As of the “2021/06/06” build, YY-CHR.NET has support for three planar formats:
* “1BPP Planar” as “1BPP 8×8”
* “2BPP Planar” as “2BPP GB”
* “4BPP Planar” as “4BPP SMS/GG/WSC”

This release adds support for five unsupported planar formats in the form of plugins: 3BPP, 5BPP, 6BPP, 7BPP and 8BPP Planar.

Notably, the 3BPP Planar format is used in some SEGA Master System / Game Gear games to store the player’s graphics, like:
* Sonic the Hedgehog
* Alex Kidd in Miracle World
* James Bond 007: The Duel

Source code is provided along with the compiled .dll plugin files. Instructions are also provided in the “READ ME” file if you wish to compile the code yourself.
