First pre-built release of vis_warp barrel-distortion on the Williams arcade core. No Quartus needed — drop-in, pre-named to just work.

What's here

  • RobotronVIS_20260528.rbf — the vis_warp core
  • Six (vis_warp) MRAs: Robotron 2084, Joust, Stargate, Bubbles, Splat!, Alien Arena (all run on the one rbf)

Install (no renaming)

  1. RobotronVIS_20260528.rbf/media/fat/_Arcade/cores/
  2. the (vis_warp).mra files → /media/fat/_Arcade/
  3. your own MAME ROM zips (robotron.zip, joust.zip, …) → /media/fat/games/mame/
  4. MiSTer menu → Arcade → "Robotron 2084 (vis_warp)"

The MRA's <rbf>RobotronVIS</rbf> auto-matches the rbf — nothing to rename, no collision with vanilla. HDMI tip: leave the scandoubler OFF; add Sharp Bilinear + scanlines + shadowmask in the OSD for the full CRT look.

ROMs are NOT included (copyright) — use your own MAME set. Sinistar/Playball are excluded (vertical/rotated → vis_warp bypassed; use the stock core).

Full guide: see the repo README.
