Technica information on Gameboy Advance PCB and catridge connectors?

Hi, there:

I am studying ARM assembly programming and FPGA. I can program some simple
programs with the LCD and buttons.

I need some technical information on how to interface with the FPGA through
the catridge connector.

Thanks for your leads.

Elektor magazine published a design a while ago for a cartridge that converted
a standard Gameboy into a scope. Since the Gameboy Advance is compatible with
Gameboy cartridges, there may be some similarity between the cartridge pinouts?
Sorry, I'm not sure what issue it was in, but I think they have an index on the
website, so try Google?

I found it, it's on sale but it doesn't have information on the actual
design.

Thanks for the lead.

Your Googling skills obviously aren't up to much, here is the complete
article:

If only it could have managed even 5MHz we might have been able to convince
our boss that we all needed one in our toolkits.

Hiya,

I was looking at this sort of thing once as well, I found
http://www.devrs.com/gba/
to be quite useful.
Have you heard of the XPort
http://www.charmedlabs.com/xport.htm

I hope these are of some assistance.

Yea. I am reading Xport.

Thank you.

Gameboy Classic cartridges uses 5 volt signaling where as Gameboy 
Advance cartridges use 3.3 volts. This is used by the Advance to detect 
the cartridge type and hence select which pin-out to use with the 
cartridge as they differ. The Classic uses 16 bit address bus with an 8 
bit data bus while the Advance multiplexes a 24 bit address bus and 16 
data bus on the same pins. I don't think that you can't execute ARM 
instructions from a Classic cartridge and hence are restricted to the 
Classic's Z80ish environment. You might find the following PDF useful. 
It contains details of the Advance's cartridge interface.
