v 0.3 (new PCB)

• same firmware as in v0.3 beta 14
• new PCB with potentiometers for R G B VGA channel, through-hole

NOTE: Older PCB versions will still work with the new firmware version.

V 0.3 beta 14 (bug fixes)

This release includes:

• Some code tweaking to remove artifacts
• Sadly I had to shrink the MCEBlaster no-signal logo because of limited available memory
• 2 more sample offsets for CGA to improve sampling resolution
• A UI fix (med-push of Auto-Adjust)

Many thanks to @Bs0Dd and to @yyartsworld for testing and bug reporting !

V 0.3 beta 13 (add profiles)

This release adds profiles. This is helpful when you swap video cards and want to reuse the profile dialed in earlier for that specific video card. Profiles are accessed by long-pressing the auto-adjust button.

Warnings:

• This release removes the continuously auto-adjusting mode.
• This release will erase your settings

Many thanks to @Bs0Dd for requesting the feature and to @yyartsworld for testing and bug reporting :)

V 0.3 beta 12

• Fixes some noisy artifacts
• Increases sampling offset range for CGA and MDA to 8

Special thanks to @Bs0Dd for helping with testing and bug reporting!

V 0.3 beta 11 (Fix EGA 640x350 clipping)

This should finally fix the horizontal clipping in EGA 640x350.

Many thanks to @Bs0Dd for the detailed bug reporting!

V 0.3 beta 10 (Fix sampling offset bugs and fix clipping in EGA 640x350)

Bug fixes:

• Fix the sampling offset bugs (including the CGA and MDA ones) introduced by beta 9. Many thanks to @Bs0Dd for the bug report and fix!
• The horizontal clipping in EGA 640x350 should now be fixed. We can now use higher sampling offset values up to 25.

Interface change:

• When in pixel clock mode long-pressing now changes the pixel clock by 1 KHz. This makes it easier to try different frequencies now that we have too many sampling offsets to choose from.

V0.3 beta 9 (Fixes EGA 640x350 horizontal clipping)

The main change of this release is that it should fix the EGA 640x350 horizontal clipping by increasing the buffer size for Pico 1 (equal to that of Pico 2).
It also increases the number of available offsets from 4 to 16, which should help fine-tune the image.

To allow for a larger horizontal buffer, the vertical buffer size was decreased by 2 lines, but I haven't noticed any vertical clipping so far, please report a bug if you encounter this issue.

A minor UI change is that the pixel clock menu now also accepts long-presses for fine-tuning the offset.

Many thanks to @yyartsworld and @Bs0Dd for reporting these issues and helping with testing!

v0.3 beta 8 (Bug fixes)

This release fixes various issues and implements a couple of features:

NOTE: This firmware will reset your saved settings. If for any reason it doesn't the MCEBlaster may freeze, and you may need to reset to defaults by pressing both buttons for a few seconds while powering on the device.

Bug fixes:

• Fix MDA mode that got broken by v0.3 beta 7
• Fix MDA pixel clipping by making the buffer even larger
• Fix mode switching bug that would prevent switching from EGA 640x200 to 640x350
• Fix VGA signal generator sync pixel calculation
• Increase the buffer size for Pico 2 (by adjusting XB), which can now better prevent image clipping at the right hand side border
• Fix Manual-TTL menu long-push bug

Features:

• Vertical centering of EGA 640x350
• A few character bitmap improvements

V 0.3 beta 7 (Fix colors in some monitors) **MDA is BUGGY**

This release fixes the issue reported in #26 where the image brightness or colors would be off in some monitors.

Many thanks to @Bs0Dd for reporting, investigating and finding the root cause of the issue!

WARNING: The change has regressed MDA, so please avoid using this version.

V 0.3 beta 6 (Pico 2)

This version includes a firmware image for the Pico 2 (thanks @vslinuxdotnet for the notes).
