2019 marks the tenth anniversary of the creation of ULAplus. This collection
includes over 300 legal-to-distribute ZX Spectrum games, enhanced for ULAplus,
with a mixture of classics and more recent releases from Jonathan Cauldwell and
the Mojon Twins. It also includes demos and resources to help you create your
own ULAplus software.

Thanks to everyone who gave permission for the inclusion of their software.

BACKGROUND

ULAplus is the standard for enhanced colour on the ZX Spectrum, increasing the
total palette to 256 colours. It is available as a plug-in replacement ULA or
external HDMI interface for original hardware. It is also supported in clones
and emulation.

ULAplus was conceived as part of the ZX Spectrum SE project in 1999 on Usenet’s
comp.sys.sinclair. When Chris Smith reimplemented the ULA, having reverse
engineered it for his book "How to Create a Microcomputer", he realized there
was room to implement palette support. A small group of enthusiasts collaborated
on Google Wave to create the standard and ensure it was as simple, powerful and
compatible as possible.

ULAplus is a royalty-free open format. The official specification is released
under the Creative Commons Attribution-Share Alike License. ULAplus is a
trademark of Chloe Corporation. A license is required for commercial use of the
trademark, but not to implement the mode.

SPECEMU

To enable ULAplus in SpecEmu, press F8 and then select the Display tab.
