Oldskool was a console cracking group, active on the Nintendo GameBoy Color (GBC), SNES and the Sega Mega Drive. There used to be a homepage but sadly it was never archived on the WayBack Machine.
The june 1996 release WildLoad95 v1.0 listed Fazwonga, Creep, Terminator, Agel, Turrican, Kingpin, CQBS, Princip, Slaver, Ironcode, Mr. Z, Healon, Skyblazer, Interphase, Digital Messiah, Hero Zero, Lazy Lizard, Green Legend, Wild and Whiz as normal members, and Glue, Landy, Trilili, Jedi, Rip, Yoshi, TMB and Uxorious as members of the 'internet team' at that time.
The late march 1999 nfo file for Shanghai Pocket v1.1 (no cracktro, hence no entry here) listed Fazwonga, Creep, Blob, CQBS, Hudson Hawk, Turrican, Amptor and Gilligan as members at that time. An august nfo then revealed Blob, Turrican and Gilligan had disappeared, while McFly was a new addition.
A january 2001 nfo file had added Duz as a member, while Hudson Hawk was gone from the list.
