Rilasciato il nuovo firmware 8b beta per l’interfaccia Chameleon

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)

Rilasciato il nuovo firmware 7b beta per l’interfaccia Chameleon

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).

  • added native updater program (see manual) to update the fpga core without an usb connection.
  • make menu item active when pressing a hotkey, so it is selected when going back to the respective menu.
  • correctly mute/unmute second sid in menu freezer.
  • clockport- and rr-net- items in options menu are correctly disabled if either is not available.
  • if found, load and run update.prg from sd card (chameleon updater)
  • if “boot from sd card” is enabled, load boot.prg from sd card (regular c64 boot program)
  • improved navigation in one panel mode, cursor right enters subdir/image and cursor left goes one level up.
  • improved quickfind, just type a filename quickly to jump to it.
  • mount menu is skipped if there would only be one active item.
  • when returning to the menu from the sid player by pressing left/menu button it will go directly to the filebrowser.
  • added gfx viewer for various multi-color and hires formats.(see manual)
  • added wav player (see manual)
  • added filecopy (F5 in two panel mode, see manual)
  • set $030c-$030e to 0 before starting prgs, increases compatibility with certain packers.
  • .sid files which actually contain a basic program can now be run correctly.
  • re-read destination panel after copying image.

Rilasciato il nuovo firmware v6g beta per l’interfaccia Chameleon

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:

Differences from Beta-6f to Beta-6g:

  • Implemented bit-fade in SID when no waveform is selected.
  • Implemented bit-fade in SID when reading write-only registers.
  • Added bits to detect in menu when disk-images need update after write actions by the emulated drives.
  • Implemented “door” on emulated drive, when open drive will read dummy bytes.
  • Fixed CPU instruction timing bugs discovered when comparing emulated 6510 against real 6510.
  • CPU irq/nmi timing fixes.
  • Implemented bit-fade on I/O port of emulated 6510.
  • Fixed SID stereo mapping for D500 and D700.
  • Four timers added at addresses D0AA to D0AD for menu (it can’t use CIA timers when freezing).

Tengo a precisare che la cartuccia puo’ essere collegata ad un normale monitor VGA (LCD o CRT).

Changelog:

Differences from Beta-6c to Beta-6d:

  • Cartridge emulations.
  • Turbo speed increase: Eliminated one clock cycle from critical path.
  • Turbo speed increase: Writes to memory concurrent with next instruction fetch.
  • Turbo speed increase: MMU caches last used CPU slot.
