If your like me and your bad at the ssh and all of that stuff, but you want to play some game on the pre-existing emulators via the retro games tab, then your in luck! Welcome to the how to install roms. (the easy way.)
Download Filezilla, this is a way to remotely access your gameshell or raspberry pi’s files.
(Download it at https://filezilla-project.org/ don’t worry no viruses here)
Connect to your gameshell, type the ip into the ip section and the user and password (if you haven’t already changed them) are both cpi the port is 22. (To get your gameshell ip open tinycloud.)
Once it connects, you should see a folder called games, click on it then click on menu, then gameshell then 20_retroganes (something like that) and you will be greeted with three folders, Mame Mgba and Nestopia (I can’t get Mame working so good luck with that.)
Select the emulator of choice then from the roms in, Nestopia uses .zip files with the rom inside and Mgba just uses the rom by itself, no folders.
Once you have uploaded your roms go on your gameshell, select retro games and then the emulator, and if there are no roms press the scan button and your roms should appear.
(If the roms don’t show up tell me in the replies section and i will see what I can do)
I hope this guide helped the people like me who can’t use ssh very well and want to actually enjoy their gameshell instead of tossing it aside because they can’t get any roms on it.
