Mupen64 latest core problem with Ocarina of Time

Hello, I have a big problem with the latest mupen64 core. I only have this problem with a specific game: it is in The Legend of Zelda: Ocarina of Time. The problem is that when I hold Z and press A… Link does a very weird Sidehop. Normally, link should roll. Also, the sidehop goes to the right and is not normal, the sidehop has no animation… The only way I found to fix this is to downgrade the core to the older one that was made in May 2014. Anyone has also this problem and is it possible to fix it ? iOS 8.4 jailbroken.
