And btw, Falcon 5.0 is in development :-)
I did spend quite a few afternoons with the Amiga version, https://www.youtube.com/watch?v=Tcry314I7Ro
Unfortunely modern sims require top cards, which spoils the fun.
I love seeing new games for "retro" machines, it's awesome that people keep pouring time and love into them after all these years.
I'm not super familiar with 8-bit Atari machines, and found the designation "classic unmodified 8-bit ATARI XL/XE" a bit imprecise. Tried looking up specs on Wikipedia [1] but was unsure what to settle on. Perhaps the original 1200XL would match? Or the 800XL which seems to improve on the 1200XL even though the naming suggests the opposite ... Or the 65XE, or both then I guess since the latter is compatible with the 800XL, but in an updated case?

Just WOW.
