Q: Which version of your creations should I download?

A: That will depend on which engine version you are using. As a general rule, old versions will work in newer engines, but newer versions won't work in older engines.

Essentially:
Using Ikemen GO - download any version.
Using Ikemen - download Mugen 1.0 or WinMugen versions.
Using Mugen 1.1 - download Mugen 1.0 or WinMugen versions.
Using Mugen 1.0 - download Mugen 1.0 or WinMugen versions.
Using WinMugen - download WinMugen versions.

NOTE: As Ikemen GO is actively in development, you should also account for which version of the engine you're using.
For instance if you're using Ikemen GO 0.98.2, you shouldn't download something for Ikemen GO 0.99.

Q: Which version of those creations is the latest one?

A: This site's download buttons always link to the latest version. For older versions you can browse the Mediafire folder.

Q: I'm new at this. Where can I find Mugen for download? What about Ikemen GO? Where can I download more characters and stages besides yours?

A: For character, stages and other downloads, you can start with the collections found at Mugen Free For All.
Ikemen GO can be found at its homepage.
Mugen has no official hosting, but it should be easy to google.

You can find answers to questions such as these over at The Mugen Fighters Guild Forum.
I also recommend that you join the MFG Discord and/or the Ikemen GO Discord, as they are a lot more active.

Q: Can I make patches for your characters?

A: Yes, sure. You can even modify them entirely if you want.

Q: Can I use something from your works?

A: Sure. You can use anything you want.
Check the readme in case I used someone else's work, in which case you should credit that person instead.
Also, my work is distributed for free, so I'd appreciate it if it's also used in free content.
