TODO:
-unemulated screen flipping;
-jngolady: RNG in this isn't working properly...looking at the code,when the mcu isn't on
 irq routine there's a poll to the [8] ram address,unsurprisingly it's the RNG seed.
 The problem is that when the rti opcode occurs the program flow doesn't return to feed the
 RNG but executes another irq,probably there are too many irq pollings and the mcu goes out
 of cycles...for now I'm kludging it,my guess is that it can be either a cpu bug,a comms bug
 or 8 is really connected to a RNG seed and the starting code is just for initializing it.
