I’ve managed to get wonderswan working on my rpi2, ill make a guide for you once i have some time.

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.

cd
sudo apt-get install -y git
git clone https://github.com/libretro/beetle-wswan-libretro
cd beetle-wswan-libretro
make
sudo mkdir /opt/retropie/libretrocores/lr-mednafen-ws/
sudo cp mednafen_wswan_libretro.so /opt/retropie/libretrocores/lr-mednafen-ws/

I just set up neogeo pocket a couple of hours ago ironically. If you would like me to upload it like wonderswan, let me know. I also agree with it should be part of the project as well.

Runs well on an rpi2, not sure about the older version. I’m hoping to learn more about compiling the cores, so i can compile them specifically as performant as possible.

Edit: just uploaded the neogeo pocket, i compiled the core the same way as the above method.

No problem.

Like the other zip, i added a readme that should have the appropriate system info which you can just copy and paste into your system.cfg

No problem.
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.

Good Work, from your comments I’ve added two pull requests to have these emulators added to the experimental menu

WONDERSWAN:
https://github.com/retropie/RetroPie-Setup/pull/849

NEO GEO POCKET:
https://github.com/retropie/RetroPie-Setup/pull/850

I’ve tested them on my pi and they seem to have worked but it’s possible the code could be potentially improved (I’m not the most proficient at coding yet) hopefully they will be merged soon.

Any idea on why the .sav get saved in the bios folder instead of the folder the game is launched in?

Edit: I also re uploaded the folders with the appropriate files for wonderswan classic and color. In case others wanted it separate and to be similar to the gameboy and gameboy colour.
