Regional Differences

To do:
Add further details on the regional differences, do closer analysis on unreleased Edd the Duck.

For reasons unfathomable to the human mind, We're Backǃ A Dinosaur's Story was officially modified and re-released three different times (planned to be four), being altered for every country it was released in. Baby T-Rex is the original version of the game, released in most of Europe, We're Backǃ was the US version (also released in parts of Europe), Agro Soar was for Australia, and Bamse was released in Sweden.

Each version only replaces the main character and alters the storyline, and occasionally swaps the music cues around. All other visual elements remain intact, meaning each one inexplicably takes place in the dinosaur age.

All versions have the same set of 5 cheat codes to enable various features like infinite lives/projectiles/time, invulnerability, and Level Select.

There are at least two more cheats that have different behaviors between each of the regional versions: Up, B, A, Down, B, A and Left, A, Left, B, Left. Both are meant to display the various sets of the game's cutscenes. However, the only version these cheats actually work on is the Australian one.

  • Agro Soar has only the first of these two cheats, the second is not present. Upon entering, it will show you most of the in-game cutscenes as well as the cutscenes for the ending, when you press Start at the title screen.
  • Bamse has both of these cheats in the data and checks for them. However, due to a dumb RET patch to the handler which should call the actual cutscene displaying routine, both of these cheats cause the game to hang if you press Start at the title screen. Also, the cutscene displaying routine can show only the very last screen of the ending, there is no coding for displaying cutscenes in sequence. Game Genie code 002-7EF-C4D will restore the broken functionality.
  • We're Backǃ has a much more complicated cutscenes display routine at 01:7DDF in the ROM, which has different paths for both cheats: the first one should've shown all the cutscenes in sequence just like the Australian version, the second one should show only the last ending screen. Unfortunately, the caller handler for this routine is completely removed and dummied out, returning control to the title screen and not doing anything with the cheat flags, which causes a permanent loop back to the title screen when pressing Start, rendering the game unplayable if cheats are enabled.


The ending for all four versions are completely different from one another.
