ripping sprites from the other smart kids series games

[violetblooded]

i'm looking at the "option_info.chc" file (which i believe contains the "ask mother to help" screen) which tinke says it can unpack
even though when i try to unpack it it doesn't give me anything useable

i was thinking about trying this with a different ds graphics ripper but i dont know any more good ones besides tinke
