Introduction - Mission Statement
We are interested in those gaming consoles/home 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)
All generally refered to as "Sega 8-bit" systems, being 8-bit Z80 CPU based Sega systems. The inclusion of Othello Multivision here is because this console (only released in Japan) is a Sega SG-1000 compatible clone.
Our project:
- Develop Sega 8-bit interest and enjoyment around the world.
- Gather and publish historical facts, data and knowledge related to those systems.
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 our community since then and are working hard in order to make this site and our projects a reality.
Our first step is to have all Sega 8-bit software (games) data archived, sorted out and released to the public. Archiving software data (often referred as "dumping a ROM", although this terminology doesn't apply to tapes, floppy disks and non-ROM based cartridges) is important because some of this old software is very difficult to find nowadays. Some media are also prone to being damaged and might disappear forever if they are not preserved now.
One nice effect of having software archived is that you can use and enjoy it by the means of a software emulator or a special writable cartridge/device. This is the meat of enjoyment for many people, who just wish to enjoy games they played in their childhood. However, please primarily think about our work as historical preservation.
In addition to dumping, which is becoming an easier process nowadays, lots of work is put into verifying and labelling new and existing data, and comparing variations that may exist between different countries or rereleases. This is a tedious job, often requiring deep knowledge of the games and analysis based on the original box, game media, documentation, or reverse engineering program code. Only this work can allow us to have a clean and definitive listing of games one day.
To achieve this, we have many questions to answer, problems to solve, hardware to analyze or construct, software to locate and obtain from all around the world, etc. Many people participated by donating their time, knowledge, software or money. They are listed on the contributors page. As this project is ongoing, your contributions still are, and always will be, welcome.
Second step for SMS Power is to transform into a big Sega 8-bit museum, providing a definitive resource for:
- 1. Games.
Including, but not limited to: worldwide release information, ROM dumps, box and media scans, manuals, screenshots, reviews, cheats, technical information, credits, soundtracks.
- 2. Hardware.
Including, but not limited to: worldwide release information, pictures, technical specifications, possible hacks.
- 3. Media.
Scans, movies, and photos of advertisements, magazines and related goodies.
SMS Power aims to be a growing community. Lots of fun and knowledge is being shared and discussed daily in our forums. Please visit and register there!

And of course all contributors.

The order of this list does not necessary reflect the amount of involvement and work for SMS Power. Several members are not around any more after all these years, but their past and invaluable help is not to be forgotten. Thank you all!
And a special thanks goes to Andrew Lindsay for having designed his early homemade copier and founding the "SMS Preservation Society", from which I started getting interested in gathering cartridges and dumping. It was in 1996.
How to support SMS Power?
- 1. Any Sega 8-bit hardware/software you would like to donate are welcome, so are money donations (all useful to buy cartridges and hardware). Anything is helpful.
- 2. Your involvement is greatly appreciated. We are always looking for programmers, software and hardware hackers, artists, musicians, translators, collectors, web developers (PHP/database stuff) or any kind of Sega freaks and knowledgeable people. If you have motivation, time and a brain, there is always stuff to do to help us!
- 3. If you are an original Sega 8-bit developer, any kind of information, archives or hardware you may have left is our joy. Let us dream.
We need your support in order to continue!

Okamoto Ayako no Match Play Golf (OMV), Uranai Angel (SC), Doki Doki Penguin Land [Proto] (SMS/JP) Posted Sunday, January 31 by Bock
Today some curious oldies for our Japanese friends.


Okamoto Ayako no Match Play Golf for the Othello MultiVision (岡本綾子のマッチプレイゴルフ), the Tsukuda system compatible with SG-1000, featuring once's Japan favorite's Ayako Okamoto golf champion.


Uranai Angel Cutie for the SG-1000/SC-3000 (占いエンゼルキューティー), a keyboard software where a naked angel tells you your fortune. Being totally in Japanese, this is practically impossible to use for people who don't understand a little of it. Just inputing your birthdate is enough of a challenge (Showa era is 1926–1989 so you have to subtract 1926 from your birth date and then...). If you used this in 1984 please tell us if the software was right in predicting your future.


Last for today, a Prototype of Doki Doki Penguin Land - Uchuu Daibouken for the Master System (どきどき ペンギンランド 宇宙大冒険), everyone's favorite penguin in a puzzle-action hybrid space adventure, cute and worth playing. And the game also feature a level editor. This is a Japanese cartridge prototype, exact differences yet unknown.

Suho Cheonsa (SMS/KR), Maou Golvellius [Proto] (SMS/JP), Montezuma's Revenge [Proto] (SMS/US) Posted Thursday, December 24 by Bock
Hi kids !!!
Did you write that letter to request the new roms you wanted this year? Oh oh I see you did not. You kids don't write enough those days I can tell; you should be writing more letters and playing less video games.

Some fancy game I got for you tonight!
Suho Cheonsa for the Samsung Gam*Boy / Sega Master System (수호천사), an original Korean breakout-style game by Open Corp. It is quite an elusive game, although a version of it it was also included in the also elusive 4 Pak All Action compilation released by HES by Australia (which feature other games from Open).
What is this face you're making boy? Sure it's not that new Alex Kidd game, but in my time all we got from santa was a wooden 8x8x8 pixels cube and a blocky orange. Surely this must be real exotic.

And I've got some prototypes from my secret pocket!

Maou Golvellius [Proto] for the Sega Master System (魔王ゴルベリアス), the good old action-adventure classic by Compile. Quite a symbolic thing, as prototype of Japanese games are really hard to come by. Can you tell the difference?

Montezuma's Revenge - Featuring Panama Joe [Proto] for the Sega Master System, also quite a classic but from the west. This unforgiving arcade exploration title created by Robert Jaeger is a really fun play for adventurers - try a bite on the easy levels and enjoy dying and learning the later ones. It is also apparently one of the earliest platforming game (first version was created in 1984)

See you soon!

( Don't forget to keep those ZIP files under the tree and only open them tomorrow morning. )

Game Gear country variations Posted Sunday, November 8 by Bock
I've been sorting out through some common country variations which were dumped last year, trying to release them at a decent rate from now. We've got 6 new Game Gear ROMs here. Nothing truly exciting, mainly aiming for completeness.

Cool Spot for the Game Gear, European version (previously released was US version).

Bram Stoker's Dracula for the Game Gear, US version (previously released was European version).

Earthworm Jim for the Game Gear, European version (previously released was US version).

Fatal Fury Special for the Game Gear, European version (previously released was US version).

Out Run for the Game Gear, Export - US/European - version (previously released was Japanese version).

Shanghai II [v1] for the Game Gear (上海II). This is "version 1" extracted from the Meisaku Collection re-release of the game, as opposed to the original "version 0".

As a side note, Maxim has been recently working on a pretty major reoverhaul of the site. We have no date yet, but we hope it'll spawn a new era of collaboratively assembling and organizing the information the community has developed in the past years. Stay tuned!

Home Basic (SC/JP), Chouon Senshi Borgman [Proto] (SMS/JP), Alien 3 (GG/JP), Ecco the Dolphin (GG) Posted Monday, September 14 by Bock
Tada! Happy new roms to prepare you for end of summer!

1985's Home Basic for the SC-3000 (ホームベージック) is a revamped version of Sega Basic, packaged with three demonstration software: a shooting game, a text-based calculator program and a sprite pattern editor. I am actually unsure about how to save the patterns which makes it of cute dubious use (there is maybe a way, I don't have a manual for this cartridge). Other than that, Basic is your way to freedom and creativity. Maybe try to make something for it ?

1988's Chouon Senshi Borgman [Proto] for the Master System (超音戦士 ボーグマン), in a Japanese prototype version. Known in the west as Cyborg Hunter, this competent and charmful action game with a pinch of adventure, in the vein of Zillion, is quite a classic. This prototype was obtained from an old stash of Mark III prototypes from an unknown source, not sure of the differences with final version.

1992's Alien³ for the Game Gear (エイリアン3), in its Japanese release, an unsuspected decent action game.

Last and least, 1993's Ecco the Dolphin for the Game Gear - why you ask? As it turn out, the version previously available on the internet, circa 1996-ish, has a bit of data wrong that is fixed here. I confirmed this one on both US and European releases. Note however that I'm not 100% sure that isn't a cartridge around with the so-called incorrect bit, if one eventually shows up the information will be corrected, but for now it seems statistically plausible that there is only one US/EU version of the game, and you have it now.

Ttoriui Moheom (SMS/KR), Wonder Boy in Monster Land [Proto] (SMS) Posted Monday, July 20 by Bock
Hello all,

Two new releases today!


The first is a Korean dump that was gracefully donated by Blue/Nights who previously gave us two other Korean dumps (Hwarang-ui Geom and Super Boy 4).
Ttoriui Moheom for the Master System / Samsung Gam*Boy, Korean version of My Hero. This is essentially a simple hack of Seishun Scandal, the original Japanese version, where the Sega Mark III logo has been replaced with Korean text (reading, anyone?). My Hero is always worth playing. Skills required.


Second we have a Wonder Boy in Monster Land [Proto] for the Master System, a prototype for grand Westone classic. This is part of the recently discovered Sega of America stash. I don't know yet exactly what are the difference in this ROM. Because the Japanese version is essentially harder than the Western release, there might be left-over making it an "intermediate" version of the game. Experts please report!

Columns [Proto], Gain Ground [Proto], James "Buster" Douglas Knockout Boxing [Proto] Posted Sunday, June 28 by Bock
From below mentioned mini stash of treasure, we have new prototypes up today!


First we have good old classic Columns [Proto] for the Master System, in all its austere cuteness, embedding a solid 2-players mode. Note sure what exactly is different in this prototype, but the title screen and menu text are clearly different.


Gain Ground [Proto] for the Master System, a rather overlooked good game. Overhead action of surgical precision, a drop of strategy and 2-players simultaenous mode as well. Read more: Gain Ground on Wikipedia !


Last but least, we have a James "Buster" Douglas Knockout Boxing [Proto] for the Master System. An uncommon US release, reskinned version of the decent Heavy Weight Champ. The only difference with this prototype and the final version are some ROM header settings, meaning there's no actual gameplay difference with final version.

Enjoy!
