What it says on the tin. Interestingly, with the 'new PPU', FCEUX fails in a similar (but not identical) way. These issues bring into question what I should be aiming for...why should I target 'old PPU' rather than the purportedly more accurate 'new PPU'? Are these movies not useful to me, depending as they do on an outdated PPU core? Over the long term, seeking total TAS accuracy might not be worth it.

WON'T FIX

Trying to run FCEUX movies turned out to be a minefield that depends just as much on FCEUX's quirks as arachNES's. I'm not interested in emulating how FCEUX improperly emulates the NES, so I'm considering this branch of the project to be an irreconcilable failure. I may still use this for testing purposes, but I'm not going to aim for making it work consistently. At best, I might end up adding functionality for recording movies myself. But it's clear that this is less feasible than I originally hoped.
