Hi. Tiny Core is so configurable, it is unlikely someone's remaster would provide everything you want out-of-the-box. Tiny Core is the easiest distribution ever for quick copy/paste backups, so once you get your system running again just backup mydata and /optional or copy the entire contents of your pendrive onto a hard drive.
Tiny Core v4 is still popular and the repositories are available. Shouldn't take too long to get back to a decent system. I know Tiny Core 6 has a getFlash10 extension, it's probably also in v4 repositories. Or if using Firefox, just manually install the libflashplayer.so version you want into /plugins. Sorry can't help with Python. All customized personal extensions should regularly be backed up, even just a quick cloud/email attachment so they are never lost.
