The new V1.1 adf gives a nice speed-boost on 7MHz Amiga500 machines, when comparing it to the V1.0. Good work jotd666. The fact that the game now skips every second frame (25fps mode) is actually not a real problem in a game like this. It's noticeable, but not a real problem for the player. This skip-every-second-frame mode is roughly equivalent to skipping 5 out of 10 frames in the M.A.M.E. emulator for example. The game still don't run in real fullspeed, when comparing it to, how "Galaga500" runs on an A1200, but it's clearly faster than v1.0 and that's nice.
It would also be interesting to see, how playable the game remains, with an even higher frameskip setting, say, skipping 6 frames out of 10, or 7 frames out of 10 (or, if that's technically not possible, a constant 16,67fps mode, which would be "skip 2 out of 3 frames"). Just to see, how it handles, since that should provide another speed-boost. In scrolling games of course, that sort of thing is disastrous and such games become nearly unplayable, due to severe stuttering. But for a game like "Galaga", it might be worth testing. Worst-case scenario could only be, that the result is, that it’s no longer playable, but perhaps it might still work?
