Hey, I have a question.

Where do you get the Link Cable in PMD 1?

I need it to evolve Machoke, my starter.

Sun Cave 10 F, And Sun Cave 15F. If you've already gotten the HMs that are there(and have a key, of course) there will be a Link Cable taking their place.

Thanks a lot.
But how do I get to Sun Cave?

 

[Sarcastic Prince]

Er, I mean Solar Cave. x_X; Sorry about that.

Doesn't matter.
But how do you unlock Solar Cave anyways?

Apparently it should've already been unlocked after you beat the game. o.o

Yeah you're right :)
Maybe SP should get Dive first and then Solar Cave will be unlocked ;)
