Peter Evans	89ddd20658	Add read_byte function to return the next byte in memory	2017-12-05 20:40:35 -06:00
Peter Evans	50a84b4099	Remove cycles field from mos6502 struct ... It was both unused and not necessary, as we can simply compute the number of cycles in the execute function.	2017-12-05 20:23:17 -06:00
Peter Evans	5ada987c83	Add the execute function for the 6502 ... This executes a single opcode. Note this also makes a change to the get_address_resolver function such that accepts an opcode, not the address mode itself.	2017-12-05 19:01:43 -06:00
Peter Evans	eaaf63a069	Zero out last_addr and cycles ... This fixes a super-annoying bug in the unit-test suite where we would fail randomly because sometimes last_addr would have garbage in it.	2017-12-05 18:41:34 -06:00
Peter Evans	8454d1a6c9	Add instruction handler function, handler table	2017-12-05 18:38:36 -06:00
Peter Evans	54473be302	Add functions for instructions, cycles, and address modes. ... This also adds a new table for cycles, and adds unit test functions for the work as well.	2017-12-04 23:30:18 -06:00
Peter Evans	87de0a877a	Add all our tests, plus other fixes	2017-12-03 20:19:17 -06:00
