I've finally saved up the money for a GBA again. ;D So once I get that (should be today), I'll start anew.

But does anyone know how to get started? I still have no idea on how to actually start writing code that would even begin to run on a GBA, much less communicate between a GBA and a CE.
You can't link a GBA to a CE, because TI removed the link port.

Doesn't the mini-USB of the CE have a proper controller now? It might work.

Yes, but there's no USB on a GBA. Unless you can toggle and read the data pins on the CE directly, it won't work.

For the cables. For example, there are serial to USB converters and vice-versa (eg if someone has no serial port on his PC). So I was wondering if there was one for GBA <> USB.

Actually, if you got a USB to Serial adaptor that might work, as (I think?) the latest CE OS has USB serial stuff.

So I'd have to get a converter, and connect it that way. Hmph.

I think the best thing to do it make a converter yourself, because I doubt that there will be GBA <> USB adapters readily available. I bet that the best thing to do would be having an usb interface in e.g. an arduino and interface with the gba over serial. So an active converter (more like an interface in that case)

How would I get started building a converter? After all, it's 6-pin (GBA) to 5(or4)-pin(CE) (if I remember correctly)

The way I'd go about that is have an active interface between the two sides. So CE (5 pin) -> microcontroller  over GPIO-> GBA

caleb1997

So it'd be like this:

CE(5 pin)-> Raspberry Pi->GBA. Am I right?

Or any compatible microcontroller, yes.
