Quote from the author of Chimera remake, Tezz, on AtariAge forum: "This is my new remake of Shahid Ahmad's classic game Chimera for the Atari XL XE. Chimera+ is a complete rewrite of the game from the ground up to create an enhanced version with the goal of optimising performance for faster gameplay, changing the controls and, adding the features missing in the original Atari release. The new version works on both PAL and NTSC machines with a minimum of 48k."
