Yes, I imagine Raw Thrills are getting pretty peeved every time one of their recent games gets cracked and made playable. However, Afterburner Climax is nearly 20 years old now (which is kind of mind blowing in itself) and is pretty unlikely to ever see the light of day as a home release again, due to all the licensed jets in it. Fortunately I picked up a copy on PS3 when it was still available for purchase.
I don't think there's any difference in the actual 'elfloader 2' version of the game itself, between it and the OG version that was playable in Teknoparrot, as far as I understand it's just superior emulation of the Linux based hardware with elfloader 2 (the original Elfloader doesn't scale up the HUD properly in-game if you play at higher resolutions).
