I build Hardware for the GameBoy, but after last Christmas I bought a GameBoyAdvance. I think that was your question (GBA) right?
I don't know what's wrong until now. The GBA notice that my Hardware
is for the GB and so the GBA comes up withe the old Z80-processor.
But there is something wrong because the "Nintendo" doesn't appear.
Hey Piotrsus, do you Know something of the GBA-hardware?
The signals of the connector are quite different for the ARM7-processor-mode. And I think if you want to use flash in your application adressed
ba the GBA, the ICs should have accesstime less or equal 110ns.
The old GB and GBColor have a Z80-like processor. The whole system is 8Bit and works with 5V power. The GBA has a 32bit ARM7-processor
and wosks with 3.3V. If you put an old game or something in the GBA,
the GBA notice that because of a small switch (One cartridge has a notch).
If the GBA boots he decides between Z80 or ARM7-processor.
