Action Replay codes
- 00D29909
- Infinite Lives (keeps showing 9)
- 00D50C95
- Higher jumps (pressure sensitive. Warning: this code may mess with the game's behavior in general)
- 00D2C0YX
- Keep the timer at X minutes (replace the YX on the code for a number from 00 to 99; the timer will display only the last digit of the entered number, though (e.g. entering 89 will give you 9:00 at the timer). Whenever you enter a 9-ending number (e.g. 09, 19, 29, ..., 99), you'll end up dying after the first minute (due to the 9:59 to 10:00 internal changing on the timer), unless you use the following PAR code to lock the seconds)
- 00D2BFXX
- Keep the timer at [XX + 1] seconds (replace the XX on the code for a number from 00 to 99. Entering 59 will actually advance one minute, so it shouldn't be entered if the previous PAR code is set to show 9:00, or else you'll die within one second)
- 00D297XX
- Zone select (replace the XX on the code for a number from 01 to 05 to go from the second Zone to the last Zone (starting at the first Act); disable the code after starting the level)
- 00D298XX
- Act select (replace the XX on the code for 01 or 02 to go to either the second or the third Act of the given Zone (will start on the first Zone if there is no other Zone specified by the previous PAR code OR by the Level Select cheat); disable the code after starting the level)
