Good game and good port! I saw, that you made alot of good ports of Atari-2600 games to the C64 in last months. Very nice!
A 1-to-1 port of the Atari-2600 "Phoenix" game to the C64 would be fantastic. Even when the Atari-2600 port of this game looks and plays quite different to the original Arcade-version of "Phoenix", it doesn't matter much, because the Atari-2600 version of the game has it's own charm and plays really very good. It's my favorite game on the system and not only mine, alot of people like it on this console. Having exactly this game also on the C64 would be superb. Maybe you could think about it?
