A prototype of Jet Grind Radio (also known as Jet Set Radio) for the Dreamcast.

Notes

  • Compiled about 12 weeks after the initial Japanese retail build.
  • A localization intermediate build, but it has some obvious differences.
  • Occasionally, a red text string appears in the top-left for a fraction of a second, displaying the Exec Loop Time
  • Other times, Draw Loop Time appears in yellow
  • Begins at a debug menu
    • Stage and mission select
    • character select (including opponent)
    • Goto demo hangs the game on a black screen
  • The debug menu can bypass the intro stages/GG gang formation trials, going to the main menu. But this causes things like just having 1 playable character (instead of 3).
