R4-R7 now auto-increment for all of the indirect opcodes. My documentation is inconsistent on whether R6 increments or decrements on right, but in any case, my output now matches my source until the DECR, which hasn't been implemented yet.

-Reverted disassembly printout as it'll now match up with my comparison.

-Fixed the branching disassembly; the direction just negates the offset and the second parameter only belongs to BEXT. All of my sources contradict each other, but this seems sensible.
2012-07-24 05:29:24 +00:00

-Put the disassembly in parenthesis and put the opcode to the left of it in the logs. This is uglier, but it's initially easier for comparison this way.
...
-RegisterSP now increments in MVO@ instead of decrements. I'm not sure how this allows the stack to function properly, but it seems to work.

-Refactored of the executor / disassembler / Intellicart to use more descriptive variable names and types to clear up a lot of confusion.
...
-Added implementation for NOP (6 cycles of nothing).
-Made SWAP actually store the result (Still disabled).
-Added breaks to the swap / shift / rotate cases (Yikes).
Instruction disassembly:
JSRD R5, $1026
MVI@ R7, R6
JSR R5, $1A83
MVO@ R5, R6
MVO@ R0, R6
MVO@ R1, R6
MVI@ R7, R4
MVI@ R7, R0

MVO@ R5, R6
XORR R5, R5 <- Needs implementation.
2012-07-21 05:25:52 +00:00

...
-Disabled Intellicart hook for ReadMemory, which seemed to be interfering.
-Implemented MVO@.
-Several instructions are now executed in succession until it hits the unimplemented "XORR R5, R5".
I should probably refactor Disassemble and Execute to label registers as source / destination to avoid further confusion at some point. My disassembly might have the source / destination registers flipped as well.
2012-07-20 07:22:41 +00:00
b2323458ba
Implemented / tested MVI@ and AND@.
...
-They both seem to work, but the operands for AND@ are both 0, so this seems fishy.
-I don't know for sure if AND@ executes cycles in the same way that MVI@ as the documentation isn't clear on this, but I assumed it did.
According to my disassembler, the first 5 instructions run on the Executive ROM are:
JSRD R5, $1026
MVI@ R7, R6
ADD@ R6, R1
JSR R5, $1A83
HLT
Considering that I hit a HLT, I figure something is going terribly wrong. Perhaps it has to do with my lack of an interrupt system?

-Fixed disassembly for JMP:
--Now it uses the parameter pc, not RegisterPC.
--I was loading both the second and third value from the second's address.
--Casting the calculated addresses to bytes when addresses are 16-bit was a bad idea.
--Removed a closing parenthesis I accidentally stuck in the formatting.
It seems that I've gotten far enough to use the Executive ROM as a test case! Now to go instruction by instruction and see if they work as planned and hope this will all eventually make something.

--Afterwards, the data is reconciled, right now by chucking out the core value if the cart responded.

--Each case now breaks out of the switch statement in case we want to do more complex things at the end of the function later on.

-Implemented the final CRC check.
I didn't get around to implementing bank-switched ranges, but I don't think it's worth worrying about that right now considering that the Intellicart is not marked as readable at the initial PC, so something is either wrong or I need to implement more things before this will work. I think I'll put Intellicarts on hold and try to get a .int / .bin to run in the meantime.

Add VirtualWidth to IVideoProvider and the (numerous) implementations. This is just phase 1, client needs to be updated to utilize this information, and some cores (especially PCE) should be updated in a more involved way to provide better TV emulation.

nes-mmc3/namcot108 differences have become more clear in the past few months. refactor those mappers (split them apart, theyre not as similar as once thought) to reflect new understandings. no functional improvement from this other than maybe some new bugs, but it will help on some other mappers later

-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

-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.
