RetroTINK 4K – Lumacode Support Added

Got a Lumacode NES? You’re in luck. Mike Chi just dropped experimental firmware for the RetroTINK 4K that finally brings preliminary support for these quirky, high-resolution retro consoles. It’s an early build, so expect a few bugs, but if you want to output a crisp, HDMI-like 4K signal from your modified NES, this is your ticket.
The setup is straightforward, though it requires a bit of tinkering. You’ll need to update the firmware via the SD card and enable Lumacode in the Advanced Settings. The catch? You’ll likely need to manually tweak the ADC pre-gain to get the image to snap into place, similar to calibrating an OSSC. Also, keep in mind that only the NES preset has been tested so far.
Beyond the headline feature, there are some serious quality-of-life upgrades. The 4K Pro gets a completely rewritten Horizontal Blur engine that makes dithering look authentically CRT-like without the usual composite video artifacts. Plus, a new “Native Sampling” option improves generic inputs by oversampling horizontally, and hitting the AUX4 button now instantly resets your zoom/crop settings. It’s a powerful update for anyone serious about preserving retro visuals.
