Nestopia UE 1.99.0 is released. Nestopia JG 2.0.0 is also released! This is a big release because it marks the first time there is a
single cross-platform build for all of the major operating systems. That release is based on a frontend called QTea (Quality
Tea Frontend), which is a Qt6 rewrite of my FLTK frontend, now extended to support many more emulator cores.
Originally, the plan was to only release a 2.0.0 with the new Qt6 GUI, but I decided to backport the core changes to the old
Windows-only port for people who still use old versions of Windows or are just attached to what they're used to.
I am not yet sure if this will be the last release of the legacy Windows version or not.
To summarize: Nestopia UE 1.99.0 is the old Windows build. Nestopia JG 2.0.0 is the new cross-platform build. In the future I will
be continuing to work with Jolly Good Emulation on development of QTea, which will translate into a better Nestopia GUI experience.
