USB drives with FAT32 file systems can now be read and written.
Currently only the first partition can be used. Drives must be inserted before the Pi is powered up.
Drives can be browsed using the keybaord or the buttons.
Currently FB (CBMFileBroswer) cannot be used to change drives.
All configuration and ROM files still need to be on the SD card.


Bug fixes


Fixed bug with SRQ line preventing the cassette from working.

V1.15

Bug fixes


Fixed bug - when using the device in browse mode some software was having issues with some file names. This has now been fixed. The best example was SidPlay64.

Keyboard changes.


Alt-Enter will now behave the same as the Insert key (for those using keybaords without an insert key).

V1.14

Bug fixes


Fixed bug - default mapping for the buttons was broken.

Buttons can now be remapped via the options.txt file. To do so set the following options;-
buttonEnter = A
buttonUp = B
buttonDown = C
buttonBack = D
buttonInsert = E

Where A, B, C, D and E are a number from 1 to 5.

For example, if you wanted button 5 to be Enter and button 1 to be Insert, put the following in options.txt;-
buttonEnter = 5
buttonInsert = 1


V1.13

1581 Emulation.


With 1581 emulation D81 images can be used.
Note: C128 burst mode is still in development.
Note: Only 512 byte physical sectors are supported.

You will need to add a 1581 ROM file to the root folder you SD card.
You will also need to add the following to the options.txt file
ROM1581 = YourROMName

Keyboard changes.


Alt-L to create autoswap.lst now includes selected drive rom.

Options changes.


OPTIONS.TXT numbers can now be decimal, hex.

Added options to remap the input push buttons.

V1.12

Browser.


Pressing "Insert" on a folder will select all images in the folder.

PopDir now hightlights the folder you were in.

ALT-L will create a .LST file form the currently selected images (named "autoswap*.lst").

Keyboard changes.


Pressing a-z/1-0 will jump to the next list entry starting with that letter.
You can now type more than one letter to narrow down the search.

BAM visualisation.


This has been changed to use retangles rather than characters.

Fixed MAJOR bug with 128 in 128 mode not booting.


If the 128 boots or resets after the Pi was booted it would try to use direct access disk commands read the boot sector of a disk whilst the Pi was in browse mode. This could lock up the 128 as it would wait forever for data to return.
This is now detected and fixed. So much so that there is now an option "AutoBootFB128" in the options.txt that if set, will allow a 128 to auto boot FB128 (if it is in the 1541 folder of the SD card).


V1.11

Fixed MAJOR bug with disks becomming CORRUPTED.

Due to incorrect emulation of CB2 line for VIA2 sometimes the emulator would incorrectly write to disk images just after a reset corrupting them. This has now been corrected.

Keyboard changes.


Pressing a-z/1-0 will jump to the next list entry starting with that letter.
The number keys no longer swap the ROM.
The function keys retain this feature so use them instead.
MUST use F1..F11 for rom and device ID changes.


Home and End keys move to 1st and last entry respectively.

LCtrl+LAlt+Delete can be use to re-boot the Raspberry Pi.

OLED will now display read only files in a unique way



Filenames will be post indexed with the character '<'.

Bug fixes


Fixed bug - changing ROM names now displays correctly.
Fixed bug - some directories werent show as directories.


V1.10

The selected ROM can now be changed via buttons.

Whilst in browse mode;-
If you have buttons hooked up to the Pi's GPIOs you can hold down button 1 and press one of the other four buttons to change the current ROM the emulator will use.
Button 2 will select your default ROM.
Button 3 will select the ROM configered by the ROM2 parameter in the options.txt file.
Button 4 will select the ROM configered by the ROM3 parameter in the options.txt file.
Button 5 will select the ROM configered by the ROM4 parameter in the options.txt file.

Compatibility fixes


myth_s1[system_3_1989](radwar)(pal) now works with type B configured hardware.

Auto Mount Image Options.


Alt A can be used to reslect the auto mount image set via "AutoMountImage" in the options.txt file.

The AutoMountImage can now also be a .LST file (if you would like multiple disk images to be auto loaded).

Write protection toggle.


Whilst in browse mode, Alt W can be used to toggle the write protection of a disk image.


OLED LCD SSD1306 128x32 is now supported



Add "LCDName = ssd1306_128x32" in the options.txt file.



V1.09

Device ID can now be changed via keys/buttons.

Whilst in browse mode;-
Keyboard buttons F8-F11 select device ID 8-11. (Note: amount of ROMS that can be swapped has been reduced to 7, ie keys 1-7)
If you have buttons hooked up to the Pi's GPIOs you can hold down button 5 (ie Insert) and press one of the other buttons. Button 1 = 8, 2 = 9, 3 = 10 and 4 = 11.

Compatibility fixes


California Games now works.

Alt N can be used to create a new D64 image.


The naming of the new images can be set via "AutoBaseName" in the options.txt file.


More OLED LCD Options



SH1106 support now works

Scanning of the I2C bus via "i2cScan" in the options.txt file.

Device IDs for the I2C LCDs on the specified I2C bus will be displayed on the Pi's screen.
You can then use this value for "i2cLcdAddress" in the options.txt file.


Bug fixes


Fixed bug - Scratch and New now refresh the browser view.
Fixed contrast setting for sh1106.


V1.08

Scrolling filenames.


Long filenames will now scroll horizontally to reveal the whole name.

More OLED LCD Options


Option to display a classic 1541 or 1541-II logo on boot up.

Bug fixes


Fixed bug with loading prg files in browse mode with similar filenames.

Escape will now exit an automounted image without re-autoloading it.

The directory preview of a mounted disk image will no longer display scratched filenames.

The demo "Industrial Breakdown" now works.

Inital track display of 00 has been fixed.

V1.07

Support for Aaction Replay, Epyx Fastloader and Final Cartridge cartridges loading FB64.


To do so place a disk image containing FB64 in the 1541 folder of the SD card then add the following line to the options.txt file;-
autoMountImage = fb.d64
Now whenever the emulated drive is reset the FB64 image will be automatically selected and mounted. You can use your fast loader cartridge of your choice to load it. Once loaded and running you can back out of the FB64 disk image and broswe the SD card as usual.

LCD Options


Contrast for the LCD screen can be adjusted.

Bug fixes


Fixed bug - when backing out of a disk image using FB64 the disk would not be written back if it was altered.

V1.06

Moved status bar to avoid overlap with 40 track BAM.
Fixed the emulation buttons debouncing issue.
Fixed bug with previous disk button now working as expected when you have a large amount of disks in the set.
When emulation mode is exited with disk images having been modified, messages will now be displayed on the screens to indicate progress and when it is safe to power down the Pi.
Piezo buzzer sound parameters can be modified in the options.txt file.
The I2C LCD screen can be flipped.

See the default Options.txt file for more information.


V1.05

The filenames of altered disk images are now displayed on screen when saving back to the SD card .
This will occur when emulation is exited.

V1.04

Fixed the insert/reset button from auto resetting the emulator.

V1.03

Supports I2C SSD1306 128x64 LCD screen.


Options.txt needs the line;-
LCDName = ssd1306_128x64
and depending upon how you want the keyboard's pgup and pgdown keys to work;-
keyboardBrowseLCDScreen = 1

Splits lines connect
SDA to GPIO 2 pin 3
SCL to GPIO 3 pin 5

Non-split lines
SDA to GPIO 0 pin 27
SCL to GPIO 1 pin 28

VCC to 3.3v and GND to GND.

Option to specify the file LOAD"*" will load.


In the Options.txt file add the line;-
starFileName = filename

Bug fixes.


Improved compatability with inverted split lines hardware configuration.
