@ddoubleeasy try expanding your file system in raspi-config and reconfigure your input in emulation station.... maybe the hotkey got messed up

@LineOf7s Well then, probably the fact that my USB stick is formatted as exFat.
I guess I'll give it a break with Amiberry for a while.
Anyway, I am just updating my system, including the big one (second list item from the RetroPi-Setup Script). Given I get my PS3 controllers working on Bluetooth again afterwards, maybe Amiberry also behaves differently :-)

@Nikorasu081 I'm sure you already solved this but I found this very helpful when trying to understand what each remap/config files do what and in what order they are loaded.

@vahnxdean Login via SSH or get to a command prompt by closing Emulationstation. Open the File Manager (mc) and browse the /home/pi/RetroPie/roms folder, which will contain your ROMs and save states - under each system (nes, snes, etcc).
Copy/move the saves (they have the .stateX extension, where X is a number) to a folder inside /home/pi/ - let's say /home/pi/saves.
Configure the save states folder to be /home/pi/saves. This way the save folder will be on the SD card, but your ROMs will still stay on the USB HDD.
The reason you're not seeing the ROMs from the SD card is that Windows doesn't know how to read the Linux partition on it, and you're only looking at the /boot partition, which only contains the bare minimum to start the RPI system (kernel files and device tree files).

@flamingflareon Are you able to save from the RGUI ? You can save pressing Select+X, then using Save State. Does this work ? If it does not, then take a moment and give more details about your system - https://retropie.org.uk/forum/topic/3/read-this-first

That’s handy to know, when I moved my lad’s system from a zero to a pi3, I had issues with saves. Thanks

@dankcushions you were TOTALY right, I needed a BIOS but the one that worked the best for me ant let me save my game was the CPH 7502, thank you very much friend

before you all ask... 3 amp power supply (because contrary to Raspberry Pi's requirements 2.5 amps is not enough for anybody hence the lightning bolt in the corner for most people) 1200MHz overclock speed, and both heatsinks & fans cooling it.

@herb_fargus Oh sorry I did not know that this was also forbidden :-/ I edited it out

@Murderlol Ah, cool. Glad you got it sorted. Thanks for replying. It just helps others who search the forum with similar issues.

@turtlebear sounds like you accidentally changed the save slot (select+left / select+right).

ok i'll double check this tonight, but from memory I putted the right bios at the right place. I'll check the md5.

Thanks

Thanks a ton. I didn't even have to do the bindings because the disk control options are easily accessible in the retroarch quick menu. I found it by accident when I tried to figure out how to do it; turns out I was pretty close... The only thing I missed was that I was supposed to swap the disk input in between ejecting and closing the virtual tray.

Thanks so much for helping, you managed to find the missing pieces to my puzzle.

@FAB2TB SOLVED: My SD card has a writting problem, I cant format it no more which explain that I cant save anything on it correctly since it has been damaged.

Thanks for the tip. I just installed it and now it's "autosave completed!". Although the game won't load anyway for some reason :/
