That sounds good, thanks. By the way, I have a Minimig in my parents house (sadly have not used it around two years because of time-problems, but I will change this again soon) and I completely forgot, that the Minimig can be set to Turbo Mode (about 48MHz) in the Minimig-menu. I must try this out, in such of your ported games, that are a bit to slow on Amiga500 machines (like for example "Track & Field"), because I can imagine, that the slowdowns will then be gone, when they run in this Turbo Mode.
And this mode also doesn't mean, that everything runs to fast then (that happens only in a handful of games, mostly vector-based ones), the vast majority of gamesjust hold their normal game-speeds, when the Minimig runs in Turbo Mode, just things like slowdowns in some games (like for example in the Amiga game "R-Type 2", when alot enemies are on the screen at the same time) are completely gone then and such games hold their normal fullspeed to 100% then, in such moments. This thing could especially be very interesting for your ported games, such as Galaga500, Phoenix500, Pooyan etc. I must try this out.
