Ninja Gaiden Trilogy

Ninja Gaiden Trilogy
Also known as: Ninja Ryukenden Tomoe (JP) Developer: Tecmo Publisher: Tecmo Platform: SNES Released in JP: August 11, 1995 Released in US: August 10, 1995 This game has unused music. This game has unused text. This game has debugging material.

Ninja Gaiden Trilogy is pretty much the first three games in the series with updated music and very minor graphic updates (and the occasional graphic downgrade!), all in one cartridge.

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:

Game Genie	Pro Action Replay
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.
