!!! Introduction .fcm files made with older versions of FCEU may desync on FCEU.28. This page describes a brief history of older FCEU rerecording versions and sync differences. All older versions are available in the downloads section. ! FCEU.12 This was the first widely used FCEU rerecording branch. TAS features were implemented by Blip. Nearly all NES TAS movies made in 2004-2005 were made with this version. Note: If capturing AVI's of these older movies, use the AVI capture fix version of .12 ! FCEU.13 Many new features added by Nitsuja. However, some sync differences were introduced. Some movies (such as Dragon Warrior 4) made with .12 no longer synced. ! FCEU.15 More new features/enhancements/bug fixes added by Nitsuja. There maybe some sync differences between .13 and .15. Few movies were made with .13 since the .15 release was so soon after. ! FCEU.16 New TAS tools added by luke including basicbot & memory watch. However, it introduced sync differences compared to .15 This was the primary version used for many movies in 2005 & 2006. ! FCEU.17-FCEU.28 All versions of FCEU (.17-.28) should have the same sync. FCEU.28 is the last version made as the project was abandoned in favor of FCEUX.
