Hello,

I did not develop for GBA for a long time, but IIRC the multiboot data have
to conform to nintendo's multiboot header, which contains not only important
data about length, starting point, etc... but also graphics of nintendo
logo.
I can't recall the lenght of those data, but I suspect it's several kB
long, I wonder why nobody else pointed it to you yet. (this list is dead?)
As far as I can recall from my hazy memory, I think the MBV cable is using
this propietary format of multiboot data, and there's no way to boot the GBA
with some simpler scheme.

You can still make it trough with booting your GBA from some device with
larger memory (PC?) to upload your own program, which will expect simple
data from basic stamp later, in your own communication protocol, but I think
you wished to avoid that kind of solution.

I think the protocol of multiboot programs for GBA is described on this
basic level very well, if you will try to search a bit, you will surely run
into the information about that nintendo logo, as it had been discussed a
lot due to copyright reasons. The length of header, data format, etc.. is
surely described and floating around, as I have seen them couple of years
ago, when I was new to GBA.

Hi Gick2002, Just out of curiosity, how much memory has you basic stamp got? as if your going to program the gba with something to show output in text on GBA,...

... Well, an 8x8 bitmap font needs 1k per bit of depth, so he'd need 4k for the font. That eliminates the two starter kits (which have 256 bytes of EEPROM for...

Somewhat OT: I would highly recommend other microcontrollers besides parallax's basic stamp. It is over-priced, and under-powered. I've used Atmel's AVR a...

Memory shouldn't be a problem, memory is cheap these days. For example: http://www.sparkfun.com/commerce/product_info.php?products_id=301 4mbit for 3.87 USD...
