RPI GPIO and Pinout questions?

[brakanje]

Hi I’m trying to wire up an Atari style controller port I got from an old NES-on-a-chip game i had that no longer worked and want to wire it up to the RPI so I can use my Atari2600 CX40 in Atari games.

These are the pinouts I have found. I was wondering what I2C, UART, SPI are and if it is safe to use them?

Failing them I figured I would Attack the pins like
Atari RPIB+
1 29
2 31
3 33
4 35
6 37
7 2
8 39

However someone at atariage was telling me that i need pickup resistors and was saying something about using 3.3 and attaching it to each pin. All in all I’m rather confused.

So it’s been about 12 hours. I’m thinking I posted this in the wrong section and that it may have been better to put it in the projects directory? If so could some mod maybe move this there?
