• Added PWM support from PinMAME. PWM (pulse-width modulation) is used by some games to simulate additional gray tones on the DMD. This was previously ignored, but thanks to @vbousquet we’re now getting much smoother gradients and more accurate grayscale rendering. This does not apply to colorizations, which still receive the original frames (increasing the bit depth there would break them anyway).
• Updated Serum to the latest version, which introduces an optimized cROMc format that uses an order of magnitude fewer resources. The original cRZ format is still supported but will be internally converted to cROMc. As a result, new colorizations will be distributed in this new format.
• Fixed the GitHub CI, meaning every update pushed to the repository is now automatically built and available for testing.
