The Pocket Challenge v2 is a Japanese handheld device released in 2000 by Benesse, a publisher specialising in education and correspondence courses. It was not sold as a game console but as a learning companion for students subscribed to the company's programmes: revision, quizzes, vocabulary and English exercises, with a few more playful titles.
The hardware is directly derived from Bandai's WonderSwan: same NEC V30 MZ processor, same 224x144 monochrome screen, same remarkable battery life on a single AA cell. Only the case and the control layout differ, tailored for schoolwork rather than gaming. That kinship is precisely why a WonderSwan emulator can run it.
The device was never sold outside Japan and all of its software is in Japanese. Its library is tiny and its interest today is essentially that of a curiosity, but Recalbox handles it as a system in its own right, with its own roms folder.
Emulator availability per board:
| Emulator | RPI3/RPI02W | RPI4/400 | RPI5/500 | OGA/OGS/RG351 | PC | RG353 |
|---|---|---|---|---|---|---|
| Libretro Mednafen_WSwan | ✅ | ✅ | ✅ | ✅ | ✅ | ✅ |
The Pocket Challenge v2 is available on every board supported by Recalbox.
Mednafen_WSwan is the only emulator for this system and therefore the default one: it is the very same core used for the WonderSwan, the hardware being almost identical. Its compatibility is excellent. It supports neither netplay nor softpatching, but it declares support for CRT display. RetroAchievements are not available on this system.

Supported extensions: .pc2 .zip .7z
The expected format is .pc2, specific to this system. .zip and .7z archives are accepted, with a single game per archive.
WonderSwan (
.ws) and WonderSwan Color (.wsc) roms do not go here: although they use the same emulator, these are separate systems, each with its own roms folder.
