saxxonpike	6fdc7284bd	Commodore64: Split Sid classes into three files, up from one. Fixed border timing in TimingBuilder. Renamed Sync class to SaveState.	2013-08-26 19:22:04 +00:00
saxxonpike	4ef73eb676	Fix some compiler warnings. Border is still odd, needs the other half of the border unit logic. Also, a marginal performance boost from sealing classes.	2013-08-24 17:30:46 +00:00
saxxonpike	2e7935938a	Commodore64: Split up and moved source files. No user-observable changes in execution.	2013-08-20 07:27:59 +00:00
saxxonpike	b5fcb81727	Commodore64: Save states implemented.	2013-08-19 03:42:40 +00:00
saxxonpike	d6056bb402	Commodore64: Fix VIC addressing for Ultimax format cartridges. PLA implementation should be 100% complete now	2013-08-18 04:27:08 +00:00
saxxonpike	e9bacfd683	Commodore64: More preparation for savestates, condensed the PLA (this is as fast as it can get)	2013-08-18 03:58:39 +00:00
saxxonpike	0b6bce0198	Commodore64: Fixed NMI not triggering on the CPU. Significant performance boost from PLA optimization and motherboard glue shortcuts.	2013-08-17 23:15:31 +00:00
saxxonpike	af9bbd9ae4	Commodore64: Tweak Joystick 2 input.	2013-08-14 13:53:48 +00:00
saxxonpike	5c37b64eec	Commodore64: Removed a lot of unnecessary function chains and converted unsigned types to int.	2013-08-14 05:05:17 +00:00
saxxonpike	9c8124bfd1	Commodore64: Added short circuits in PLA chip select for improved performance	2013-08-13 19:00:11 +00:00
saxxonpike	a061e898a6	Commodore64: don't use color-ram selector pin on PLA, marginal performance gain	2013-08-13 01:55:39 +00:00
saxxonpike	842ead8c7e	Commodore64: Fully implement the interaction between Cpu, Vic and PLA on BA/AEC lines.	2013-08-12 05:04:50 +00:00
saxxonpike	c02f79e99c	Commodore64: Rewrote PLA to fix chip select problems.	2013-08-11 02:46:27 +00:00
saxxonpike	75f279a30b	Commodore64: Writing to expansion memory space while banked in does not write through to underlying RAM.	2013-08-09 05:33:40 +00:00
adelikat	cff1ff2940	Removing unused directives from a bunch of files because I was playing around with resharper, but that got boring so not every file	2013-04-14 20:39:19 +00:00
saxxonpike	c64951fce8	commodore64: implement motherboard configuration, add sprite-sprite and sprite-data collision interrupts to VIC	2012-12-05 21:07:51 +00:00
saxxonpike	e60f308af0	commodore64: savestate support for all chips + cartridge	2012-12-03 08:38:12 +00:00
saxxonpike	ae8566a0df	commodore64: made some input changes (more fixes to come later), removed some duplication in pin information between PLA, CPU and cartridge port	2012-11-30 21:12:23 +00:00
saxxonpike	c1f9a131d5	commodore64: add mapper 000B (some educational titles) and mapper 0011 (a couple obscure games), increase PLA memory map efficiency	2012-11-29 20:15:02 +00:00
saxxonpike	e4c760be83	commodore64: fixed Ultimax E000 mapping, updated mapper 0000, added EzFlash mapper 0020 (no official games use this but a lot of disk-to-cart and homebrew do)	2012-11-29 17:58:35 +00:00
saxxonpike	d05bd47ed0	commodore64: add cartridge mapper 0005 (Ocean), should cover a few high profile games	2012-11-29 06:29:42 +00:00
saxxonpike	1e6fdc2659	commodore64: VIC reads from proper bank, increased performance	2012-11-29 02:46:35 +00:00
saxxonpike	e490d1be04	commodore64: input added back, this method is closer to the circuitry itself	2012-11-28 17:26:40 +00:00
saxxonpike	8e55810161	commodore64: more video function implemented in the new system, 12 pixel delay also applied to border	2012-11-28 06:21:52 +00:00
saxxonpike	49a847d8bc	commodore64: VIC timing fix, implemented new cartridge I/O which handles writes into ROM addresses (apparently some carts use this)	2012-11-28 03:30:59 +00:00
saxxonpike	95d228f413	commodore64: new core with focus on low-level comm between chips and activity on both phases of the clock	2012-11-27 05:11:40 +00:00
