That kind of depends on what you mean by changing the arm9 entry address. What's this for?

acekard 2i autoboot, if the ARM9 adress is 0x02000450 it boots, if the ARM9 adress is 0x02000000 it doesn't boot...

Add this to the LDFLAGS in your arm9 makefile.
Code: Select all
-Wl,--section-start,.init=0x02000450,--nmagic
.init is the first section in the binary, used to make sure the crt0 goes at the start regardless of link order, --nmagic prevents the linker from aligning the output sections to a page boundary. 0x02000450 is obviously the requested start address and can be anywhere in the 4meg region.
