Mediocre game, tho the animations of the big lizard (called a "pesky dragon" in docs) are soooooo adorable. Dragon can leap over pits, eat people, chews before swallowing, and keels over on its side when you kill it with your rocket afterburners.
Stellar Shuttle reveals Failed Collision Detect = an embarrassing bug in emulator Atari800MacX starting over nine years ago in v3.3 and enduring to this day in v4.6 the highest. v3.2 and earlier play right.
Emulator bug let's you fly through and shoot at without hitting asteroids. You can even fly through the ground without crashing. Stellar Shuttle is the ONLY one game I've confirmed fails but this bug is spectacular. My guess is it involves a mixed bag Display List and artifacting. The ground is drawn using artifacting (screenshot here was captured without artifacts, whatever) and Atari800MacX v3.3 version history declares a change in handling artifacting.
