SNES OAM tests

This is three programs to test OAM (Object Attribute Memory)

Three programs to test OAM (object attribute memory). This defines the sprites in memory. Presumably written by blargg. There is source code and a readme.

Tests pass on original and mini SNES units.
Asm uses the following:
mov addr, #immediate
	
	lda #immediate
	sta addr
movw addr,#immediate
	lda #immediate
	sta addr+1
set_test code, text
	Saves code and text for printing if test fails.
Jcc addr
	Like Bcc, but can jump anywhere if condition holds.
test_failed
	Reports failure and prints most recent set_test code and text.
check_oam addr, data
	Verifies that OAM matches data, starting at addr.
