The sequel one works just fine and I know that it's not that up to date, even though it's 1.0 it doesn't run as fast as I'd like for it to be Basically it runs ~20% slower than on my actual calc(the second one), and the xlib ti-basic gaems with the 2x speed mode run almost as fast as on the calc itself. I'm sure part of it is that the ds isn't that fast really at all. And I was hoping to have a simple way of going at it, but that's the one game that gets stuck on the "set contrast/refresh rate" screen. The second one runs just fine andseemingly at full speed. Both are the axe versions, I'd not dare attempt to run the original basic ones due to how slow oher basic games run.
