Zega Alpha (dawniej vbsms+ czyli vbsms Johna "brom" Caseya z dodatkamia autora) jest emulatorem konsol Sega Mark III, Master System i Game Gear autorstwa Kevina "olaf" Millera, napisanym w Visual Basicu. Wśród typowych narzędzi w emulatorach tych maszynek znajdziemy i możliwość zapisu filmów, i rewind - pozwalający cofnąć przebieg emulacji i obsługę kodów Pro Action Replay.
W środowisku Win7 x64 emulator daje się odpalić tylko w trybie zgodności z Windows XP SP3.
Renegade (SEGA Enterprises Ltd., 1993), kolejny klon i kolejne potwierdzenie, że tylko wersja na ZX Spectrum może budzić zachwyt:P
