Brunni has updated his MMSPlus Sega Master System and Game Gear Emulator for the PSP today to version 1.1. This emulator is undoubtedly one of the best SMS emulators around, with no shortage of updates to add new features and bug fixes so that you can play al of your roms on your PSP at full speed. MMSPlus has been coded in C and was based off the original source of SMSPlus, a PC SMS emulator by Charles Macdonald. You'll also be pleased to know that most SMS games run perfectly at 166 MHz and Game Gear at 133 MHz. Here's whats been added since the last release:

* Added VGM support for the menu (VGMs are SMS music files)
* Added VGM GD3 tag support
* Added Screenshot option. Screenshots will be saved as png to a MMSPlus folder in Photo.
* Major GUI update
* Disabled returning to game after choosing exit from the menu. Previously after choosing exit from the menu it would show the last game loaded briefly before returning to the xmb.
* A number of minor bug fixes

Thanks for the tip Mister Cheif!
