Detailed Description

EvmuCpu: Sanyo LC86k CPU Core.

EvmuCpu models the main execution unit on the Potato. It provides an API for executing and fetching info on instructions.

Additionally, virtual methods within EvmuCpu can be overridden to provide custom CPU and opcode implementations.

Todo:

secs per instruction in msec/nsec, not float
pull Rom/BIOS update out of CPU update path
implement/respect halted flags
ensure OV is set when divison by 0 occurs
