Overview

Watara’s Supervision (1992) is a portable 8-bit rival to the Game Boy. REG-Linux groups the console under supervision so the right theme art shows alongside the system.

Technical specifications

  • CPU: 65SC02-compatible 8-bit processor running at 4 MHz.
  • Memory: 32 KB system RAM backed by 8 KB video memory and cartridge ROM banks.
  • Display: 160×160 pixel LCD with four shades of gray and hardware sprite blitting.
  • Sound: Mono speaker or headphone jack driven by a single square-wave channel.

Quick reference

  • ROM folder: /userdata/roms/supervision
  • Accepted formats: .sv, .zip, .7z
  • Emulator: libretro: potator
  • System group: supervision

ROMs

Place every Supervision cartridge dump into /userdata/roms/supervision. Use .sv files whenever possible, since the emulator recognizes the platform-specific format directly.

Emulators

RetroArch / potator

libretro: potator is the recommended core. Open the Quick Menu ([HOTKEY] + south face button) to tweak shaders, ratios, or controller mapping. Use the EmulationStation options for supervision.videomode, supervision.smooth, supervision.shaders, supervision.pixel_perfect, supervision.decoration, supervision.gfxbackend, supervision.audio_latency, and supervision.video_threaded.

Controls

The Supervision uses a D-pad plus two buttons and a Start key. Map those inputs via /remapping_controls_per_emulator when the defaults don’t match your pad layout.

Troubleshooting

  • Make sure every ROM uses the .sv extension; zipped ROMs should only contain the needed file.
  • Switch between OpenGL and Vulkan (via supervision.gfxbackend) if you see rendering issues.
  • Consult the generic support pages for additional help.
