Some notable differences from the retail version:

- Debug menus appear in the beginning of the game; this can
sometimes disappear if this isn't your first time playing the disc.
- A mouse cursor appears during the beginning; a mouse can probably
be used to mess with the debug menus.
- Loading screen shows 'Project Eden'; the title screen says 'VIBES.'
- The menus are different from the retail release.
- Some of the sound effects have changed from the retail release.
- The music is mostly different from the retail release.
- The bosses act differently than in the retail release.
- The timing of the attack waves is less precise than the retail
version, and sometimes groups of enemies will appear and disappear
during transitional sections.
- The VMU displays a different animation than the retail version.
- The options on the main menu are different:
PLAY - Same as retail
EXTRA - Play all areas one after the other, like BEYOND mode
in retail, sans options
REPLAY - Shows a replay of your last played game
DEMO - Similar to HOW TO PLAY in retail, but can select
tutorial or short demos from stages 1 to 4
- Sometimes a small debug window flashes at the top right of the screen.
- Some of the graphics in-game are different from the retail version.
- The end-of-level score screen looks different.
- You can continue right where you died, unlike in the retail version.
- There is a unique intro to each Boss in the Boss Rush area which is
not in the retail version. You shoot groups of enemies that
form the name of the boss to earn bonus points.
- There is no music during the Boss Rush.
- The third boss in the Boss Rush is different.
- The final boss is similar to the retail version, but you start in the
center and gradually pan out at each evolutionary stage. The
video footage between each stage is also different.
- There is no ending, but the Boss Rush is labelled as Area 6 and you
are scored separately from Area 5.
- There's a sinister 3D picture on the options scrren.
- VMU saving, just like the retail version, works fine and takes 9 blocks.
