Mega Everdrive Pro Firmware v4.12

Krikzz has just released a new firmware for the Mega Everdrive Pro, which allows support for the upcoming game Demons of Asteborg:  A new Genesis game that has an official ROM available to purchase.  While the game isn’t released yet, it looks awesome and I’m happy to see support added to the MEDPro!

Demons of Asteborg:

Another addition to the firmware, is the ability to enable the Sega CD core for Genesis games that can use the SCD hardware, even if there isn’t a disk image associated with that game; This is done simply by changing one letter in the ROM header, then coding the ROM to look for the extra hardware.  Here’s the full list of changes included in this firmware update:

  • Data initialization for blank 24C08 eeprom
  • Included support for Demons Of Asteborg
  • CD hardware enabling if the “C” letter is found in the device support list (ROM address 0x000190)
  • In-game menu remember the last selected item
