The BS system was a addon for the Super Nintendo Entertainment System [SNES]/Super Famicom in Japan, the system allowed users to download and play "upgraded" or updated SNES/Super Famicom titles.
The system worked by attaching a base unit to your console which could then connect to the internet via a special "Sattelview" dish, the system required the user to be subscribed to the "St. GIGA satellite radio station", users could then download the selected games between the select hours of 4pm to 7pm.

Here is a quick graph showing how the system worked:



After being downloaded the games would be saved to a flash cart similar to that of todays flash carts avaliable for systems such as the GameBoy Advance. This flash cart came included only with the "Deluxe System", the console itself contained a meagre 512k of memory so for some larger games this was not enough. The console used an adapter for the flash cart since the smaller carts that were used in the production were cheaper to make.

The titles released on the BS system fell into many different categories:

* exclusive releases, new entries in established series available only on the BS-X; indeed they are still exclusive, as none have ever been rereleased as yet.
* rereleases, exact replicas of the cartridge data of normal Super Famicom games, except in a format for broadcast over the satellite
* remakes of previous Famicom games, often hugely enhanced, as in the cases of BS Zelda and BS Mario ExciteBike
* remixed Super Famicom titles were occasionally released, as in the case of BS Zelda: Kodai no Sekiban
* original creations; there were a handful of BS-X games that were not part of any established series.

Note: If I have made any errors, repeat my self or spelling mistakes please tell me, also I do not believe my list of BS games is complete if someone could tell me of any that are perhaps missing? I will be updating this post later with more information and screenshots of the BS titles that are avaliable on ROM.
Ta to Teflon for the BIOS, Eric and Sonicblur for the missing games.

You just stole those images from Wikipedia and google, not that I blame you... haha. Satellaview was probably more succesful then N64DD.

I see Special Tee Shot is missing from your list. It's a rather fun mini-golf game that was eventally turned into Kirby's Dream Course.
If I recall correctly, ZSNES can't run it properly, although SNES9x seems to run it fine.

Also, the BSX Chrono Trigger titles are missing from your list.

Just as an FYI, the BIOS for this thing has been dumped, in case you want to fuck around with it. Only works in SNES9X.

F-Zero 2

EDIT: F-Zero "2"...

First post updated.

Ta to those who contributed, going to do a bit more on BS Fire Emblem, BS F Zero and the BS Zelda's later.

BS Fire Emblem

This was no more than a map pack designed around the Fire Emblem theme, the game itself lacked the battle scenes that FE usually has when characters entered battle and rather instead had life bars appear when characters are in battle:

Each map gave you a limited amount of units you could use for each chapter, ranging from Akaneia Senki 1 which gave you one Paladin, two Armour Knights, A Shaman, a Priest and a Archer to use. The games themselves were based off the sprite set used in Fire Emblem 3: Mystery of the Emblem (A combanation of FE1: The Dark Dragon and Sword Of Light and Fire Emblem Gaiden), the games were all one chapter long with a different set of character in each level, except for Akaneia Senki 4 which had the Priest from Akaneia Senki 1 re-appear.



BS F Zero "2":

F Zero 2 (Or BS F Zero Grand Prix 2) was a remix of the original F Zero for the SNES, it featured four cars from the original (with updated sprites) and one class and one set of tracks to begin with.
The four tracks in the "Ace Leauge" were:
Mute City IV

Big Blue II

Sand Storm I

Silence II

Sand Storm II


(I know this isn't much but there wasn't much else to say about them =/)

Personal Note: Could some please translate the character names for me? I want to get hold of them for the FE website I run? I know its a bit cheeky but it would really be appreciated, thank you.
Akaneia Senki 1 - Palace Kanraku Characters:






Akaneia Senki 2 - Akai Ryuuki Shi Characters:






Akaneia Senki 3 - Seigi no Tozokudan




Akaneia Senki 4 - Hajimari no Toki[/u]

Also, first person to say "Bandai" gets denutted. Although it seems like that little bit of misinformation is starting to diminish.

Your picture link for Big Blue II is wrong.
