This was probably my favorite game on the Amiga. If I remember correctly when I went from my A1000 to an A2000 with A2620 card, other than playing smoother the pilots helmet would flash/blink which I assumed was from the 68020 vs. the 68000. Though that could have been playing it on my A4000 68040....it's been a while
This is the only game I've purchased since getting back in to Amiga, code wheel and all. Here's a video of it running in demo mode on my Amithlon system in E-UAE (so an Amiga emulator running in an Amiga emulator).
