-Simplified the CPU / STIC connection.

-Made FrameAdvance handle the pending cycle loop. During each iteration, it runs one instruction and ticks the STIC accordingly.
2012-08-14 03:58:11 +00:00
9100232547
-Made connections between the signal pins on the CP1610 and the STIC.
...
--Not sure why the STIC has any connection to the SST, but the docs on the SST are virtually non-existent from what I could find.
--I took advantage of Func and Action instead of passing bool references to both devices. I think this makes sense.
-Added reset functions for both devices.
My comparison log for INTRM is still weird because it says it is true initially (Expected) and remains as such after the first instruction (A bit odd). I think this happens because the STIC is supposed to "tick" and shift SR1 to false immediately, but the STIC tick happens after the CPU tick, and the CPU tick is where the logging happens. I need to find a better place to put this logging, and I need to implement the STIC ticking for IntelliHawk. I'm not positive how to approach the latter issue as I assume a tick means one instruction execution, and my executions happen in a loop on the CPU, which has no reference to the STIC, so I'm not sure where this fits into the equation.
2012-08-13 08:10:15 +00:00

Implemented what to do on an interrupt. This seems to be logical as it tries to execute a GSWD instruction, but it takes the interrupt too early because I haven't figured out when to turn INTRM on / off.

-Separated the STIC and PSG memory map logic into new objects.
...
-Foreground / Background | Color Stack Mode
--Actually made a boolean for it (FGBG).
--Reading from a write-only STIC alias of $21 does change the STIC into Color Stack mode, but it doesn't actually read.
--Color stack mode is enabled when $21 or its alias is read and it is disabled (FGBG) when written its written, both having to occur during VBlank Period 1.
---This is what I gathered from the wiki, but I'm confused as to why it says that "The STIC stays in this mode until the program accesses location $21 again." I'm assuming this doesn't mean the mode changes on every access because then I don't understand why a read would change to a different mode than a write.
--FGBG is disabled by default. I don't think it matters.

-When neither the cartridge nor hardware responds to a read, it now returns 0xFFFF instead of throwing an exception.
...
-I will now assume that 0x7000 is not mapped for the sake of continuing on. I will need to implement a mapper system shortly though.
--Did the same thing for 0x4800.
-AND@, MOVR, CMP enabled.
-Made the logging separator generate before an instruction instead of after the register states. This is quite petty, but I don't like the separator at the end of the file.
I hit an infinite loop, and I'm very very certain it's happening because I don't have an interrupt system yet. Time to stop avoiding that!

TODO: Parse the vanilla Intellivision ROM, which will hopefully include the read / writability of the data segments. adelikat seems to think that I just need to send the bytes to $5000, but I'm not convinced.

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.

-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.

-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

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?

-Loaded EROM / GROM.
...
-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.

-Refactored ReadMemory so that both the core and cart addresses are read.

--Afterwards, the data is reconciled, right now by chucking out the core value if the cart responded.
-WriteMemory now writes to both the core and the cart unconditionally.
--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.
-All default paths in both functions now throw an exception.

-Parsed / implemented fine addresses for the Intellicart.

-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.

--Although I've read that these memory attributes affect the Intellivision and not the Intellicart, I'm pretty sure this has to be implemented in the Intellicart so that my Read/WriteCart functions can choose to respond / not respond depending on these attributes. I very well could be wrong.

-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.

...
--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.
