@ -11,6 +11,11 @@ Temporary split from raiden2.c, it'll be re-merged at some point.
Raiden 2 / DX checks if there's the string "RAIDEN" at start-up inside the eeprom, otherwise it dies.
Then it puts settings at 0x9e08 and 0x9e0a (bp 91acb)
the 333 ROM is a 0x10000 byte table (bytes values?)
followed by a 0x400 bytes (word values)?
the remaining space is 0xff
