The ROMs should be concatenated in the order:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>C1541<\/li><li>Kernal<\/li><li>Basic<\/li><li>Function LOW<\/li><li>Function HIGH<\/li><\/ul>\n\n\n\n<p>The function ROMs are optional &#8211; they provide the inbuilt software found in the Commodore Plus-4.  Without the core will be a C16 (albeit one equipped, optionally, with 64k of RAM.)<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Controls<\/h2>\n\n\n\n<p>The C16 keyboard is emulated via the PS\/2 keyboard, and the C64 keyboard is more-or-less mapped directly.  This means that the keys on the C64 will do what the equivalent key on a C16 keyboard in that location would do.  In other words, the keys&#8217; function won&#8217;t match what&#8217;s printed on the C64 keycaps!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other keys:<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Function<\/th><th>PS\/2 keyboard<\/th><th>C64 keyboard<\/th><th>CDTV controller<\/th><\/tr><\/thead><tbody><tr><td>Menu<\/td><td>F12<\/td><td><br><\/td><td>Power<\/td><\/tr><tr><td>Play\/Pause tape<\/td><td><\/td><td><\/td><td>Play\/Pause<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The tape play\/pause function can also be accessed via the menu.<\/p>\n\n\n\n<p>Hold the menu button for 1 second or longer to toggle the scandoubler on or off.<\/p>\n\n\n\n<p>Source code for this core can be found at https:\/\/github.com\/robinsonb5\/c16\/<\/p>\n\n\n\n<p>The core is based around a TED implementation by Istvan Hegedus, and includes components writted by Mark McDougall, Michel Stempin, Stephen A. Edwards, Gideon Zweijtzer, Daniel Wallner, MikeJ, ehenciak, DarFPGA, Alexey Melnikov, Till Harbaum, Gyorgy Szombathelyi and Nino-porcino.<\/p>\n\n\n\n<p>The Turbo Chameleon 64 port wraps the MiST core in a compatibility layer  (DeMiSTify, by Alastair M. Robinson), and makes very few material changes to the core itself.  It does, however, include the newer SID implementation from the MiSTer C64 core, by Alexey Melnikov, with the lookup tables&#8217; representation adjusted to be more space efficient by Alastair M. Robinson.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is a port of the MiST Commodore 16 \/ Plus 4 core to the Turbo Chameleon 64 cartridge.
