Snow Bros. (NES)

Debug Leftovers#

The Object Test can be accessed by setting the main routine index ($0353) to value $02. Using the D-Pad buttons on both controllers, you can change the object, its animation phase, or CHR ROM banks. Press A to show the object onscreen. Some value combinations may crash the program due to lack of limit checking.

The main cheat menu sits at CPU address $A41E (US) or $A413 (Japan) in bank 6. There is no display, but input is working. On Controller 1, use the D-Pad to change sound test/level select index, press A to play music/sounds, press B to stop it. Press Start to exit to the Object Test mode (press Start one more time to play from the selected level), hold A on controller 2 and press Start on controller 1 in the Object Test mode to enter the Time Mode menu.

Pressing Select should update and load the demo record table (enters the Object Mode first, then exit it to play a demo of the selected level), but in the final version it will crash the game. Game Genie code GEUXGKSO will fix this. Demo index is selected with Up/Down on Controller 2.

Regional Differences#

To do:
There's a bit more than this, including various graphical changes.

Time Mode#

All regional versions have a special "Time Mode" game. In the Japanese version, you can select which mode to play just by pressing Select on the title screen.

The US and European versions require a much more complex button sequence to enable it: Up (×2), Right (×8), Down (×2), Left (×8), then press A or Start.

Japan/US

Europe

The European version also fixed the "NOMAL" typo.

Staff Roll#

The Japanese version's staff roll is completely in Japanese hiragana, save for the "SPECIAL THANKS", "DIRECTOR", and "PRESENTED BY TOA PLAN" titles.
