Ninja Gaiden Trilogy

Ninja Gaiden Trilogy takes the first three games and puts them all in one cartridge. These 16-bit versions feature updated music and minor graphical changes (and the occasional graphic downgrade!).

Unused Music#

Several unused music tracks and sounds are present in the ROM, including the staff roll themes for both Ninja Gaiden Episode II and III (but not for the first game, oddly enough). Pro Action Replay code 818043?? will play any song at the title screen.

Debug Mode#

Located at SNES address $80FF20-80FF23 is a set of 4 debug flags that correspond to joypad buttons. All 4 bytes were set to $00 (disable) in the final version of the game. Use the following codes to toggle the flags on again:

DFE4-3DD7
DFE4-3D07
DFE4-3D67
DFE4-3DA7

80FF2001
80FF2101
80FF2201
80FF2301

80FF20 - Y button#

If you don't hold Y when the game boots, CPU usage meter is enabled (0x80 set in 7E0FF0). It appears as a thin horizontal line.

80FF21 - B button#

If you don't hold B when the game boots, freeze frame is enabled (bit 0x80 set in 7E0FF1). At any time, press Start to freeze the current frame. Press Start again to resume.

80FF22 - A button#

Hold A during bootup to set disable collision detection (bit 0x80 set in 7E08E6). Then, bit 0x80 is set in 7E08E3 (Ninja Gaiden), 7E08E4 (Ninja Gaiden Episode II), and 7E08E5 (Ninja Gaiden Episode III).

80FF23 - X button#

Holding the X button when the game boots sets bit 0x80 in 7E08E8. In Ninja Gaiden Episode III, debug info is displayed in the upper left corner of the screen at all times.

A check for this memory address and bit also exists in Ninja Gaiden Episode II, but the branch distance after the check is $00, suggesting that the debugging function was removed.

Ninja Gaiden Episode II Broken Sound Test?#

This needs some investigation. Discuss ideas and findings on the talk page.

The button code for the NES version is also the same here. But for some reason, the sound test menu automatically exits after a few seconds, and it doesn't seem possible to play a song/effect even in the time allowed. Is it broken?

Credits#

Upon completing a game, the player is returned to the main menu; however, the credits that were supposed to appear at this point are still in the ROM. They were likely just cut-and-pasted from the original games.

The credits for Ninja Gaiden Episode III are present as well, but because of how words are stored/loaded in that game, only fragments of the text are visible in the game's data.
