Hello. I have a raspberry pi model b and I can not run colecovision & wonderswan. I can not understand what emulators use for this, and whether the BIOS images? Have you run these platforms? Sorry for my English I am a foreigner
Instead of writing down a book of instructions, i put together a quick folder with everything needed to set it up. The core is already pre compiled so all you have to do is follow the folders and instructions i put inside. If you need any more help feel free to let me know.
As for coleco i haven’t played around with it, so i can’t help you there.
If in the future you would like to compile your own core “.so” this is the steps i took.
sudo apt-get install -y git
git clone https://github.com/libretro/beetle-wswan-libretro
sudo mkdir /opt/retropie/libretrocores/lr-mednafen-ws/
sudo cp mednafen_wswan_libretro.so /opt/retropie/libretrocores/lr-mednafen-ws/
I’m not sure if it works with zips or not. You might have to edit some information to match your theme. I just made ngp + color = ngp, same as wonderswan, i didn’t separate them since i was just testing it and setting it up for the first time.
edit: if you need help setting it up separately just let me know
You would have to edit the system.cfg, make a another rom folder, and add a config with in the opt.
