Data Packs are Satellaview 8M Memory Packs which have data meant to be used as expansion for a Data Pack-compatible game.

Data Pack-compatible game cartridges have a resemblence to the BS-X Cartridge itself. The games which were compatible with Data Packs are:

  • Same Game
  • Derby Stallion 96
  • RPG Tsukuru 2
  • Sound Novel Tsukuru
  • Ongaku Tsukuru Kanaderu
  • Joushou Mahjong Tenpai
  • SD Gundam G-NEXT
  • Shigesato Itoi no Bass Tsuri No. 1

For most of these games, Data was distributed via St.GIGA's Satellaview services. Same Game and SD Gundam G-Next had some Data Packs sold as retail in stores. RPG Tsukuru 2, Sound Novel Tsukuru and Ongaku Tsukuru Kanaderu could save user-created data to 8M Memory Packs.

Misc. Notes

RPG Tsukuru 2, Sound Novel Tsukuru and Ongaku Tsukuru Kanaderu apparently have some sort of cross-compatibility with the various data.

On real hardware, there is a way to corrupt a 8M Memory Pack in RPG Tsukuru 2, causing an otherwise rarely seen 'Error 41" message to appear on the BS-X.
