Hello, thanks for the advice : I bought myself a new Hard Drive (Samsung Station D3) which has its own power provider. The problem occurs very less, but it still does (just for you to know, I formated the disk in FAT32 and removed any "sleep mode" function on it, the disk never gets to sleep, as proved by the lights on it). I guess my problem might have been a combination of settings forced (which I don't anymore), using of loader (now I directly use Nintendont), old storage (problem solved)... and maybe a little bug in Nintendont time to time...its probably the device your using then, if your not forcing any setting and all games randomly freeze on nintendont 373 then something is wrong with your storing device, even if there is a new rev it will be to do like small addons and such it will never be a totaly remade code or something.
For example I just spent the last hour playing Eternal Darkness without any problem, and the game just "paused" right away (no, it's not my safety meter lol !)
Thanks for your message anyway, since my storage must have had something to do with it : I hope next releases of Nintendont will be even more stable than they are now. Regards
