Paca Paca Passion is Produce's first foray into the rhythm game genre. It involves four members of a band playing songs and avoiding having towers of blocks that pierce the screen below them.
Upon merging both of the second graphics ROMs (ppp1rom1l.7 and ppp1rom1u.10) and verifying offset 0x209008, it's possible to see a leftover graphic from a location test version of the game.
The text roughly translates to "Thank you for your cooperation in the location test!".
Found within the strings of the How to Play screen (offset 0x283C4 upon merging the program ROMs ppp1vera.2l and ppp1vera.2p), which is seen in the attract sequence and upon selecting Training mode, is a completely unused English translation for it. Note that the game was never released outside of Japan.
This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Is it possible to access this?
Upon merging both of the program ROMs, it's also possible to view several text strings from unseen operator menu functions, as well as some from a debug menu:
