I played this when it first came out as a kid. then replayed it back in 2005 when i was rich and living in a high rise (i am now poor and back with the parents). I never thought it needed a balance hack since it was beatable as a kid and i beat it as an adult.
Im a huge PCengine TUrbografx fanboy so that may have something to do with it.
I am currently trying to do a machine translation myself, so I look up to this project a lot. BTW just because this is a machine translation does not mean the guy left it in Engrish, he re edited the text to make sense and make the game playable till the end.
