These N64 cores worked correctly in the previous version of muos, but currently do not start in Rg35xxh. This was tested from a clean installation. The cores start and immediately return to the ROM screen (RetroArch crash).
Unfortunately LudicrousN64 does not like auto save/load states. You will need to set an override specifically for this core to not allow that.
As for ParallelN64, this has been updated. You can remove and download the Nintendo 64 package from the Core Downloader.
I reinstalled the core archives and updated the os to last patch of jacaranda. but ParaLLEI still not work (the core version is 2.0-rc2)
