I use it and it is awesome and downloading .atr files takes just 5 seconds at most and I have 2 usb joysticks and one lights up. . . . . . .
That's interesting. I just searched it and ended up here: http://www.virtualdub.org/altirra.html to read a little.
I was never into the Atari computers but it looks like this gent put a lot of effort into it from a wave of nostalgia. I might give it a whirl, I absolutely LOVE emulators!
Thanks for the heads up :)
Atariage.com has quit a few emulators you might want to check them out. . . . . . .
Very interesting, goes to look.
cheers
