@markyh444 AFAIK there is no source code available - just the pre-installed PI image. It uses RetroArch + the MegaDrive cores and it looks like the image is based on Raspbian, so if the author wants to give permission to re-distribute or releases the source code under a distribution permissive license, it might be possible to add it as an alternate front-end.

The limbo16 project is a 3rd party folders-support add-on for the blast16 Raspberry Pi emulator front-end: https://sites.google.com/view/limbo16/

@mitu Of cours, but then you mess up your rom set. On the other hand some systems or naming conventions use rom sets which have names which are not unique. (I don't find one at the moment, but i saw such discs) e.g. "<Game>.cue" "Track1.bin" "Track2.bin"

Wow, that was fast! Thank you @mitu

@pjft Thank you kindly, sir. The warm welcome means a lot, but there's no need to worry. I'm still somewhat swamped until after the holidays, but I do plan on keeping a tab open here to help out with the most recent round of spammers. Those guys are relentless.

@oldversions it's a request for help so it goes in help and support. I'll move it. You can install whatever parts of retropie you like https://retropie.org.uk/docs/Manual-Installation/

@fluffypillow Thanks for your fast reply.

Installed the image last night, started loading my ROMS manually also. I like the concept of the naming conventions and they way the lists are pre-generated so dropping a ROM in with the correct name, they just appear. I changed to Robospin_v4 on the main screen as I didn't like the up/down movement go left/right.
