  • smf fixed a couple of issues with hard disks without checksums
  • Brian Troha corrected DIP switches for Karate Blazers, Turbo Force, Raiden 2
  • Ville Linde updated the SPI / 386 drivers:
    • Added the missing keys to E-Jan
    • Added layer enable register
    • Wrote a new i386 disassembler. Dasm386 wasn't always showing stuff correctly, and now the i386 core can be compiled without i86.

    • Added 93C46 eeprom to RF2 single and RF2 2K. It's not hooked up though.
    • Improved i386/z80 interleaving. This should help with the small pauses.
