Just did up a TAS for the first
D-Pad Hero game. There definitely seems to be unanticipated bugs in this game, that allowed the brute forcing script to run faster than expected, without the game counting button press errors.
http://caitsith2.com/tas/dpadhero.zip
The following code was run, only during the song. Once the song was completed, the script was stopped. It only had to be run four times.
-- D-Pad Hero game play lua bot
-- created by CaitSith2.
-- Just a simple bruteforce every input possible. A & B are never pushed at the same time
-- in the music chart, so, we alternate between Just A, A + directionals,
-- Just B, B + directionals, and nothing.
-- If button pressed increments the error count, then we reload, otherwise we keep it.
-- I was expecting this TAS to take much longer to complete, but because of
-- game programming errors, it went a little faster, as it accepted more input. :)
