"This is an interim release between some major changes to the video mode support, which may take a long time to complete. It also fixes a bug with CGRAM access timing, re-adds the Sufami Turbo load menu, and adds support for the ST-010 coprocessor, used by F1 Race of Champions.
To load Sufami Turbo cartridges, stbios.bin must be placed inside a folder named bios in the bsnes folder. There is not currently a warning if this file is missing.
