/* Detailed 0xe50[01]xxxx search
On the SH-4A this region contains the OLRAM. On the SH4AL-DSP it is supposed
to contain nothing, but on the calculator the XRAM and YRAM (normally in P1)
use part of the SH-4A OLRAM region. How exactly they wrap around is
uncertain, so this analysis finds independent pages accurately. */
