I'm having an issue with Mupen64-Next. It only affects Mupen. All other cores work fine.
I start HBL using redirects in Atmosphere. I load Retroarch, load Mupen, and load content. It seems as though the first time I attempt to load content after first starting RA, content will load perfectly. Once I'm done playing and want to play a different N64 game, it will not load the content and only display "Failed to load content". If I exit out of RA and HBL and perform the steps to reload HBL/RA, I can then load a game again.
Likewise, if I attempt to load content before loading the core, it will always fail to load content.
No other core acts this way. Is this a known bug?
