Robotron-VIS v0.1 — vis_warp on Williams (6 games)
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)
RobotronVIS_20260528.rbf→/media/fat/_Arcade/cores/- the
(vis_warp).mrafiles →/media/fat/_Arcade/ - your own MAME ROM zips (robotron.zip, joust.zip, …) →
/media/fat/games/mame/ - 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).
