If we knew, that'd help. So far there's an added problem of feature-based randomness:
- skipping frames is bad. Forcing autoframe rate with a max speed of 1x and 0 max frameskip would be a solution, though hackish.
- step-by-step... completely breaks most movies. Unusable so far. Recording just 1 frame in step-by-step is enough to break movies for some games.
- and the last one I found, rewind states. When zsnes saves a rewind state, "something" happens and makes it go differently compared to if zsnes didn't save that state. Standard states do not seem to have that behaviour.

So, if you record a movie with 0 frames skipped, rewinds states set at 0, and never using step-by-step you'll never(?) desync. At least I never got a desync in ~500 test movies when using the same version of zsnes the movie was made with.

So what do you use to store the whole movie (like actions, state of the cores... something to ensure that the movie reproduces properly)?

Depending on how you store it, it can affect the movie. This would be the kind of issue that can cause the first two problems..

For rewinding (ideally, it shouldn't be allowed in the first place), it could be the savestate data (either incomplete or needs more data) or something fundamentally about the recording (which could be related to the movie data storage or the emulator processing the data) could be the issue.

I'll try to create a small movie and look into these issues...

.. Input. That's all we need. 'From a given state [console power up or save state - a constant status, basically] the same input ["movie"] will produce the same outcome [awesome].'
This is our goal, and we currently fail at it.

No.

For rewinding (ideally, it shouldn't be allowed in the first place)

Wrong person to talk about that, I'm a big TAS fan. You don't want rerecords, don't use them. But don't force people not to use them.

it could be the savestate data (either incomplete or needs more data)

Rewind states save a whole normal state (without preview pic, useless) plus 32 bytes not in save states. Check zstate.c to see for yourself.

or something fundamentally about the recording (which could be related to the movie data storage or the emulator processing the data) could be the issue.

This doesn't make any sense, sorry.

I never said I don't want it. I thought it was pretty difficult due to the nature of rewinding in the normal sense of the word... I should've thought this more through as a rewind in ZSNES is the equivalent of loading a savestate taken a moment ago.

About step-by-step/rewind, is it possible that the issuing the command itself being dealt with properly? Since you are dealing with input (this includes keyboard input) that this input is supposed/not supposed to be added into the movie? That's the only real issue that I can think of that could be at work.

Seems like 'something' else happens, since it has issues not present with usual states. But yes, you're right on the wanted effect.

Good idea, but it's not the cause. Pausing/stepping and rewinding is dealt with just before saving the input, actually.

Anyway, don't kill yourself over it.

Im sorry guys, i know i replaced the file in the zip with the newer version (because i did it manually...) but somehow it didn't take... DOS and the Source should be fine tho...

Uploaded a new binary, http://files.ipherswipsite.com/zsnes/ZSNESW_0227.zip

error message about mencoder.exe missing when mencoder is there but it seemed to work it just didnt output a file. .x264 codec and with sound in sync. (in nach's build you didnt have to specify its location you just had to have it in the same folder... do you have to with this build?)

didnt test other settings and never the less thanks nach, grinvader, pagefault and johnas quinn.

Hmm... was the Uncompressed AVI option removed intentionally? It's missing in this version (although the two new options are available)..

Assuming this build is good (I'm still not sure though), I'm not sure if the typo fix has been applied... because FF2/4 and CT are still affected from the DMA changes...

Otherwise it is still a good build...

I also fixed a bug with audio dumping in Windows.

ALL: Fixed crash after SuperFX savestates are loaded. [Jonas Quinn]

SDL: Fixed problem with GUI not being updated sometimes [pagefault]
SDL: Added freedesktop.org file [pagefault]
PSR: Parsegen now has better handling of blank comments. [Nach]

absoloutly awesome thanks everyone!

and ipher... are you sure this is the latest cvs? because it seems you have been having trouble lately adding the newest version to your site.

Looks fine, but the WIP name (and text file) should be dated 3/8/06 (as evidenced by the version number inside the emulator).

I don't think anything is wrong unless you find something wrong.

your right... in the left frame the date is one day early.

I'm having an issue enabling the NTSC filter in the new WIP (Kubuntu 5.10/Breezy). The checkbox is there, but nothing happens when I tick it. All other filters work as usual. I've tried in both O and non-O modes, full-screened and windowed. I'm using the flgrx driver (Radeon 9600), in case it matters. Is anyone else seeing this, or am I just missing something stupid?

I'm experiencing it too (I wanted to see this for myself), but I'm using the Windows version of the WIP.

Pity, I wanted to witness NTSC for myself, guess we're stuck with RGB for now!

movie recording, ntsc filter and date on iphers page are messed up in this version.

Do people read?

SRC: Added NTSC filter from blargg. [pagefault, ipher, Nach]

You can't use it, souce only.

What do you mean movie is messed up?

yea i overlooked src: so yea thanks for pointing that out... i'll also try to post bugs in the appropriate forum from now on.

Sorry, I didn't realize that something in added to the source wasn't in the source tarball that I downloaded/compiled. I'm apparently not the only one confused by that, though.

I think the fact that there was a toggle in the GUI options did throw me off... if it was hidden/missing.. I wouldn't have cared.

Has any work been done on open bus stuff? It'd be nice if I could play equinox in the latest version. There was a command line switch that pagefault told me but it did nothing. I reported it about a year and a half ago with my zuzma name. I didn't want to say anything about it since I don't like bugging you guys but I figure it's been quite awhile.

I believe there has, however whether it is complete or 100% working is probably a different matter. It's best to test it with the recent WIPs.. and if that doesn't work, well obviously.. it's probably not enough. I believe while some of that stuff was implemented, existing stuff has broke.. so, you'll need to find out for yourself.
