MiSTer Improvements, Genesis & SMS FPGA Core Updates

The MiSTer FPGA Multi-Console Project’s main core, and Sega Genesis and SMS cores have received several updates recently. Some highlights include: integer & ultra-sharp nearest neighbor scaling, the ability to load scaler coefficient files (for custom video profiles, for example), and improved scanlines. Changelogs.

Cores need to be updated individually to take advantage of the new scaling features. So far Sorgelig and Rysha have added them to: NES, TG16/PCE/SuperGrafx, Genesis & SMS

MiSTer Updates

– Load <core>/coeff.txt to scaler on supported cores.
– ini option for vertical integer scaling.
