This rom was kind of a tough case to crack for me. Wierd mapper too. 
It had quite a bit of rle encoding and it was my first encounter with tategaki (Japanese Vertical Text).
I opted to get rid of it since it said multiplication was ovious you had to multiply 
to play the game anyway. 
Everyhing is done save for some graphical bug in the fourth mini games bonus screen.
But it's nothing that takes from the gameplay.
You are more than welcome to fix it, if it really bothers that much.
Enjoy the game!
