I love the .PRG and .PNG export ability. Great app.

Another PETSCII editor to be aware of is David Murray's. (i.e. "The 8-Bit Guy" on YouTube) It's a modern native editor, running on the C64 and PET.[1] Apparently there's also a version for his in-the-works Commander X16 "dream computer".[2]

I'm also aware of this online editor. http://petscii.krissz.hu/

I love this. Absolutely fantastic, especially with all of the keyboard controls. I've not been able to get the PNG import tool to work at all, but everything else seems really solid.

Thanks! PNG import is mainly intended for pulling PETSCII content into Petmate from running .prg files in VICE. The pixel data and image dimensions need to match exactly for the import to succeed. I try to explain it in the docs but the feature just kinda doesn’t do what most people expect it to.

Ah, OK I see. Thanks for explaining that.

been using this. works pretty well. i love reordering the palettte into several configs. i also like the 'r' key to rotate tiles.

FWIW the macOS binary hasn't been notarized.

Petmate author here. Doesn’t notarization require an Apple Developer ID? Out of principle, I don’t want to pay Apple 100 USD a year just to build my free app.
