Re: changing disks
Are there any games that would need to change disks more than once?
Also, do multi disk games have different game IDs for the different disks?
Not being able to call gui code from the core is complicating this, but worst case i can always just pause the game, and tell the user to switch disks manually.
edit: got my answer: no to both.

Basic disc changing support. It currently just saves when you change disc, then when playing back pauses emulation, and prompts the user to switch discs. I'm not really sure how to go about automating this.
Maybe i could save the name of the second iso to the header...

A tip is to look at how PSXjin does it for PlayStation, perhaps this can help you gain a basic idea of a good way to implement this. As far as I know in PSXjin you have to pause emulation, then load the other iso, then resume.
I looked at this a long time ago, so I don't remember any specific stuff. I can probably take a look at it again if you run into a brick wall.
Could someone with a multi disc game test this and make sure it works and syncs? https://dl.dropbox.com/u/11111638/Dolphin%20changedisk%20x86.exeFor now, the second disc must be saved in first iso path (the first thing listed under iso directories in config->paths).
Thanks for the tip warepire, i found something there that helped.
Disc switching is (hopefully) done. The .iso name is saved to the end of the header (switching discs more than once is not supported, but it's my understanding that this should never need to be done), and when playing back it will search all set iso folders for it, and automatically load it if found, or prompt the user to manually switch discs if not.
If someone can just test that it syncs, i'll merge it.

Fixed an old bug where the header wouldn't be fully read when loading a .dtm from anywhere other than when starting emulation. This mainly happened if you started emulation without a movie, then loaded one later, and caused things like start time, and most of the new stuff i've added to be zeroed.
Author name is also now maintained when saving a .dtm, if you hexed it in previously.
Everything but the disc switching, and other stuff i mentioned in my last post. I'm double checking my code now, then i'll commit it shortly.
edit: just committed it.
edit2: don't use 3.0-785. I I forgot to adjust the padding in the header. 786 fixes it.
Thanks!
Little problem, though. Whenever I try to playback a recording, it ends the movie at the first frame and gives the error:
"Fatal Desync. Aborting Playback. (Error in PlayWiimote: 4 !=23, byte 315.)"
Any ides how to fix it? Google and dolphin forums revealed nothing. Never saw this on the old builds.

On "Dolphin[desync-fixes]3.0-382-dirty_x86", Mario Galaxy 2 has many desyncs.
As well, there are many savestate/loadstate errors. Since it happens 1/10 of the time, making a TAS for Wii games is very much difficult.
I hope that, with savestates being improved on "Dolphin_dtm-config_x86", I can (eventually) make TASes on Wii.

So then. On version 3.0-382 only, it is possible to replay movies using the Wiimote, but it is very strange.
Games that use the Wiimote only seem to have no problem, but games requiring Nunchuk (attachment) or other controller cannot be done. It will desync randomly.

I only tried to see if the Nunchuk has any effect on Mario Galaxy. There is no problem.
For New Super Mario Bros. Wii, there is no problem of desync so it can be TASed, but there are a lot of errors.
I understand that it is necessary for something like TASinput to use the Wiimote. With only the keyboard, it is not possible to fix a specific value along the X,Y,Z axis for games which require such special motion.
In Wii party, there are minigames that cannot show special motion.

asutoro, you can try using a hex editor to edit the dtm to have a specific value. Though you will have to replay the movie again and again, but it works at least.
