Morning, gang.
Here's a 'portable' of Pinta, based around the AppImage of v1.8 that bigpup found about a year ago. This is the last one that would work in most Pups; from 2.0 onwards, huge changes were made in the .NET requirements, along with the need for GTK-3. The upshot of these is that to run Pinta v2.0, you now need a very new Puppy.....only Fossapup64 or higher will now do.
I've given this my usual 'treatment'. You can run it from the 'LAUNCH' script, or you can add a Menu entry if preferred. Config files are all self-contained, sym-linked out at boot & deleted again at close.
You can find it here:- https://mega.nz/folder/SSoimZAI#DAmU0ok44kzf5At_TT2kcw
Best to move the unzipped portable outside the 'save'. Enjoy!
Mike.
