Sorry that I am unable to reply your post in such a long time, main reason being I am not so active on sgf anymore, and not so many people actually reply into this forum.
I didn't have that kinda experience before, but iluma tornado arcade really sucks. Other big big arcades use english they use chinese. Next time dun play there, go a bit further down to vivo play 3dx+. Dun understand chinese? dun play. Btw it's true you can use 3dx cards on the machine.
Talking about 3DX+, try not to buy the R35. No dressup is allowed according to the game system. I am playing the 1970 GTR, quite good actually, worth to try.
