change CoreOutputComm to use exact integers to specify VsyncRate. Helps for AV dumping with formats that require exact integer rates (AVI), and for emulators that aren't exactly 50hz/60hz (none yet).

-Made the memory map use ushort arrays because the Intellivision is 16-bit.

-Intellivision.cs' constructor initializes the PC to 0x1000.
...
-Set up the "official" memory map - see http://wiki.intellivision.us/index.php?title=Memory_Map
--Things I didn't do:
---Accessibility.
---Additional Occupied Memory Ranges.
---Addresses Available to Cartridges
---Initialize any of the byte arrays.
--Not sure which of these I need to do, but clearly the byte arrays have to be initialized somewhere to something and there's a lot of gaps in this memory map.

-As I'm not going to know what I'm doing if I keep hacking away at zeromus' old core blindly, I'm writing a new one.
...
--It's going to be based heavily based on Imran Nazar's "GameBoy Emulation in Javascript" series. I figure it's better that I learn by emulation (Har har) instead of spending more time reading references than programming.
--Finished the memory management (Part 2).
--adelikat:
---Do I implement the required functions for IEmulator and IVideoProvider now, do it later, or is this something you or zeromus would do (Like for the API)?
---At what point should we have the emulator actually use this core instead of zeromus'? As terrible as he says his is, this one doesn't do anything yet. Still, I need some mechanism of testing it.

-Made it so that the log file only opens when you're actually logging. As a result, now can now at least switch games when you're not logging without getting errors.
2012-05-24 17:27:45 +00:00
b29c9835ff
-Separated the logging from the save state function.
...
-Made it so that the log only opens when logging is true and that the file closes upon destruction.
--Still, BizHawk says that it can't open the file again when I load a game again. This is because the emulator class gets recreated without deleting the original one every time you load a game.
---adelikat convinced me not to care about this.
-Fixed the initial state of the GB CPU:
--It was setting AF to 0x01, not A. This is effectively setting F to 0x01, which gets overwritten later anyway.
--Two BIOS flags were used in different places; merging them gets the PC to start in the right place.
-By fixing the initial state, most of the log now matches up.
--The only differences are the VBA has some repeated records (Where all of the registers, including PC, are the same as the previous record) whereas BizHawk doesn't.
--This very well might be an issue with how I'm logging it
--Alternatively, it could be some kind of lagging mechanism.
--I'm not sure which version is even correct...VBA is far from accruate.
--All in all, considering that the vast majority of the diff comes out as the same, I think I fixed the biggest CPU related bug. Will investigate more later.

Add sound output to sound card while dumping is occurring. Uses a proxy ISoundProvider (DualSound.cs) to guarantee emulation sound core and dumping routine are unaffected, while sending "best effort" sound to system output. Doesn't sound great, but simple and functional.

-Added a very basic fix to the graphics scaling issue per adelikat's advice.
...
--Gets worse as the scale increases.
--For x3, the box doesn't increase size, but the box still changes position. I think there might be a difference between the TargetZoomFactor and the actual screen size, so perhaps we should tie this to something else.
-Working on very small optimizations to the NES PPU with CorruptedSyntax...this is more fun, so we'll do this first.
--Eliminated an entire loop.
--Branched to two loops instead of branching for every iteration in one loop.
--Got rid of some redundant instructions using temporary variables.
--This may be completely premature, but I seem to have gained a few FPS from doing this. For me, I get 38-39 FPS where I'd previously get 33-34.
