Unable to convert .gmv to .bk2 - Null Core

[Meerkov]

Tested in 2.9.1 and 2.8

1) Load El Viento 2) Try converting the .gmv from tasvideos to .bk2 using the "Import" menu. 3) Try loading the movie (various ways, drag an drop, open in TAStudio, etc) 4) Warning about a null core, then a null reference exception is thrown and it gives up.

For whatever reason, this does work 1) load El Viento 2) Drag and drop the .gmv movie into 2.9.1 3) Then open TasStudio

This doesn't throw an exception, but trying to convert from .gmv to .bk2 first does.

CNR on 2.9.1 or master at ac3913ded. Rom hash is SHA1:B53E9017... and I presume you were using this movie.

Socket (U) [!].zip Here's another old Genesis movie that I can't seem to get converted.

In this case, the behavior is a little different, but similar. The converted .bk2 seems to have no input log key, and crashes if you advance 1 frame.

Trying to open in TasStudio throws this error forever until you force quit

[Meerkov]

I was able to eventually get it working by manually fixing the Input Log file, as the conversion only converted controller 2 to a 6 button input, but not controller 1. And as a result the input file was totally messed up.

Can also not reproduce.

[YoshiRulz]

The Socket sample failed for me.

edit for future humans: This hasn't been fixed as of beee1eb82065cf0d840b65de8fcc84ded73a6d58. It should be as simple as widening the 3-button part if the other is 6-button.

[Morilli]

Okay that's apparently due to the importer (correctly) importing the first controller as 3-button controller and the second as 6-button, which is not supported by the sync setting that toggles 3/6 for both controllers.
