I never played the original Thrust game but enjoyed a remake using svgalib when I first started using Linux. The creator had ported the game to X11 (psuedo color only) but that’s still not usable today. Thrust 30 is a great online recreation but I prefer not to depend on the web site remaining available. The creator also didn’t release the levels as open source.
I grabbed the old version I played and ported it to SDL. I ended up removing all the other graphic modes in order to modify other things. The title screen was replaced because it appears to have been copied from the original game. I took the opportunity to rename the game Inertia Blast. I’ve replaced some of the other graphics with images similar to Thrust 30. Initial Gamerzilla support was also added.
