Unlock All Hotels

Start a new game and make it to the high score screen - this can be done through either losing every life or the Down + Button Two stage title screen input. Enter the following name:
B_ 
That B_ is followed by a single space, by the way.

The French version of Hotel Mario doesn't have the underscore available for names, so its equivalent code is:
B- 

Restart Hotel Mario and restore this saved game, and all Hotels will be unlocked for you.

Stage Title Screen Inputs

This isn't technically a cheat, but not many people know about these as A) the game doesn't have a tutorial, and B) it's only listed in the enclosed instruction book, which most don't have and/or read.

On the stage title screens (the ones you have to skip by pressing Button One), hold down Button Two and move the controller in any of these directions:

If you're playing Hotel Mario in an emulator, you'll have to use the mouse for the controller movement. Binding movement to the keyboard won't work.

Special Day Messages

The Philips CD-i has an internal clock which Hotel Mario uses to replace the "HERE WE GO!"/"CHAUD DEVANT!" text with a date-specific message.
Most of these dates are actually based on ranges instead of appearing for one day only.

Both versions of the game - English and French - have unique messages.
This isn't a cheat code, technically, but I have nowhere else to put it.
