goyuken 99f6bbb8e4 a few more comments on the new sound stuff 2012-10-11 01:14:14 +00:00
goyuken b40897bb77 sound api changes. added a new ISyncSoundProvider, which works similarly to ISoundProvider except the source (not the sink) determines the number of samples to process. Added facilities to metaspu, dcfilter, speexresampler to work with ISyncSoundProvider. Add ISyncSoundProvider to IEmulator. All IEmulators must provide sync sound, but they need not provide async sound. When async is needed and an IEmulator doesn't provide it, the frontend will wrap it in a vecna metaspu. SNES, GB changed to provide sync sound only. All other emulator cores mostly unchanged; they just provide stub fakesync alongside async, for now. For the moment, the only use of the sync sound is for realtime audio throttling, where it works and sounds quite nice. In the future, sync sound will be supported for AV dumping as well. 2012-10-11 00:44:59 +00:00

goyuken c24abbcbad libsnescore: make deterministic mode savestates all the same size (previously, frame 0 savestates were slightly smaller)
rewind: throw a slightly more intelligible exception message when savestates differ in size
2012-10-08 18:18:43 +00:00
goyuken c167c043e1 rework libsnescore's deterministic savestate mode. like before, savestates are created every single frame. unlike before, now they are created on the frame before they "happen". this is all presented invisibly to the user. don't try to load old savestates in deterministic mode. don't try to mix deterministic and non-deterministic savestates. playing back old movies (provided they don't start from a savestate) should cause no problems, but may or may not sync. 2012-10-08 14:37:42 +00:00

goyuken 98d9f13600 change IEmulator.DeterministicEmulation to get-only; the old interface implies that a core should be able to take a change to the property at any time, which isn't feasable. most existing cores changed to return true all the time.

goyuken d4f5ed2f50 Movie playback and recording will now set IEmulator.DeterministicEmulation = true; only snes core actually does anything with this. It hasn't been explained before in a log; so I'll do it now: When in deterministic mode, the snes core internally does exactly one savestate each and every frame. Then, if the frontend calls savestate at all, it always gets the same internal cached savestate. If the frontend doesn't call savestate, then the internal savestate is simply discarded. This way, the exact same number of RunToSave() calls occur every time. 2012-10-01 14:39:52 +00:00
zeromus 2b1e04997c snes-try more accuracy in the wallclock-sync to fix audio hiccups. we really, really need fancy systems to sync to audio or do proper vsync (and rewire the snes resampler to forcibly adjust to a 60hz display rate) 2012-10-01 04:15:21 +00:00

goyuken 40d86d0a8b SNES: change the initial bootup frame size (on frame zero) to 256x224.

goyuken b6e4d9996e DCFilter: add a "push" mode more suited to being placed between a resampler and a metaspu
Gambatte: change the order of output from "GB => resampler => metaspu => DCFilter" to "GB => resampler => DCFilter => metaspu".
This doesn't change anything under most circumstances, except when playing the emulator in slow motion (for instance, 50% throttle).  There, the metaspu sometimes adds silence to the output, which isn't actually silence if it has a different DC offset than the audio it's being mixed with.  Well, 50% throttle sound output will always suck anyway...

goyuken a9304bef26 GB: memory domains now work correctly immediately after a loadstate 2012-09-29 13:03:14 +00:00
zeromus 3898733e8e nes-fix dmc sfx bug in bt&dd making nonexistent sfx; add emulation of empty databus (to extra joystick bits and reads of nonexistent EXP and WRAM memory ranges.. need to scan other emulator source codes for places to check for use of empty databus); fixes freeze bug in bt&dd. also break savestates, but add a crude version system so we at least have a way to avoid it in the future.
bt&dd has a glitch that reads from $6000 when there is no ram installed, and crashes if something too large is returned. I think this chooses a frame for abobo, and you can actually see abobo's sprites glitch for one frame right when the wall finishes getting busted down (the same place where bizhawk was freezing)

2) turn on Load GB as SGB from the GB menu.
3) load rom again.
To turn off, uncheck Load GB as SGB from the SGB menu.

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.

--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.

brandman211 e51b79e2fa -Flushed log after interrupt.
-Replaced subtraction with adding the 2s complement in instructions. That way, the Overflow Flag is calculated properly.
-Made it so that the masking of a result to 0xFFFF comes after calculating the Carry and Overflow Flags but before the Sign and Zero Flags.
-The CMPX instructions now use the aforementioned masking to properly calculate the Sign and Zero Flags even though the result doesn't actually get stored.

Thanks to this commit, IntelliHawk executes 1711 instructions properly. Next, it's supposed to take an Interrupt, which is bizarre because INTRM appears to be true at that point. This doesn't seem possible unless I am once again logging at the wrong time, hiding that the INTRM gets set to false before immediately switching back to true after taking the interrupt. Will look into this later.

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.

brandman211 5239b4f55b -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.

brandman211 0d20c133a5 -Moved the reset address to the CP1610 and made RegisterSP/PC private.
-Created helper functions for indirect ops; Indirect_Set will be needed for interrupts.

brandman211 e9a8980f0c -Throw exceptions for TCI, SIN, and BEXT.
-Added and logged INTRM, BUSRQ, BUSAK, and MSYNC.

brandman211 b83bb1901d -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!
