If you have made my DIY game system, you'll want to add games. My example one already has games built in,
but yours may not. That's why I'm going to show you how! There are over 9 methods, so I'll show you the basic 3!
Step 1: What You Will Need
1) a DIY game system (if you don't know how to build one, click here.)
2) either: a raspberry Pi OS,
an SD card,
or a premade game chip.
3) a computer (if you're reading this, I assume you have one.)
even if you buy all of this, it should only cost a maximum of $15.00, not counting costs of a DIY game system.
Step 2: Method 1: Raspberry Pi OS
for this method, use a raspberry pi model. Make sure to know where the main solder leading to the processor is, and connect the microcomputer. If you know how to script a raspberry pi, the task should be simple, but I can't go specific as the system will be different with everyone. Anyway, first turn on the system and see if the contact points are aligned correctly. If you're doing it right, the raspberry pi will load games, but the games can be played using the system.
EDIT: sorry guys, still haven't gotten around to buying a Pi myself, when I do (around mid-may) my instructables will be a LOT better!
Step 3: SD Card
This one is, to me, the easiest out of the 3. as most android/emulator users have known, any game can be loaded to an SD card and be used. 'nuff said.
EDIT: for those who don't know, it's mainly just downloadin games to an SD card, and this will only be effective if you have an SD port.
