Gopher2600 v0.30.1 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 v0.30.1 changelog:
Improvements / Fixes
ROM selection window could stall the GUI if there were a large number of files in the directory. Directory reading is now asynchronous and solves the problem
Rewinding could cause the TV screen to resize with some ROMs. The size would always settle correctly but the one or two frames of incorrect size was visually jarring and unnecessary. Fixed
