HLE: Boot error: elf not found!

Please post a screenshot of your /dev_hdd0/game/BLJS10154 or /dev_hdd0/game/NPUH10032 folder

Also, don't expect that those games will be Playable, because they won't at this stage of the emulator.
Unless you want to help with testing or providing results / reporting issues, there's no reason you should try to play those kind of games just yet. Try smaller ones like Sonic or the other Playable ones.

I think Sonic CD is broken currently. Should probably be retested.
