purify v03 is released. It can be used to import your entire game library into higan's library in one pass.

With purify, you now have three ways to use higan:

First, exactly like other emulators: choose Load->Import and select which game file or ZIP archive you wish to play. It will load any file type regardless of extension or presence of headers. You can keep using Load->Import to play the same games over and over, and it will keep your saves intact. Treat it as if it says File->Load. You can also associate your ROM files with higan, and load them directly.

Second, in personalized library mode: choose Load->Import to pull in the games you want to play into higan's library, and then use Load->System from then on to play the games you want to.

Third, in complete library mode: use purify and import every game in your collection. Afterward, use higan's Load->System exclusively.

It seems few people realize the first step is possible. Yes, higan will load any file or ZIP archive. Just like every other emulator. And you can use it like that and completely ignore game folders and libraries entirely if you want. I would greatly appreciate if others could help dispel the rampant misinformation around game folders showing up on every other forum about this. I can't keep up with it myself.

purify v03 Changelog:

This version will also update previous XML-based game folders to higan's BML-based game folders.
