Follow the instructions at GetLofi.  You're basically providing power to the chip, cutting a trace on the PCB that previously supplied the CPU with a clock signal, and connecting the output of this chip to the CPU's clock input.

Do I really need a 0,1uF capacitor?

Probably not but you should use one.  When you go from +V to GND like this it's being used to help keep the supply voltage stable, which probably helps it keep the output frequency stable.

I got myself some LTC 1799 DIP 6 adapters (http://www.circuitbenders.co.uk/forsale/LTC/LTCDIP.html) to mod some DMG's.

This adapter is slightly different than the LTC 1799 from Getlofi (http://getlofi.com/gameboy-dmg-01-pitch-modification/)

How do I connect this thing? Do I really need a 0,1uF capacitor?
