RetroAchievements support
 

It would be great if WinUAE supported this: https://retroachievements.org/

There is information about adding support at https://github.com/RetroAchievements...a-new-emulator

It is very straightforward and I have done it already for my own emulator (WinArcadia). It is intended for emulators that have menu bars, which WinUAE does not, but the RA team are quite friendly and I'm sure they could adapt their system to accommodate the WinUAE GUI.

Doesn't this have the usual problem: Amiga programs can get loaded in different addresses depending on config etc.

It'd probably make more sense for WHDLoad to support RetroAchievements than for WinUAE to do so.
