SDL Retro
Two options for using SDL Retro are available: All-In-One and One-By-One. As the first of these includes all default SDL Retro cores in the OPK file itself, all the user must do to install it onto their FunKey S is add it to a folder at the root of the device's file system just like any other application, emulator, or game. Should you prefer to only have the emulator cores you intend to use installed, and thus speed up the SDL Retro's core selection process, you may alternatively download the One-By-One option. While its download also includes an OPK file, the emulator cores themselves are included in a separate cores folder that must be placed in the /mnt/FunKey/.sdlretro file location of the FunKey S for SDL Retro to function. If one or more required BIOS files are listed alongside a core you wish to use, ensure that those files are named and located in the /mnt/FunKey/.sdlretro/system file location for optimal emulation results. In the case of blueMSX, download, extract, and place that emulator's Databases and Machines folders in the /mnt/FunKey/.sdlretro/system file location. In the case of Neko Project II Kai, the required PC-9800 files listed in the table below should be placed in the /mnt/FunKey/.sdlretro/system/np2kai file location. If you don't see the .sdlretro folder, your computer's Unix-based operating system is hiding hidden folders.
