Gopher2600 is an Atari 2600 emulator. Although the performance is not as good as some other emulators, it is still suitable for playing games on a reasonably modern computer.

ARM
- improved ARM disassembly, particularly for Thumb-2 instructions
- implementation of FPU and instructions
- registers window in debugger
- COPROC STEP command forward by single ARM instruction
- useful in conjunction with source window, local/globals window and/or registers window
- preparatory work for ARM level quantum control
ELF
- "byte streaming" of ROM data - leading to significant performance improvement
- initialisation sections executed before main() function
Notifications
- notification icon for coprocessor development files
- transparency setting
- fixed conditions under which combinations of notifications are shown
Bug Fixes
- fixed bad image stutter when refresh rate is inconsistent
- crash in timeline window when scrubbing past end of rewind history
- thumbnailing no longer causes the application to hang if the ARM emulation crashes
- FPS measurement was broken if television was being nudged
- "fastload" supercharger ROMs (ie. bin files) would crash debugger
- Known Outstanding Bugs
- rewinding of ELF ROMs when byte streaming is active sometimes produces a skewed image
