Hi ! I've got a problem... I'm making a VERY long run since some months, and it appears that after you beat a boss, you have to save to continue. ... I did this run without memory card. Is it over ? I can "insert" a memory card, save and continue, but will it be read by the emulator when playing back the movie ? Please, I need your help... You know how long and hard can a 3d game TAS be, I worked on it since September, I don't want to redo anything :|

Eh? What game is it? Surely it doesn't require a memory card to continue.

Yeah, if you say what game it is, I'd be happy to look at it to help find an alternative. I have nothing better to do ;)

Seems legit.

Billy Hatcher And The Giant Egg, I'm playing an all level run, so I have to do the level after the final boss of Giant Palace. After this boss though, the ending credits arrives (can't skip them...), then the game ask me if I want to continue without saving, and then it just restart... If I have a save, it works perfectely, else I'm stuck

Oh.. Is it not possible to hex the start to include a memory card? If not, i can hack something up for you, but if you can hex it, that'd be the best option. Also, next time don't start a tas without planning everything out, and testing the route!

I never played the game without memory card, I didn't even doubt this would happen. I will have to hex every part where they ask for a memory card, but if it should be faster than redoing the whole run. Thanks for the help :) EDIT : I can't hex-edit actually, there are tons of stuff which are frame-dependent on this game :( I'm uploading the movie + 2 savestates (one before the credits, one after) so you can see by yourself.

http://pastie.org/5628393 should do what you need. You'll have to hex the movie though, since it doesn't record mc changes. It'll be bit 6 of the second byte of the controller data. I can compile a build for you if you need, just let me know if you need 32 or 64 bit. Keep in mind, you're movie will be unplayable without this patch (or i guess someone could just manually connect the mc during the credits, but who wants to do that?).

Just as a note, I'm using the build 828. Can you compile this for 64 bits please ? :D How do I hex edit that ? When I need the memory card, I change the 6th bite of the 2nd byte of the controller to 1 ? Also, can I do that with a simple hex editor or should I use another tool to modify bite-specific ?

What's the revision number of the build you're using? It's listed in the about menu towards the top. And yes you can use a hex editor. Just set the second byte to 0x20 (32 in decimal).

Made it work ! Thank you so much ! :D EDIT : or not, I can record a save and then continue by modifying the second byte to 20, but when I play back the movie it just ignores the save... I don't know why. I'm going to continue testing :p By the way, do I have to delete the memorycard in user/GC each time or is it ok to keep it ?

Ok, when you wake up I'll need your help... When I put 32 instead of 20 on HxD, Dolphin tells me "Invalid file" infinitly (I have to force quit it). It was working better with 20 :p I really don't know what to do. EDIT : Oh, ok :p I'll put back 20. EDIT2 : Made it work... I just have to put a HUGE delay so the playback could actually load the memory card... (it seems it's not frame precise). Thank you so much RachelB ! :D

Oh, yeah, sorry, i should have mentioned that it won't switch the memory card right away. I'm glad you got it working. Also, if you could not call me rog anymore, i'd appreciate that!
