ZSNES board

How do you stretch an image vertically by 1.2 with alternating lines of the image and black, without it looking like crap? Also, notice how the resulting NTSC image has been stretched by 3:2.4 = 1.25:1, where the proper stretch is 1.141:1

Nope, there's some kind of protocol mismatch and I don't know how to solve it. Result: lost opportunities. Oh well.

Oh well, I didn't communicate clearly, sorry. Nevermind.

This is what byuu's response often feels like when I try to simplify things without eliminating anything essential: http://h1.ripway.com/blargg/temp/complexity2.jpg Maybe it's because I'm overstepping things and stepping outside my "territory". Still, it's discouraging because it almost se...

I still think the audio resampling and vsync can use some refinement. I've come up with a simpler conceptual model for thinking about this resampling, which I think would make things clearer for everyone. First, consder how many samples and frames the SNES generates per second: One second |---------...

I remember the problem I was having with automatic synchronization adjustment: the program would get fooled when occasional random processes took lots of time (like more than 1/60 second) from the emulator. No matter how much it adjusted its "skew", such occasional interruptions will alway...

Slowed SNES: 60 Hz video, 31992 Hz audio Then we just resample the audio to 48000 Hz. There's no need to resample twice, from 32040 to 31992, then to 48000, so we just resample once from 32040 to 48000 Hz, using an interpolator rate (step) of 0.6675. Wait, you lost me there. Wouldn't you have to re...

Screen saver kicking in?

A skew of 32200hz, means that your emulator is running ~0.5% (less than one percent, in other words) faster than a real SNES would. Every 4-5 minutes, the emulator will be one second more ahead of where a real SNES would be. If the PC's display is running at 60 Hz, and you're synchronizing smoothly...

I suppose that would work, but it's unconventional and inefficient since it involves a divide. Generally the fixed-point unit is a power of 2, allowing a right shift to convert to integer. To convert to fixed-point, shift floating-point values left by the number of fraction bits (that is, multiply b...

While explaining the subtleties of linear interpolation of an unending sample stream to byuu, his preference for resampling immediately rather than buffering it as I usually do prompted this absolutely simple and correct implementation of linear interpolation. It would of course use fixed-point (all...

Once byuu gets linear resampling working well, I'm going to send over a fast polyphase FIR-based resampler, which is the same thing SRC uses.

Try a rip from a different place. Some of them have corrupt DMC samples that keep looping.

Yours looks a bit better, as you require the caller to specify the buffer to write to. I don't know if it'd help much to tell the resampler that it'll be working with blocks of n samples or not. Maybe, maybe not. Yes, returning a pointer to an internal buffer is just asking for trouble, since the c...

Can we adjust the interface a bit, for efficiency/simplicity? Basically, I'm thinking you don't need "samples_pending", just a way to read as many samples as are available into the caller's buffer. class Resampler { public: // Sets output sample rate and removes all samples from buffer voi...

I pulled my SNES out of a box, after having been there since my first post. I was opening it up and remember this, so I turned the power switch on to discharge the capacitor and the power LED turned on for a moment. It was still charged after all that time!

Sorry, you're wrong:

How much latency does it introduce? Latency isn't an issue when there's no interaction with the source material.

Applying gamma correction isn't exactly color science; in fact, it's applied equally to color channels, so even someone with no color vision would stil see the proper effect.

Breakfast? That's unsustainable; try this instead: kitten huffing.

Graphics work more simply, and the main functionality is used by most games. Sound chip behavior is more intricate, more "maze-like", with areas used by some games and not others. Sound hardware also differs quite a bit between systems, so it's less predictable and requires more reverse-en...

That's redundant; bricked is permanently unrecoverable.

2 gigs in 20 minutes of leaving the menu sitting? Wow. If it wasn't just you, seriously, don't you think the forum would be half filled with complaints about that by now? Who is to say this isn't an issue that only shows up on a small number of machines? Software is complex and can have behaviors w...

heck, hardisk was made with somewhat similar addressing calculation as memory card does... Its size is dictated primarily by the disk, which isn't related to a power of 2, rather the data density and area of the platter. The capacity of a solid-state memory chip is almost always a power of two, and...
