SMB pack is just POPStarter in debug mode with memory card files. Obviously you're already doing that.
But you're literally doing everything right it sounds like.
Super bazaar dude. I just can't wrap my head around it not connecting. It bugs me 'cause it should work - and its literally working for me.
I've reviewed all my files and I can't think of a single thing outside of the tutorial and the SMB quick start zip that would matter.
You've added GUEST and all that jazz? I'm sorry, you seem to know what you're doing its just I'm an idiot and I got it to work so I feel obligated to try and help.

I just do this and it works every time. Guest access turned on of course. SB.game.ELF. SMB>POPS>game.vcd
I do have GUEST and no password which the tutorial doesn't specify to do actually. Maybe that?
I have my games on PS3 too but thats not really the point.
