La cartuccia Chameleon Turbo 64 è estremamente facile da utilizzare dal momento che non serve aprire il proprio computer perche’ si collega alla porta di espansione del C64.

La cartuccia può funzionare anche come unità “stand-alone” questo perche’ al suo interno il cuore e’ un chip FPGA che emula quasi (ancora in beta) del tutto un Commodore 64, compreso il Floppy Drive e puo’ essere collegata ad un normale monitor VGA (LCD o CRT).

Changelog:

• New VGA controller with new modes and VIC-II sync.
• Tripple buffering mode added for properly displaying IFLI pictures.
• Scale-2x video scaling algorithm added.
• Scanline emulation added.
• In cartridge mode real CIAs registers and interrupts are used (allows use of a modem).
• In cartridge mode real VIC-II registers and interrupts are used (allows use of a lightpen).
• Fixed I/O assignments for FPGA (lower power use).
• Lowlevel SD-card functions now use multiple block reads if possible, which increases linear reading speed by about 40 to 50% (most noticeable on large files, such as REU images)
• BUGFIX: fixed error handling and timeouts of the IEC routines, which makes all related operations more robust.
• BUGFIX: added missing timeouts to SD-card functions.
• Joystick port 1 now also works for navigating the menus.
• BUGFIX: on some C64s pressing shift would result in phantom keypresses (F1/F2) under some conditions.
• NEW: various new VGA modes and other options for the new VGA controller (see manual)
• Improved loading speed of file inside T64 images.
• Improved keyboard handling to make the browser a bit snappier.
• BUGFIX: the size of the character ROM saved by the ROM saver was incorrect.
• BUGFIX: .wav player stops at the end of the file and does not continue playing garbage.
• BUGFIX: files bigger than 2k are displayed correctly by the .txt viewer.
• BUGFIX: when copying files out of a t64 image the resulting file was missing the last two bytes and/or the last block was missing completely.
• BUGFIX: filecopy from/to a IEC device did incorrectly abort after 1 block.
• BUGFIX: filecopy filename character set conversion was broken.
• BUGFIX: AR/RR ROM was not correctly disabled when autostarting programs from the filebrowser with AR/RR enabled as default cartridge.
• NEW: added DOS wedge command (see manual)
• NEW: added load and save commands (see manual)
