason why Exult was created in the first place is because Ultima 7, even back in the DOS days, was a royal pain to get to work (I know, I bought it when it first came out, since I've always been a huge Ultima fan).
It has a weird custom extended memory manager. This was why Exult was such an awesome project.
While we're on the subjects of ports. One game I would love to see ported to the Amiga would be Phantasie 2. 1 and 3 came out for the Amiga, but it seems the only two platforms that all three were released for was the Atari 8-bit and the Atari ST. And the Atari ST versions are pretty ugly. I almost prefer the mostly non-colored 8bit version. I have no idea how anyone would track down source for it though.
But yes, DOSBoxAgA would/will be awesome. I would still need to get an 060 for my A4000D, which aren't exactly easy to come by without just being able to say "well, I could get that... or I could buy a brand new system and just emulate an 060.... but I really don't like the emulation side of things, which is why I bought an A4000D in the first place..
