This game has hidden development-related text.
Vib-Ribbon is a graphically simplistic, but very challenging, rhythm game where Vibri must get through an obstacle course generated by sound waves.
Spread out throughout the executable multiple times are these simple strings:
Info: status=%d, type=%d, size=%d Analog: Left(%3d,%3d), Right(%3d,%3d) CONTROL =
There's also text for a sound test at 0x40D4 in MAIN_G.EXE:
OFF MAIN PSJ MODE SELECT UNKNOWN MODE SELECT MODE SPEED SELECT CD CHANGE TRK SELECT ALERT VIB CD IN ALERT AUDIO CD IN CD CHECK OPTION PSJ HISCORE UNKNOWN HISCORE CLEAR AGAIN AGAIN SELECT DONE
And these strings at 0x43CC, which might have been for a level editor:
Selector Type Pattern Index Distribution Index Road Part Period Select Period Effect Parameter Effect Duration Send Random Effect Send Reverse Effect Send Screw Effect Send Camera Effect distribution MemPtr: file %s not found
