Gopher2600 v0.10.3 is released. Gopher2600 is an emulator for the Atari 2600. Whilst the performance is not as efficient as some other emulators it is none-the-less suitable for playing games, on a reasonably modern computer, at the required 60fps. (The development machine for Gopher2600 has been an i3-3225, dating from around 2012.)

Gopher2600 v0.10.3 changelog:
Moviecart format changed to better support new kernel. This update will cause new files to play correctly.
Old Moviecart files will still play correctly but with wrong colouring in places.
Referring to the Moviecart project itself for clarity: files in the "format1" directory will play correctly while files in "format0" will not.
