Hey, folks. I tried hacking this wrestling RPG (yeah, I know, I know) to look for a sound test or some kind of debug menu. I couldn't find anything so far... But I did find a handful of undocumented passwords. This game has fantastic music by Hirohiko Takayama (I believe) so I'd love to find some kind of test menu if it exists...
First off, the useful ones:
Lets you view just the cinema scenes (of the whole game??)
Lets you play just the matches (no cinemas.)
"Puffed-up chest" Dunno the effect, maybe makes you strong in battle?
"I'm a kitty-cat. Meoooow!" Dunno the effect, makes you weaker?
The rest of the passwords just give you hidden messages, I think...
"I'm maad! <fume fume>" -> "Don't get so angry at me!"
"July 3 9 1" -> "Take care, Suma-kun!"
"AEIOU..." -> "Yasuko Yasuko Yasuko..."
"R-Z Satsuru R" -> "That's the name of a [motor]bike."
"Sagami Ohno Station street" -> "The offices of Arai."
"AAAA..." -> "Don't be lame!"
"My head is hard!!!" -> "You are PC Genjin."
(Some of the passwords might vary, but the password code treats the 12 or so pages of fonts as the same letter. Eg: "MI" = Dash, "A" = "GA" so the stored passwords' actual text is a little ambiguous.)
