Yeah this is exciting news. I have given it a go and it is really fast and smooth, boots up very quickly from cold too.
So are you thinking about doing a native port of Archimedes Elite to Risc OS or getting it running via an emulator?
I've also been playing around with riscos on the pi and agree that it is fantastic! It's been years since my trusty old acorn electron and a (borrowed) arc 440 and the BASIC programming is still in a dusty corner of my brain waiting to be poked with a stick
I completed the gertboard last weekend so it's on to risc-ing with it in the next few days... exciting.
With regards to a pi port - i really think it would be great to get oolite running on the raspbian distro rather than fire up the old arc elite. Mainly as I imagine that it would be a bit easier being based upon an existing linux distro but also because (and no disrespect to my acorn brothers & sisters here
) I just think that oolite is better than the origonal elite, arc version or not.
The other great reason for getting it going on a pi would be to create a case shaped like a cobra mk3 to put the pi in to - thereby creating a model of a ship that plays the game.
