Jonathan fixed some bugs in his SDL version of Fractint. This is a literal port of the DOS version, but runs directly under Windows. I briefly tested it under the latest Windows 10, and it ran like greased lightning compared to the DOS version running under DOSBox. Here's what Jonathan said about it:
I fixed the video resolution change crash and updated the files on fractint.net. There is still an issue when you use the mouse to create a zoom box while the image is still generating. For the most part, everything works. There is a list of issues in the New Features section of help.
Just unzip the directory SDL2-fractint-20.05alpha-2020-12-26 someplace on your Windows machine, browse to it with Explorer, and run fractint.exe https://fractint.net/ftp/experimental/SDL2-fractint-20.05alpha-2020-12-26.zi... Since the list is quiet these days, probably OK to post feedback, tips, and experiences here. Tim
