RetroTINK 4K Gets a Secret Weapon for DVD & SNES Fixes đŸŽźđŸ“Œ

Mike Chi just dropped experimental RetroTINK 4K firmware v1.9.9.8—and it’s got some sneaky upgrades that’ll delight retro AV enthusiasts.

The standout new toy? You can now apply the RetroTINK’s legendary 3D comb filter to HDMI inputs. Why does that matter? Because many early DVDs—especially those digitized directly from VHS or LaserDisc composite masters—carry ghosting, dot crawl, and other analog artifacts. This filter can smooth those out on HDMI sources (like a DVD player), making them look significantly cleaner—especially when the source is “just digitized composite.”

💡 Bonus: A new high-pass filter (similar to the RT5X’s pre-emphasis) is now available for horizontal blur control. Emily Young tested it on a 2-Chip SNES and found that setting the HPF to 2.00 MHz (or 3.00 in high-res modes) drastically reduces smearing—no hardware mod required!

  • ✅ Works great on composite-captured DVDs
  • ✅ Cleans up 2-Chip SNES artifacts (pretty much as close to “clean” as you can get without modding)
  • ✅ Zero risk—experimental firmware is easy to swap back from

Just remember: it won’t undo MPEG compression artifacts or fix fundamentally poor transfers—but for moderate analog messes? It’s a free, one-click upgrade worth trying. đŸ§Ș
