A prototype of Jet Grind 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).
