Re: Timing the change in rendering status
I also observed the same behavior in my emulator and fixed by delaying ppu updates following a register write by one cycle. Here's the comments I have in my code: //Battletoads will enable rendering at cycle 255 and break sprite 0 hit (because vertical update happens on cycle 256 and misaligns the b...

Re: MC-ACC (again)
this seems to indicate emulator experimentation relative to understanding of MMC3, rather than hardware evaluation of some kind. This was based off of logic analyzer measurements. I don't know why the image doesn't show up in the original post anymore, but here it is: http://nemulator.com/images/MC...

Re: Using Windows on a Mac? Or should I just buy a Windows c
I run Windows 10 exclusively on my MacBook Pro (Retina/3rd gen) and I've had no issues at all. I love the combo. I also have an older MacBook Air (I forget the specifics) that almost works fine. The trackpad infrequently doesn't work on resume, requiring a reboot. Fortunately, it's been relegated to...

Re: Mesen - NES Emulator
I'm not too sure what nemulator syncs itself against, though (e.g vsync or a timer). vsync, by default, but a timer can be used as well (especially useful for gsync/freesync). The only thing Mesen does at the moment is force the Windows-wide timer resolution to 1ms (only while the emulation is actu...

The fix addressed in this thread is only for the areas shown in the video. There should be no shaking outside of those areas.

Towards the end of the first level, when cannonballs are falling from the sky, and in the second level, when it starts to vertically scroll. Maybe more afterwards, but I've never made it past there.zeroone wrote:Which part of the game shakes?

Re: Bill & Ted's Excellent Adventure successive writes
Immediately on startup. You won't even see the title screen if you're not handling successive writes properly.

Re: Your NES emulator of choice?
I guess I'll throw in a vote for my own emulator. The a/v sync (no scrolling glitches), the upscaling filter, and the lack of save states (yes, that's a feature) are what I like most about it.

Re: Aladdin (Super Game) mapper 4 bug?
If Nintendulator is using the old behavior, then Star Trek - 25th Anniversary is supposed to not work correctly... Yet it does. What part of the game supposedly fails to work? Unsure if there are other issues, but garbage flashes on the screen right before the dialog boxes scroll into view. But thi...

I suppose it could just come down to the palette that's used, but here's what my emulator looks like with emphasis bits enabled:

Re: Aladdin (Super Game) mapper 4 bug?
Took a quick glance at Nintendulator's source code, and it appears to be using the old IRQ behavior.
Zepper -- the green title screen is emphasis bits related. If I disable emphasis bit support, I get the same result.

Re: Aladdin (Super Game) mapper 4 bug?
It was hanging in my emulator as well, but I was able to get it to work by forcing the "old" IRQ behavior.

Re: A/V synchronization
The only "issue" with audio_sync.exe I can reproduce is when clicking the application window and/or dragging it around. Sometimes it doesn't re-synchronise, resulting in never-ending desynchronisation (clicking/stuttering), and the green gradually either decreases (i.e. keeps decreasing i...

Re: A/V synchronization
Thanks for the help James! I just tested your example today, and the sound seems to be smooth most of the time, but I can hear some clicking after a few seconds. I just recorded the output of the program and this picture shows some changes on the shape of the wave: http://i.imgur.com/17RdoEn.png I ...

What are you using to record the output?
