SMS Plus

SMS+/MacOS is a Sega Master System and Sega Game Gear emulator for the Macintosh. The hardware for the Sega Master System and Game Gear consoles is almost identical from a technical standpoint, which means that when you emulate one, it is trivial to emulate the other. SMS Plus features accurate emulation of both systems, with full sound support. It can even use GZ compressed ROMs transparently.

What is new in this release:

• Audio recording no longer stops when emulator is switched to background, provided that the option to keep emulating in background is on. Recording will still stop if the emulator does.
• Brushed metal mode is now off by default on new installs, as well as existing installs where users press the Default button.
• Fixed an obscure endian bug that resulted in odd window sizes when an emulator preferences file was moved between PowerPC and Intel.
• Fixed several minor visual glitches in the Preferences dialog box.
• Modified the behaviour of the Quick Freeze function, so that the last ten quick freezes for each game are kept in ~/Library/Application Support/Bannister/(emulator name)/Saved States. You can restore these at any time using the Defrost menu command. Added code to stop the quick freeze and quick defrost keys from being repeated. Thanks to David McCabe for the suggestion.
• Replaced custom about box with standard HIAboutBox. Removed option to pause execution when about box is open.
