Okay. I tried to do a experiment: Make the hidden japanese text appear on Plane B, instead of Plane A.

So, as I understand about manipulating registers, I did this:

From:

		move.w	#$8230,(a6)

		move.w	#$8407,(a6)

To:

		move.w	#$8207,(a6)

		move.w	#$8430,(a6)

After that, I just get a blank screen. Also, If I open a savestate of that screen with GSavestate, it tells that Scroll A and Scroll B points to $0000.

What is the problem here?

Not sure that's the problem, but one important thing to keep in mind is that plane A and plane B aren't using the same addressing system. If A is set to "30", it points at C000, but if B is set to "30", it points at 60000. Originally, in the code you're showing code, it was C000 for A and E000 for B.

for A, divide the address by $400, and for B by $2000.
