Frogger, he's back! Also pretty much the last classic-style Frogger game until Frogger Returns and Frogger: Hyper Arcade Edition (and either the best or worst depending on who you ask). It is also absolutely brutal in difficulty, especially when compared to its immediate sequel.

To do: Document unused code / debug features. Further explore prototype differences. Document the differences between _WIN95 and normal. (Assets and gameplay other things like menus) Document the raccoon's unused animations, and the fact that it uses the walk animation underwater. Document the prototype demo keypress differences. (Also check out assets. Talk about Environment Polys (Green Balloon)

Prototype Info

Prerelease Info

Unconfirmed The content under this sub-page is not publicly verifiable.

Prototype Content found on prototype builds of the game.

Unused Music

This track has no identified name, but the game's source code suggests it was for the cut Ruins Zone.

This track originally was meant to play when the jungle zone was completed. Because the credits play when you complete the jungle zone, this track goes unused.

Version Differences

There are quite a few differences between the different versions.

• The Japanese PSX release has a setting option where you could start the game with their selected lives (3, 5, 7).

International	Japan

• The Japanese PSX release uses a different font for the text and the menu selection was wider. and it also swapped the button icons to "O" and "X"

International	Japan

• In the Japanese PSX version, the Music and Sound volume were located in the sound options menu, as well as the save and load option and high scores are located in the respective options menus.

• It also has a difficulty selection (easy, hard). Easy mode disables timeout deaths.

• The PC version starts the player with 5 lives, while all of the other PS1 versions start the player with 3 lives.

• The US PSX version runs at 30FPS, but all other known versions of the game (besides the prototype) run at 25FPS, including the PC version.

• Playstation versions have a short drum beat which plays when loading a map, but this doesn't play on the PC version.

• Various sounds are pitched differently on PC than they are on PSX. It might be due to the framerate differing, but this has not been confirmed.

• Bugs have a slight glow around them in the PSX versions, however on the PC version there's a "bubble" sprite.

Unused Palette Files

The PC version contains a .PAL (Color Palette) file for each level, along with a palette named "OPTIONS.PAL". These files are believed to be unused because if they are corrupted, there are no visible changes.

Developer Levels

ISLAND.MAP

This file was found in the PSX build. It was created by developer Tim Closs, it was used to test many different things.

One of the main things it was used to test was movement and slopes.

It contains a mud-pit which causes the player to bounce. This behavior is not seen in the retail game.

The map is very unpolished, with lots of holes in the collision grid and outdated textures.

QB.MAP

This odd unused map is likely designed and named after QBert.

The map has no textures, only vertex coloring.

Words cannot describe how strange this map is.

Hidden Developer Comment

In each map file, the comment is:

Maybe this time it'll all work fine...

Out of Bounds Models

Retro Level 5

This model matches the crocodile head model used as an enemy in this zone. However, this is part of the level geometry.

Bang Bang Barrel

<

This flag looks identical to the flags used in the multiplayer stages as checkpoints. However, it is part of the level geometry, and not animated.

Boom Boom Barrel

This box model was accidentally put into the map instead of the entity it represents. The entity that was supposed to be placed here would kill Frogger when he touched it, and not display in-game. However, the 3D model was placed there instead.

Unpublished Cheats

Originally, several cheats were published on the Frogger website. Additionally, there is an extra cheat which was not published.

PC: NO MORE TIMEOUT DEATHS PLEASE

When the timer reaches 0, it will remain at zero, but the player will continue playing as normal instead of dying.

It is unknown why this cheat-code was not published.
