image-to-msx-converter v1.0.0 released!

Converts images to MSX2 SCREEN 8 (RGB), and MSX2+ SCREEN 10 (YAE) and SCREEN 12 (YJK).

Never-seen-before superb quality (if I say so myself) thanks to a brute-force approach, and a new luminance-aware conversion technique.

Open Source cross platform: Linux, macOS and Windows.

Attached: SCREEN 8 and SCREEN 12 examples.

MSX2+ SCREEN 12 image conversion is hard. But I took yet another stab at it. Here are some previews.

Left a traditional approach. Right my new luminance-aware brute force method. These are the same resolution, and exactly the same number of bytes!

Actually, the tool supports interlace as well, and YAE (SCREEN 10) and RGB (SCREEN 8)!

Soon to be released as open source.

Just listed some new #RC2014/#RCBus modules on my Tindie store

First up - #HDMI for RC. Based on the Tang Nano 20K FPGA, emulate #V9958 with extra special graphics modes!

Can you believe these screenshots are taken from an MSX2+? That its Yamaha V9958 videochip was capable of *this* in 1988? But yes, I've improved the MSX2+ AI Image Converter even further! Better AI model! Better scaling! Installable for offline use!

Convert your own pictures to SCREEN 12 format using https://randysimons.codeberg.page/msx-screen12-ai-image-converter/

So, I trained a neural network ("AI") to optimize conversion of plain RGB images to YJK for SCREEN 12 of MSX2+ and TurboR. That conversion is notoriously hard, because of the quirks and limitations of the 1988's Yamaha V9958 Video Display Processor.

You can use the tool yourself at https://randysimons.codeberg.page/msx-screen12-ai-image-converter/

The entire process runs in your own browser. Including the creation of .dsk image or .zip. *Nothing* is shared!

Examples of the output running in an emulator are attached.
