Level Select#
Game Genie code RGST-A6XN (US/EU) or RGTA-A6VL (JP) adds a level select to the options menu.
The levels can be toggled while in the options menu by pressing A or B, and then pressing Start to go to the chosen level. Be careful that pressing B will also toggle the highlighted option.
Some of the levels use letters. They represent the following:
- B = Boss
- T = Teacup (Hidden Level)
- S = Sea (Underwater)
- L = Last (Final Boss)

Unused Teacup Stage#
After using the above level select, three different teacup levels can be accessed (4-T-1, 4-T-2 and 4-T-3). Entering 4-T-2 will load up what appears to be an identical level to the first. When completed, Mickey will be dumped to the side of the second teacup as opposed to the handle of the tea cup. The second teacup level can be entered and completed as usual.

When talking to the Old Mouse, a flashing cursor appears at the end of each sentence in the Japanese version. This flashing cursor was removed in the International version.
Pressing START in the International version allows you to skip the conversation with the Old Mouse and instantly appear inside the castle. Pressing START in Japan version does not allow you to skip the conversation, and you have to watch Mickey destroy the 3 toy soldiers that come out of the castle.

If you have set a HI-SCORE in the Japanese version, wait until the demo plays (stay on the Title Screen for a few seconds), and during the demo, SCORE will have been replaced with HI-SCORE. This text was removed in the International version, so SCORE will always be displayed during the demo.
