SNK Neo Geo Pocket

The Neo Geo Pocket is a monochrome handheld game console released by SNK. It was the company's first handheld system and is part of the Neo Geo family. It debuted in Japan in late 1998 but never saw an American release, being exclusive to Japan, Asia and Europe.

This system scrapes metadata for the “ngp” group and loads the ngp set from the currently selected theme, if available.

No Neo-Geo Pocket emulator in Batocera needs a BIOS file to run.

Place your Neo-Geo Pocket ROMs in /userdata/roms/ngp.

RetroArch (formerly SSNES), is a ubiquitous frontend that can run multiple “cores”, which are essentially the emulators themselves. The most common cores use the libretro API, so that's why cores run in RetroArch in Batocera are referred to as “libretro: (core name)”. RetroArch aims to unify the feature set of all libretro cores and offer a universal, familiar interface independent of platform.

RetroArch configuration

RetroArch offers a Quick Menu accessed by pressing [HOTKEY] + South button (B SNES) which can be used to alter various things like RetroArch and core options, and controller mapping. Most RetroArch related settings can be altered from Batocera's EmulationStation.

Standardized features available to all libretro cores: ngp.videomode, ngp.ratio, ngp.smooth, ngp.shaders, ngp.pixel_perfect, ngp.decoration, ngp.game_translation

libretro: Mednafen_ngp

Batocera uses the standalone port Beetle NeoPop based on Mednafen. Mednafen's Neo Geo Pocket emulation is based on NeoPop.
