Unused Chart Data

Taiko no Tatsujin 4 has 177 chart files, which are used for the game's 48 songs. Of these 177, 33 have branch sections that are otherwise unreachable, though they're mostly the same as what is seen, placeholders, or holdovers from the previous game. They are as follows:

• Chart 041 - FEEL_H (Feel fine! - Hard/Muzukashii)

Different Unseen Branches

The following charts have unused or otherwise unreachable branch areas that differ slightly from what is seen:

Chart 017 - CUTIE_H

Cutie honey‍ '​s Hard/Muzukashii chart. While it has no branch transitions, both Advanced and Master branch areas are filled in; both are completely different from any of the used charts, having more sections that differ between the 1P and 2P sides, and even feature Balloon notes without associated parameters at measures 33, 35, 37, and 38. This data can also be found in Chart 018, CUTIE_M, which is the song's Donderful! chart.

A modified conversion of the Hard chart to the .tja format, which can be read by programs like TJAPlayer3, can be downloaded below. Due to the aforementioned valueless Balloon notes, as well as the lack of branch quotas, artificial values have been added in.

• The Advanced Branch has an additional Small Don note at beat 1 of measures 9 and 13, while the Master branch has two additional notes, at beats 0.75 and 1.
• The Master branch has an additional Small Don note at beat 1.75 of measures 10 and 14.

Chart 072 - KATTE_H

Katte ni Sinbad‍ '​s Hard/Muzukashii chart. While the first branch transition happens at measure 15, both Advanced and Master branches are populated before it. The latter is identical to what is seen, but the former has a few differences from measures 4 to 6:

• The notes at measure 5 are shifted a 16th earlier in the unused variation, causing one to appear at the end of measure 4:

• The Small Don notes at measure 6 are organized differently: rather than being at beats 0.5, 1.5 and 2, they are at beats 0, 1, and 1.75.

Unused Sounds

Stored alongside Don-chan/Kat-chan's voice clips are several unused voice clips of them announcing individual song, battle round and total battle results, respectively. It's worth noting that while they do announce individual song results starting from Taiko no Tatsujin 7, they never announce battle round and total battle results outside of the console games.
