I know about the switch.. but is it possible to do it with a rom ?
btw.. how does the gba/gbc thing works ? does it start an emulator ? or a special Z80 chip ?
Thankx,
f00l

As far as I remember, then the GBC has a pin more or less on the cart. The GBA simply checks if the pin is conencted or not.
The emulation is done by a Z80 chip.

There's actually a switch on the side of the cart edge connector that GBC carts press and GBA carts don't. If you want to use a GBA flash cart to develop GBC programs, you're going to need a device that presses down the switch and translates between GBA and GBC edge connector protocols. Such a device is called a "GB bridge."

yeah I know about the chip :)
but I was wondering if I could get to the emulation Chip ,
like this :
ldr r1,= "z80 emu chip"
ldr r2,=0xFF
strb [r2,r1]

There is no known way to run 8-bit programs from GBA-protocol ROM or from EWRAM, except through a software emulator loaded into IWRAM.
