Ivan = 1er version. I have no idea if "The Conquerer" can be dumped.

And there are 2 versions of "The Terrible", I believe this is the first version. This one actually had the Mirage MCU. The internal ROM is disabled, program is on external EPROM. Sean dumped this MCU anyway, and together with some old Mirage PCB photos by Berger I was able to write the emulation of Mirage too.
