Hey i m working in me second portable and planning to make it smaller.
I noticed that on the board i have now there is no u8 chip,
So kinda wondering where i should connect the controller ?

It has 4 smal chips instead of the u8 it is a rev 2 pal board.
I can post pictures if needed.

Thanx for the info will be cutting the board down then.

Yes it is that board only one ram chip.

Another small question can i just cut off the power button ?

Yes you can just cut it off but be careful, i really would recommend de-soldering but care with small long nose pliers also does a clean job.
just be sure to bridge the connections.

on the u8 alternate wiring i cant be sure which pin on the chips is vcc, still multimetering atm

hmm oke but i was more thiking of cutting away the board piece where the switch is sitting on to make it smaller.

i wil be checking the chips and connect a controller to it on wednesday have some free time there =P

well wont be a test my board doesnt seem to work anymore after i cut it =P

is it an official controller?
i have heaps of the boards and the main thing i forget when i cut them is to reconnect ground/vcc and make sure the capacitor is still connected

Controller board is no problem.
My n64 board doesnt want to show anything on the screen pretty sure didnt cut anythhing bad.....
Tryed connecting the power to different places.
What capacitor do you mean ?
And what ground :p
