-Fixed disassembly for JMP:
--Now it uses the parameter pc, not RegisterPC.
--I was loading both the second and third value from the second's address.
--Casting the calculated addresses to bytes when addresses are 16-bit was a bad idea.
--Removed a closing parenthesis I accidentally stuck in the formatting.
It seems that I've gotten far enough to use the Executive ROM as a test case! Now to go instruction by instruction and see if they work as planned and hope this will all eventually make something.
-Fixed JMP disassembly; I need to return on an invalid opcode because I was breaking out of the inner switch statement, not both that and the outer one.
-Made all instructions in the executor, even implemented ones, throw exceptions. I will get rid of the exceptions as I test the instructions.
-Added instructions up to and including 0x57 to disassembly and executor.
