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.

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.
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).
- 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"
- 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.
Tropical Trouble and Frogger Goes Skiing have some unused demos. They can be seen in the video.
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The map is very unpolished, with lots of holes in the collision grid and outdated textures.
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.
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.

Debug Text (PlayStation (US))
The file SLUS_005.06 on the PlayStation (US) version of the game contains debug text..
... ... ... [ "----------------\n" "%jcFROGGER" "%jcCOMPILED: 13:01" "%jcBUILD: 71" "%jc23/09/97" "----------------\n" ]; This build information changed during development, and this was shown upon booting the game on debug builds. Unsure what %jc stood for. One guess is that it centered the text and added a newline character.
