SMSPlus

 Currently the best and only Master System out there, SMSPlus delivers 100% speed emulation just as most of XPort's ports do. This is pretty much as nice as any of XPort's emulators and has the same general GUI. Space Harrier runs like a dream and all of the other games that I tested run at full speed with sound.

Features
-Cheat Code searching system
-Zipped file (.zip) support
-PAL and NTSC support

Problems

Final Word
SMS is a fine emulator that gives you exactly what you want, full speed SMS emulation.
