You have been misinformed.  Memory access in the Amiga between the CPU and
fast RAM is quite fast.  So fast, that adding an L2 cache will not make it
any faster.

Memory access between the Amiga CPU and the "chip" RAM (also known as the
"graphics" RAM) is slow because the CPU has to go through the Amiga's custom
graphics chips to get to the graphics RAM.  Adding an L2 cache there is not

You seem fixated on the idea that adding a Level-2 cache to the Amiga will
fix all of your problems.  It doesn't work that way.  Please accept that
fact and move on.
