/*
   NOTES:

   Exact size of internal ROM is unknown, but it appears to occupy at least 0x4000 - 0xffff (word addresses)
   in unSP space and is different for each game.  Data is pulled for jump tables, where the addresses are in
   internal ROM and the code in external

   For correctly offset disassembly use
   unidasm xxx.bin -arch unsp12 -xchbytes -basepc 200000 >palace.txt

   Multiple different units appear to share the same ROM with a jumper to select game.
   It should be verified in each case that the external ROM was not changed

   It is confirmed that in some cases the external ROMs contain both versions for Micro Arcade and Tiny Arcade
   units, with different sound, but in some cases the expected game behavior differs too, so the code revisions
   could be different.  (for example the Micro Arcade Pac-Man doesn't display points when you eat a ghost)
