There aren't many movies done with FCEU 0.98.10 and I think all stay sync in 0.98.12. So, that version isn't useful but it would be a nice add-up to the museum. ;)
I think the only guy that may have kept that version is blip himself, maybe Bisqwit does have the source but I doubt it. I am afraid that version is lost forever.
The reason of being unkown by many people is that 0.98.12 version has been released somehing like 3-4 weeks after and 0.98.10 was mainly in beta-testing phase. And people were still using Famtasia.
Published movies done with 0.98.10:
Dragon's lair by Phil
Power Blade by Genisto.
I think there is also another one made by someone(Walkerboh?) but I don't remember what it is.
Also, I have started Legend of Zelda run with that version but finish it with .12.
As for Snes9x 1.42, the scenario is similar except that 1.43WIP1 was released ~4-5 monthes after.
So, there is even higher chances that someone still have it.
All my published SNES movies are done with 1.42 if I remember correctly.
And some people have done movies with it.
Also the
source code for FCEU 0.98.12 is still available.
Also, it is a good idea to create such page. However, I would put all rerecording emulators, accepted or not.
