No. My Amiga knowledge is very low. And as I see there is much more Amiga game adapted for hard disk run than Atari one.
And as said in other thread, gamex is not for speeding up games. If machine is set on max speed (what HW allows), and if then game still has bad framerate it means usually: forget it and try some better game
Not that it is impossible entirely, but not worth of time and effort. After all, all this is retro.
