 requires some mods to the cpu core in order to start to work...
 Many thanks to Olivier Galibert for the identify effort ;-)
 
+How to initialize this:
+- let it run then soft reset (it wants that ram at 0-0xff is equal to 0xff,
+  nvram maybe?);
+- set a bp 10c5 then pc=10c8, it currently fails the rom checksum for
+  whatever reason (should be 0 and it returns 0x89), note that area
+  0xf00-0xfff isn't tested at all, maybe that belongs to somewhere else?
