@thomthumb The newer versions of MAME can emulate Tamagotchi devices, but I'm not sure about Digimon. If not, new LCD games are being added all the time, so it may just be a matter of time. As far as RetroPie is concerned, running the newer versions of MAME would normally be a bad idea, as performance would be terrible. However, LCD games like these might not demand as much to run well. It'd be a great experiment. Here's an article discussing the games being added to MAME's repertoire and below is a video to see a few of them in action.

Thank you very much!

@xvo Reicast doesn't have BBA emulation support. Demul on Windows is the only DC emulator that can play online, as far as I know. There are premade disc images for Sylverant called PSO DC Ives Pack 2.0. They're all bugfixed, online and offline capable and ready to go. Not linking them here, obviously. I'm sure there are other private servers out there too.

after moving all the.sh files and re writing the paths it all works now doom and all the other classic fps games are all now one system complete with logo

Just put some decent kits together, create PDF/video guides on how to install Retropie, how to put ROMs on the system and all the other basics. Don't forget to use homebrews for examples and mention that using ROMs of games you don't own, or BIOS of systems you don't own is illegal. Give credit to RetroPie/homebrew developers. Doing this I think you are in the clear.

I have updated this method as well as updated the comic book theme to support custom systems. @meleu has also create a very nice linking method as well. If you are interested see the post here which provides directions and links to both methods. New Comic Book Theme!

Panic over everyone. I run an ls -a on the folders and found the cause of the problem, the files were hidden with a "._" prefix making them hidden. Removed all those and the system returned to normal. Thanks all.

@herb_fargus Its an idea but I do not have any spare usb drives.

Thank you for that super-fast reply! I was looking at gparted but hadn't managed to get onto it around work - but that auto script seems to be just the ticket! I'll give it a crack and come back if something goes horribly wrong - if it doesn't we can assume this thread is closed :D

@edmaul69 Worked. Thank you.
