That kind of stuff doesn't work on dial-up though, becuase you get: 2,300 hours remaining, time elapsed 2,200 hours :lol:

Almost all ARM processors are compatible... That's the reason the DS can run GBA but not original Gameboy (the original GB ran on a Zilog80 processor at 3mhz). The DS itself is Powered by an ARM9...

Actually: no.

The DS has two Arm CPUs one Arm9 @67mhz and one Arm7@33 mhz.

In DS games both cpus are used. In gba games the Arm7 gets locked at the 17mhz clockspeed of the original GBA and is running the games as it was the GBA itself.

However I don't know how compatible the different arm series are, the Arm7 is much slower than the Arm9 missing some nice instructions they added to the Arm9 series. But if the Arm9 was compatible with the Arm7 then I don't see the need for Nintendo to include the exact same cpu in the DS, that the GBA allready has ;)
Well for one, the ARM7 is used because the DS already has it... Why use the arm9 which uses up much more power for GBA games if you could use the ARM7? All you would have to do with emulation is convert the roms into ARM9 (which is possible, that's how GPAdvance works...), and then run them in an emulator...
