TOS/hard disc/floppy images are selectable in the OSD (F12).\nWith F11, you can toggle between normal and STe joystick ports.\n\n## Current issues/limitations:\n\n- No RAM cache for Mega STe (but the cache control selects turbo bus speed)\n- Only fake LMC1992\n- PAL clock only (32.084 MHz)\n- Since Jagpads have 21 buttons, not all are mapped to MiST controllers when using STe game ports\n- No STe paddle handling (but it has 0 software support)\n\n## Thanks to:\n\n- Till Harbaum for the MiST board, original MiST core, new IKBD code\n- Jorge Cwik for the FX68K CPU core, FX ST Blitter code and shifter decap\n- Christian Zietz for recovering the schematics of the GSTMCU\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgyurco%2Fmistery","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgyurco%2Fmistery","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgyurco%2Fmistery/lists"}
