Still often blow my camera's dial, and it does help fixing the problem temporarily (probably bad dust sealing so there's dust inside that shorted the dial)
I'm still not sure why you'd blow into a crossbow, though Taihou is probably their resident expert on them. Anything big enough to jam up a crossbow is probably big enough to not be blown free, unlike dust on contacts. You were always better off cleaning those with rubbing alcohol anyways.
When blowing on cartridges, don't blow directly on the contacts. Put a thin fabric between your mouth and the contacts to prevent the water in your breath from damaging the connection points -- the shirt on your back works for this purpose.
I learned the hard way, when my old Yoshi Island cartridge just stopped working. I had to save my lunch's money for like 6 months to buy another one because I didn't want my parents to notice.
There's also the case that yes, you got rid of dust from cartridge contacts? But, what about the dust into the console contacts? Probably you have never done them before and you are always unnecessary putting the cartridge at fault. So make sure to always clean both when the system is failing.
Blowing never works on my old Nintendo 64 cartridges anymore, neither does wetting your finger and using it on the contact area. I have to use my tongue to lick on it, works like a charm every time but tastes kinda "meh".
Is this really OK!?My fighters just ain't coming out and junk - you think it's jammed?GASHAKStill no good, huh...?Teach me!
Ashigara-sensei!!Leave it to me!Ahh... the contacts are bad, see?TAIHOUUUU!When this happens...HNFFFFFFFF!Eh?RJ-senpai...But in actuality, that'll cause the pins to get rusty - it's a no-go!When you're getting rid of dust and dirt, you should use a commercially-available cleaning set!Eh? Eh!?chkkchkkaGASHAKG'CHKKHFFFFFF!When the cartridge's connection is bad, you blow on the pins to get all the dust off...Of course everyone's experienced this, right!HFFFFFF!
PFFHFFFFFFF!Yeah, I don't know a lick about those bowgun kajiggers.chkkchkkaG'CHK
