Beta48 test release

This is a release candidate for the next stable version
Add Intellivision_60Hz profile
(50Hz should also work but will require a completely different way of connecting and a different profile)
Add support to use composite blanking instead of composite sync (used by Intellivision)

Beta47 test release

Beta47 test release
This is a release candidate for the next stable version
Fix regression that caused a hangup on auto reboot to change scaling

Beta46 test release

Beta46 test release
This is a release candidate for the next stable version
Fix bug that stopped resolutions of 1024x768 and lower from working at 16bpp
Add delays before reboot and changing clocks
Improve disable_overclock feature
Update firmware

Beta45 test release

Beta45 test release
This version is a release candidate for the next stable release which will be the first one to support the Pi zero 2W

Changes:
Finalise Pi4 support
Fix various regressions causing minor glitches on Pi zero
Add Enterprise profile (untested)

This version should work on all Pi versions except the original Model A & B with the 26 pin GPIO header although only the Pi zero / zeroW and zero 2W are tested regularly.
In order to provide full functionality the old Pi 1 and Pi2 models have to be overclocked so if your particular board can't handle that you can switch the overclocking off by editing config.txt and changing to 'auto_overclock=0' but some features may not work after that.

Beta44 test release

Beta44 test release

Changes:
Slightly improved mode7 calibration
Add Swedish computer ABC80, NEC PC-98 and Epson clones profiles
Fix garbage on right hand side of screen in teletext mode when using GPU capture
Merge support for Pi zero, zero2W, 1, 2 & 3 into one binary
Pi4 support now mostly working, only genlocking and screencaps not working yet.
Support old CPLDs in GPU capture mode

Beta43 test release

This is a major new release with full support for the Pi zero 2W (should also work on the Pi 2 and Pi 3 (all variants).

The capture side has been moved from the Arm processor to the GPU with a significant increase in performance which means that 12bpp support now works on the Pi zero 2W

Please test and report any issues

Beta42 test release

Add Pi zero 2W support:
NOTE: Currently 9bpp and 12bpp capture doesn't work with a Pi zero 2W. This is because reading the GPIOs is 25% slower than an original Pi Zero and there is insufficient time to capture the full 12bpp.
This means that the Amiga, Atari ST, NuLA and AppleIIGS profiles are hidden when a Pi zero 2W is used and a warning is shown on screen.
All other 1bpp, 3bpp and 6bpp profiles including Apple II/IIe/IIc still work on the Zero 2W

Ideas to work around this limitation on the Zero 2W are currently being investigated.

Also:
Add 9bpp and 1bpp support for simple mode
Fix interlace detection bug
Improve selection of optimal calibration in mode 7

Beta41 test release

Add FFOSD support for 9-12 bit capture into 8 bit frame buffer (Sam Coupe)
Improve Integer scaling for some non square pixel ratios.
Minor bug fixes and profile updates

Beta40 test release

Change Apple IIGS switching mode to remove manual override (You can select the old mode by changing the Autoswitch setting to "Sub + IIGS + Manual"

Improve screencap aspect ratios when using interpolated scaling.

Various profile updates

Beta39 test release

Beta39 test release
Fix some issues with Apple IIGS mode detection and image glitches
Update profiles
