Preflashed region free bios for your dreamcast.
Options available are:
MX29F1610 (5v) for VA0
MX29LV160 (3.3v) for VA1 and VA2.1
Installation instructions can be found here: http://www.mmmonkey.co.uk/sega-dreamcast-region-free-bios/
We are now supplying the MX29F1610A not the MX29F1610 for VA0 consoles. There is no functional difference (A is a newer revision of the same chip). However, the currently released version of dreamshell doesnt support flashing this chip. Please download this version to reprogram the chip in system: Dreamshell MX29F1610A
