d64 floppy.jpg Chameleon Beta 9d Firmware

What's new since last beta:

FPGA Core:

----------

 - Fixed DE00 disable bit (bit 2) for RetroReplay emulation.

- Fixed RetroReplay "REU compatibility" logic.

- Fixed PS/2 Pause key decoding. No longer triggers a ctrl key press.

- Fixed Comal-80 emulation (bits 5, 6 and 7 of banking register)

- Fixed Super-games emulation (bit 3 in DF00 to disable banking register)

- Fixed REU so it can write into color RAM correctly (REU emulation)

- Fixed REU buffer swap operation (REU emulation)

- Fixed REU register contents after failed verify operation (REU emulation)

- Added support for extra fire buttons on docking station

- Added support for disk write-protect (drive emulation)

- Improved emulation of the drive stepper motor (drive emulation)

- Various VIA emulation fixes (drive emulation)

 

Menu System:

------------

 Menu System:

  - BUGFIX: the I/O reset required by various features did clear the CIAs

            serial shift registers in a way that spurious interrupts could

            be generated, which caused some programs to crash when starting

            them from the file browser.

 

Filebrowser:

  - BUGFIX: the sidplayer was using incorrect timer values for playing tunes

            with NTSC timing on a PAL C64, or the other way around.

  - BUGFIX: the sidplayer did not correctly mute the second SID when re-entering

            the file browser

  - NEW: short press on right (reset) button will send an IEC reset to the

         emulated drives.

  - NEW: when F7 is used to blank the screen while playing a SID tune, the

         background color will be set to black and the rasterbars removed to

         reduce noise.

Options:

  - NEW: Drives can be write protected

 

Monitor:

  - BUGFIX: the "arrow left" character could not be entered in the monitor

  - NEW: the color ram can be shown/edited using the IO command

 

Freezer:

  - BUGFIX: the CPUs of the emulated disk drives are stopped by the freezer and

            only released when actually needed by the menu system.

  - BUGFIX: also copy TOD registers of CIA2 in the right order :)

What's new since last beta:

FPGA Core:

----------

- Fixed disabling of RetroReplay cartridge emulation when set as default cart.

- Fixed supersnapshot cartridge emulation (supporting the disable bit).

- Fixed color RAM access in turbo mode.

- Fixed REU eliminating transfer errors caused by badlines (and sprite DMA).

- Added separate color palettes for PAL and NTSC modes.

 

Menu System:

------------

Bootloader:

  - NEW: added magic key '4' to start in 640x480@60Hz VGA mode

  - NEW: work around sprite-address counter initialization bug of the 6569 by

         enabling the sprites during boot

Filebrowser:

  - BUGFIX: when a disk image is changed/mounted and the drive CPU is running,

            also trigger the respective on/off transitions at the write protect

            sensor. when using the chameleon as standalone external drive this

            allows to change the disk inside the browser without having to go

            to basic.

  - BUGFIX: when using autostart send an "I" command after IEC reset, this

            improves compatibility with some loaders that rely on the drive

            being initialized.

  - BUGFIX: disable super snapshot v5 before autorun

  - BUGFIX: disable mach5 before autorun

  - BUGFIX: disable warpspeed before autorun

  - NEW: prepared d64 and g64 mounter for variable track length support

Freezer:

  - BUGFIX: $dd00 was not properly saved when freezing

Tools:

------

  - the tools were moved into a public repository

  - updated windows .exe files with updated libusb

 Chaco:

  - tick 'flash additional roms' automatically when choosing slot 0

  - added warning when slot 0 is flashed and no ROM file is used

d64 floppy.jpg Chameleon Beta 9f Firmware
These are the changes since the last beta release. For the detailed history
please take a look at the releasenotes in the "Documentation" directory.

FPGA Core:
----------

- Added remote reset feature
- Fixed Pagefox Cartridge mapping
- Fixed KCS Power Cartridge (BLOAD)
- Fixed drive write protection, the disk could still be written to even if the 
  sensor was 'open'
- Added variable track length support to drive emulation
- Fixed interrupt flag for VIA timer 1 in single shot mode.
- Fixed glitch when writing to colorram from REU when BA signal goes low.


Menu System:
------------

  - BUGFIX: use $01 instead of $ff for the CRC7 field in SD commands - although
            the specs say the CRC bits are "dont care" when CRCs are disabled,
            this seems to be required for some cards.

Bootloader:
  - BUGFIX: better RAM init pattern

Freezer:
  - BUGFIX: better detection and restoring of active CIA interrupts

Filebrowser:
  - BUGFIX: added handling for additional DOS errors (1581, CMD)
  - NEW: support for changing/creating/deleting directories on IEC devices,
         tested against sd2iec.


Tools:
------

  - updated tools to the latest binaries from the public repository.

d64 floppy.jpg Chameleon Beta 9g Firmware

New since last beta:

- Added support for "Nordic Power" mode in Retro Replay cartridge emulation

- fixed Retro Replay RAM writethrough (now passes "AR+Co Acid Test")

- SID does no more produce output for 6x and 7x waveforms when 6581 is selected (fixes certain SID type detections)

- SID: fixed readback of floating bus value (fixes busvalue.prg)

- fixed writing to RAM locations 0/1 (fixes ram0001 test)

- SID: added noise writeback (fixes the "pico" demo)

- Drive emulation now works per bit (instead of byte) on GCR data - Added "weak bit" emulation to drive emulation

- changed PAL colors to a new, more saturated, palette based on peptos new "colodore" research

- SID: much better approximation for mixed waveforms 3x and 7x

These are the changes since the last beta release. For the detailed history
please take a look at the releasenotes in the "Documentation" directory.

Tools:
------

 flasher:
  - renamed the binary from "update.exe" to "flasher.exe". the former would
    trigger pointless UAC warnings in win7 and up.
  - detect chameleon v2, and selects the v2 core via filename pattern
  - restart core 0 after abort

 Chaco:
  - disable "start bootloader" button when no chameleon is connected

FPGA Core:
----------

- Added support for the 1MB homebrew variant of the "Magic Desk" cartridge
- Added support for the optional EPROM on the COMAL80 cartridge
- Added support for the 256kB "FC3+" FC3 images
- Fixed RAM mapping in "ultimax" mode
- Fixed mapping of the Character ROM in VIC cycles
- Fixed reading of write-only cartridge registers
- Various CIA fixes, allows switching between "new" and "old" CIA now

Menu System:
------------

Filebrowser:
  - BUGFIX: the easyflash related EAPI function to erase a sector did write to
            I/O instead of cartridge memory, which would result in broken audio
  - BUGFIX: when mounting a d64 or g64 image on the second drive, the wrong
            image would be marked active and diskchange was always triggered on
            the first emulated drive.
  - BUGFIX: set $ba (current drive id) to the device id of the d64 image when
            starting a prg file from inside a mounted d64 image.
  - BUGFIX: in the "file action" (SPACE) menu do not show the "load" option when
            the menu is invoked on .geo or .reu files, and the respective
            expansion is not enabled
  - BUGFIX: show a message when trying to load a georam or reu file and georam
            or reu is not enabled, or the file is too large for the configured
            size

Settings:
  - moved VIC and CIA settings into "Emulation settings" Menu
  - added CIA type selection
