zeromus 3c6549a7bb snesgfx-decode mode7 graphics 2012-09-21 17:21:21 +00:00
zeromus 72d4fefbe0 snesgfxdebug-fix 8bpp tile decoding and 16x16 tilemap rendering 2012-09-21 08:10:14 +00:00
zeromus 708b98b4b8 enum.HasFlag -- too good to be true? yes. 40x slower than doing an old fashioned bitmask check. 2012-09-21 07:10:54 +00:00
zeromus 70392be4e4 snes-all memory domains were showing WRAM instead of the right thing; fixed 2012-09-21 06:03:27 +00:00
zeromus 526078f578 snes-work on graphics debugger. some relayout, plus palette viewer 2012-09-21 05:56:47 +00:00
goyuken c026b2dc81 slightly optimize previous commit by avoiding 32k unmanaged=>managed transition calls per second when skipping audio 2012-09-20 20:36:44 +00:00
goyuken 176ecd8650 support for !rendersound in LibsnesCore
worth about 5-10% on my machine in secret of mana opening
2012-09-20 20:25:40 +00:00
goyuken 51fc8e695c add 'bool rendersound' to IEmualtor.FrameAdvance()
if false, the emulator is free to gain whatever speedup it can by not doing audio processing (shouldn't change anything sync related, though)
the core should still always call SoundProvider.GetSamples() after each FrameAdvance(), else DRAGONS
at the moment, only test-implemented in gambattehawk

goyuken 1301344d71 neshawk: fix: when paused, toggling "clip left and right 8" in nes graphics config caused garbage to show on screen. 2012-09-20 00:53:21 +00:00

zeromus 4018452f21 add CoreInputComm.CpuTraceEnable and CoreInputComm.CpuTraceStream, and use it in NES; set those appropriately from a gui component and you can effect user-controlled cpu tracing, if its been setup in the core he's interested in. CoreInputComm doesnt reconstruct between emulator instances, so this may not be the best way of hooking it up, but its serviceable. 2012-09-16 19:38:08 +00:00

goyuken 27b5d29f0c Gambatte: soft resets (all 3 lines of code!)

goyuken bf5625655d rename gambatte memory domains per todo list 2012-09-13 21:19:26 +00:00
goyuken 12d06a2c94 add system bus memory domain to gambatte
in order to guarantee correct resolution of mappings and mmio every time, all calls go straight to the core and are not cached
this makes this domain slower in performance than the other ones.  it can also be more difficult to use in some cases because you have to resolve mappings that you may not care about.
there is also the possibility of side-effects on reads, although i do not believe that this actually happens in any situations.  still, use at your own risk.

goyuken 578e247524 add lag counter to LibsnesCore
per ilari, this should work correctly on certain games that poll the input in a particular way.  however, it is completely non-functional on many other games.  core digging is required for anything better.

brandman211 fd1560177e -Implemented Colored Squares mode. It looks sensible in one of the improperly loaded ROMs that triggers it.
-Masked the Color Stack registers. This prevents the previously mentioned ROM from throwing an ArgumentException in ColorToRGBA.
2012-09-06 08:02:49 +00:00
brandman211 a6f11a7ade -The STIC now displays the encoded background color when one is provided.
--The only time I've seen this was in a game that used FGBG mode, and it looked messed up.
-Implemented the parsing of the background for Color Stack mode.
--Because the STIC Registers aren't populated, this doesn't do anything. I'm not sure when this is supposed to occur.
-Determined when Colored Squares mode is active. I'll try to implement this mode shortly.

brandman211 06022c9076 -Added Read/WriteMemory to the STIC so that it can access the RAM it needs to draw the screen.
--Did the same for the PSG because why not.
-Discovered that the Commando HLT happens after the CPU goes idle, so there's no point in further investigating the issue until I emulate that.
-Parsed the BACKTAB cards for the STIC's Draw().
-Attempted to draw the screen using the aforementioned cards.
--I'm only trying to apply color to the foreground.
---Instead of converting the FG color to RGBA, I'm making it all white for now.
--There's clearly some sanity to what's being drawn, so I think each 8x8 card is being drawn in the right place.
--I think the next step is trying to make each individual card draw properly.
--I believe the algorithm for populating the FrameBuffer is VERY inefficient in the way it accesses memory. Will need some suggestions as to how I can rewrite this.

goyuken a85dadcf7d did a bunch of listening tests with libsnes and metaspu. switched to vecna metaspu
it seems to be the most stable when the system is fast enough to maintain approximately 100% speed.

also fixed up metaspu in dumping and switched it to vecna.  i can now have clean audio while running libsnes with lua script and ffmpeg dumping.

goyuken b0e3a332d8 abstract resampling functionality into IStereoResampler for testing purposes
add two example resamplers that implement this: LinearResampler and CubicResampler.  both are very basic and sound like shit compared to libresample4j
ultimately, a single good resampler with a better license than libresample4j should be selected and used
2012-09-05 21:21:35 +00:00
goyuken 0430ec91c8 add resampler based on libresample4j (LGPL)
hook that up to libsnes, so libsnes audio now goes through libresample4j and then metaspu
it sounds ok

brandman211 1a760096bc -Laid out the groundwork for the video provider.
--VirtualHeight / Width will be useful due to how the scanlines are doubled on TVs, but for now, I will just be drawing to scale.
-Enabled XOR@, SAR, and COMR. Advanced Dungeons & Dragons provided more test cases.
-Noticed that Commando, as well as some other games, triggers a HLT. This should be looked into later.

brandman211 44e03b1923 -Changed the amount of pending cycles to add when the STIC sets SR1.
--This number is fairly arbitrary, and I don't know why it works, but for now, it does.
--The values of INTRM don't match up exactly, but I think this is mostly a logging issue, though I still need to look into this.
-Fixed the Overflow Flag calculation.
--My original formula didn't compare the signs of the operands.
--It always needs to use the original operands, not the 2s complement one.
--As such, a result parameter has been added.
-Fixed the detection of a double swap, shift, and rotate in the related instructions. Ironically, I shifted one too many bits in my detection.
-Masked the result of left shifts and rotates to 0xFFFF so that the flags are calculated properly.
-Made RSWD (un)set the right flags.
-Enabled GSWD, MVI, SARC, CMP@, ADD, SUB@, INCR, RRC, SLR, SLL, RLC, ADDR, SUBR, SLLC, CMPR, and RSWD.
-COMR, NEGR, ADCR, SAR, ANDR, SUB, AND, XOR, and XOR@ remain disabled as I have yet to hit any test cases for them.

At this point, IntelliHawk is executing instructions indefinitely with what seems to be perfect results! I think I'm ready to hook up the screen.

-Added and Interrupted flag to make it so that interrupts only trigger once per falling edge.
-For now, interrupts take 28 cycles.
-Made it so that the STIC tracks Pending / Total Executed Cycles just like the CPU.
-Forwarded the cycles executed in the CPU to the STIC's Execute.
-SR1 is now inverted when there are no pending cycles.
--If SR1 is high, 14394 cycles are added to the pending cycles.
--If SR1 is low, 3791 cycles are added to the pending cycles.

brandman211 26b1d06b7a -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
brandman211 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.

--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.

brandman211 0a3a392285 -Attempted to parse out memory attributes.
--In my test case, only a few segments were set to readable and nothing else was set. 0x1000, which is where the PC is initialized to, certainly isn't in a writable page.
--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.
-Hooked Read/WriteCart into Read/WriteMemory.
-Implemented memory attributes into Read/WriteCart.
--TODO: Bank-switching.

TODO: Fine address table and memory attribute / fine address checksums.

brandman211 4f9539b73c -Made Executive ROM and Graphics ROM read-only. I still haven't made the memory map accessibility limited by the VBlank Period, but I'm assuming that should come way later.
-Initialized the memory devices with a tentative size that ignores the unofficial ranges.
-Masked addresses to match those sizes (That's my understanding of what the memory map needs to do based on other examples).
-Added the ICart interface.
-Started the Intellicart parser; got far enough to know that the files I'm working with are not Intellicarts. ^_^
