brandman211 8d254113c2 Finished the opcode decoder. Over a thousand lines in one day...now just to make them do stuff! 2012-07-08 03:53:12 +00:00
brandman211 1c480c98b4 -Created functions for calculating the flags. 
-Implemented ADCR.
-Decoded all opcodes up to 0x23F.

TODO: Try vecna's idea of testing the instructions by running a game and implementing instructions as I need them...but first I'll need to implement loading of an Intellivision game.
