NesDS not working on Nintendo Macro with Twilight menu

[hpmulder]

NesDS has the ScreenSwap option, but this is ignored when launching a rom via arguments (like Twilight menu does). This makes it impossible to use NesDS on a Nintendo Macro, which has no upper screen.

I checked the code, the fix might be as simple as doing this in arm9main.c:

if(!bootext()) {
	//chdir("/");
	do_rommenu(); //show a menu selecting rom files.
}
else
	hideconsole(); // make sure all ini-file settings are applied.

But I am unable to check this, as I cannot get the toolchain to run.
