Jazz Jackrabbit Version Differences

There have been at least 5 different fullgame releases of Jazz Jackrabbit. All releases have bugs and oddities in levels, none is perfect.

Summaries of the releases:

I (Simon N.) recommend the good 1.2 for casual play, and I recommend Jazz 1.0 for speedrunning episodes 1-6.

Jazz 1.3 got re-released by Good Old Games in November 2017. There is no clear way to fix the issues in GoG's 1.3 release, mainly the almost-impassable Orbitus 2. Ideas:

The following table shows all the version differences I know.

Jazz Jackrabbit 1.0 Jazz 1.1 Jazz Jackrabbit, good 1.2 Jazz Jackrabbit, bad 1.2 Jazz Jackrabbit 1.3
Disk Floppy Floppy CD CD CD
Version printed by JAZZ.EXE before reaching main menu none none 1.2 -- the good and bad 1.2 have byte-for-byte identical .EXEs 1.2 -- the good and bad 1.2 have byte-for-byte identical .EXEs 1.3
Version reported by HELPME.EXE in the top-right corner 1.0 1.1 1.1 -- the good and bad 1.2 have identical outdated manuals 1.1 -- the good and bad 1.2 have identical outdated manuals 1.3
Intro cutscene Jazz points with gun on black background Jazz cosplays as 3 superheroes Jazz cosplays as 3 superheroes. But I've heard that some CD version had the gun/black intro? Fullgame: Jazz cosplays as 3 superheroes. Demo: Jazz points with gun on black background.
Main menu look Normal menu Normal menu Normal menu Normal except during winter, then Jazz will wear a santa coat and snow will fall
Cheat prefix P, backspace P, backspace, DD P, backspace P, backspace P, backspace
Apology mode P, backspace, APOGEE n/a n/a n/a n/a
Birdshot bullet size small ? (presumably small) large large large
Episodes 1-6 1-6, A-C, Z (bonus levels) 1-6, A-C, Z (bonus levels) 1-6, A-C, X (Holiday Hare '94), Z (bonus levels)
Incompleteable levels or almost-incompleteable levels None, all levels are good Marbelara Secret Tubelectric 2, Marbelara Secret Orbitus 2
Tubelectric 2, first room Hidden spring Visible spring No spring at all. To reach the top tube, run into the right tube at full speed, then, as soon as the right tube pushes you leftwards, immediately press and hold down and jump and release right. (You will jump off the floor at the right tube's ejection speed, making that jump very high. Holding down is necessary to jump as early as possible.) Hidden spring
Tubelectric 2, end Short Long: The exit sign from 1.0 is replaced in 1.2 with a checkpoint, followed by a zig-zagging downward section surrounded by yellow and orange square bricks. You get a shield and a bird, then travel through a pipe to the exit. Short Short
Medivo 1 airboard ditch Works Broken Broken Broken
Ordering information after episode 1 One advertizement screen after "Let's not keep her waiting." This is in the fullgame release because you could order episodes 1-3 and episodes 4-6 separately. none none none
Orbitus 1 airboard ditch Works Works Broken -- but that keeps the level solvable because bouncy floors are completely broken, they behave like air Works
Orbitus 2 Fairly easy, can fall through cracks in bouncy floors Fairly easy, can fall through cracks in bouncy floors Requires a bounce off the bouncy wall because bouncy floors are completely broken, they behave like air Almost impassable without tool assistance. Bouncy floors have a huge trigger area, sucking Jazz upwards, away from the intended route. Even with slow-motion, this is excruciatingly hard. Cheat for an airboard (P, backspace, CSTRIKE) or copy MaxStrike's fix into Jazz 1.3.
Turtemple 2 airboard ditch Works Works Broken Broken
Marbelara Secret Passable via hidden spring Incompleteable due to missing spring. Workaround: Cheat for an airboard (P, backspace, CSTRIKE), bypass the pillar, enter the cheat again to lose the airboard. Incompleteable due to missing spring. Workaround: Cheat for an airboard (P, backspace, CSTRIKE), bypass the pillar, enter the cheat again to lose the airboard. Passable via hidden spring
Dreempipes fuel raising/lowering speed Slow: In the final room of Dreempipes 1, you can skip the first red switch on the right and instead swim immediately to the next red switch on the left. If you shoot the Dreempipes 2 speed shoes through the wall from the right, you won't have to hit red switches and can keep the speed shoes until the exit. Fast water raising/lowering Fast water raising/lowering Fast water raising/lowering
Pezrock 2 airboard ditch Works Works Broken Broken
Battleships airboard ditches Both the Battleships 1 and the Battleships 2 airboard ditch work in 1.0, in 1.1, in both 1.2s, and in 1.3. Battleships Secret correctly has no airboard ditch in any version.
Bonus stage music End-of-episode music End-of-episode music End-of-episode music Fullgame: End-of-episode music. Demo: Exoticus music.
Jazz Jackrabbit 1.0 JJ 1.1 Jazz Jackrabbit, good 1.2 Jazz Jackrabbit, bad 1.2 Jazz Jackrabbit 1.3

The CD releases have episodes A-Z. The good 1.2 had slightly harder episodes A-C than the bad 1.2 and the 1.3. Especially Deserto 2 is very hard in the good 1.2. Here are all A-C differences that I know.

Jazz Jackrabbit, good 1.2 Jazz Jackrabbit, bad 1.2 and 1.3
Raneforus 2 airboard ditch Works in all 3 CD releases, even though the TAS notes claim that it's broken in 1.3.
Ceramicus 1, after 1st patch of carrots High pole, tricky to jump over, but not too hard Pole is one tile lower than in good 1.2, it's easier to jump.
Ceramicus 1, before 2nd patch of carrots 3 flying springboards that you must evade, otherwise they'll bounce you back to where you came from No springboards to bounce you back
Ceramicus 1, near the end A moving springboard moves inside a tunnel, directly below a ceiling. That springboard gets you permanently stuck in the ceiling. Solid platform, you can't get stuck
Deserto 2 No carrots anywhere. On Medium/Hard/Turbo, this is is the hardest level in the game. Shooting the checkpoint is disadvantageous, then you can't recollect the 4-shield after dying. 5 patches with 2 carrots each throughout the level. Level has average difficulty.
Lagunicus Boss Select Blaster to fire Toasters, select Toaster to fire RF-Missiles, select RF-Missile to fire Launchers, select Launcher to fire single birdshots that bounce and sound like Launchers. TNT functions normally. All 5 weapons function normally.

See also the great TAS notes by Ilari, Mothrayas, and slamo. They have lots of extra info, even if the list of version differences is not as comprehensive as mine above.

Thanks
