I've just attempted to submit a ZMV for a TAS submission (Run Saber) but the upload script is rejecting it, saying the movie begins from a snapshot. I know for a fact that it does not ("Record from power-on" has always been checked in my movie options) and I was wondering if perhaps this issue is due to the movie being made with ZSNES 1.51 instead of the 1.42 that the site suggests. Anyway, just wanted to get this out there. (And if ZMVs aren't actually accepted, I haven't seen any indication of that.)

According to this no one has ever submitted a zmv to the site, so I wouldn't doubt that the submission script may not be working. You could try to email it to Bisqwit to see about getting it on the workbench, but I have to warn you that since you chose an emulator that not too many people use, unless you chose a totally kickass game, it probably won't get much attention. Oh, and that page says ZSNES support is tentative. Whether that means we're just waiting for someone to submit a movie to make it approved or it's not fully accepted yet still has to be seen (I'm not sure).

Perhaps someone (Nach?) can spot an error in this code? http://tasvideos.org/Sandbox.html#ZmvSource

Is it possible that the ZMV that's trying to be submitted starts from power-on without SRAM clear? That gives 10 instead of 11 at 024x byte 0 and 1, which would fail in this source code, but might still say "starts from power-on" when loading the ZMV file.

Don't suppose you want to upload the movie file somewhere else so we can check what might be causing it?

That's it exactly. I wasn't aware that Power + SRAM Clear was necessary. Any way I can fix this without redoing the entire movie?

I look at your file from this post, and position 024 is set as 04h = 0000 0100. The last two bits being 00, according to ZMV.html, are "start from savestate". Is the format different between 1.51 and the previous version? Maybe ZMV.html needs additional documentation. If it turns out that you did in fact have a setting wrong, you could poke whatever value is needed with a hex-editor, and see if the movie still syncs. But if the "dirty SRAM" present caused any subtle changes in the game's processing, you may have to redo portions of it in order to submit it.

I can't see the "dirty SRAM" being any sort of problem, because Run Saber doesn't even use it (SRAM) as far as I'm aware. I'll take a look after work and see what I can do. As for differences in .ZMV format between v1.42 and v1.51, no idea. I'll try playing my Run Saber run in 1.42; if I'm thinking this through right, it working would prove there aren't any.

You won't get it to sync in 1.42 because 1.42 and 1.51 have differences in emulation.

Okay, I've done some looking around using XVI32, but all I managed to find out for certain was that the start type is NOT stored at hex 24 anymore; it was value 04 every time. I did have a brainstorm, though; I did two 1000-frame, no-input ZMVs of Run Saber, one from power, one from power with SRAM clear, in case someone wants to take a look. http://fast.filespace.org/Keita-chan/Run_Saber_ZMVs.rar http://www.filespace.org/Keita-chan/Run_Saber_ZMVs.rar http://rapidshare.com/files/71820969/Run_Saber_ZMVs.rar I also made a list of where the hex values differ in each of them; there weren't many spots. 
Hex 9

Power:F5
SRAM :ED

Hex D

Power:04
SRAM :00

Hex 11

Power:88
SRAM :00

Hex 12

Power:02
SRAM :00

Hex 27

Power:80
SRAM :C0

Okay, I've redone the movie with recording beginning from power with SRAM clear, and I tried to submit it again just now. It's still giving me a "begins from snapshot" error. At this point, I figure it must be because of ZMV differences between 1.42 and 1.51. http://fast.filespace.org/Keita-chan/solon-runsaber.zmv.zip http://www.filespace.org/Keita-chan/solon-runsaber.zmv.zip http://rapidshare.com/files/74134494/solon-runsaber.zmv.zip

Thanks a lot; that's exactly what the person who keeps the ZSNES code updated needs to know. Now, it's just a matter of figuring out who that is and asking him nicely to implement it.

Okay, it should work now, if not, let me know.
