[ZR23NENE] A BG test program I cooked up. This should prove useful for a future project.
A/B: BG Zoom In/Out
X: Quit
Y: Reset
+: Pan BG
L/R: Rotate BG counter/clockwise
Touch: BGCOORD Test
CHRLOAD/CHRSAVE commands to copy and load text characters in the console layer with an array, like BGLOAD/BGSAVE. Sorry for English, I don't speak Japanese (I'm a US fan eagerly awaiting release).
