88- EEPROM doesn't work. I'm not sure what the program is trying to do.
99  The EEPROM handling might actually be related to the protection which
1010  makes the game hang.
11  See pirates_in1_r() for code which would work around the protection,
11  See prot_r() for code which would work around the protection,
1212  but makes the game periodically hang for a couple of seconds; therefore,
1313  for now I'm just patching out the protection check.

5050The game hanging is an interesting issue, the board owner has 2 copies of this game, one a prototype,
51on the final released version.  The roms on both boards are the same, however the prototype locks up
51one the final released version.  The roms on both boards are the same, however the prototype locks up
5252just as it does in Mame at the moment.  The final board does not.  It would appear the prototype
5353board does not have the protection hardware correctly in place
