Active since 1997, SMS Power is an international force of enthusiasts interested in the following gaming/computer systems:
- Sega Master System (SMS) / Sega Mark III (MK3)
- Sega Game Gear (GG)
- Sega Game 1000 (SG-1000)
- Sega Computer 3000 (SC-3000)
- Sega Super Control Station (SF-7000)
- Othello Multivision (OMV) (SG-1000 clone)
And their regional variants (Korean Samsung Gam*Boy, Taiwanese Aaronix consoles, etc.). All generally referred to as "Sega 8-bit" systems, being 8-bit Z80 CPU based Sega systems.
SMSPower aims to:
- Discuss, gather, publish and preserve historical facts, data and knowledge related to those systems.
- Develop Sega 8-bit interest and enjoyment around the world.
This site was founded at the end of March 1997, first under the name "SMS Camp". It later evolved into a generic emulation site called "Emulation Camp" then split, went back into focus and was renamed to "SMS Power!" in 1999. Many people have joined the community since then and are working hard in order to make this site and our projects a reality.
