Okay so the vast majority of comments and stuff I get are how to run my shimejis on Windows 8. I'm not sure about 8.1 because I didn't end up updating because it was going to break some of my apps, but this is what I've found.
You have to make sure that you have Java downloaded and installed. You can do that with this link, it's free.
It says something funky can happen if you're running Chrome, I'm running Chrome and haven't seen anything weird, so I'm not sure about that.
Alright, once you have the Java installed, then open the shimeji folder and click on the JAR file, NOT the EXE file. As I use the same base file for all my shimeji, this should work for all my files. They should fall as normal.
I tried to convert it to the English Shimeji file and it wouldn't work at all, but my original ones would, just in case you were wondering. Just remember the JAR file is now what you click, not the EXE file and you should be fine.
Also I know a lot of you have been asking if I'll be releasing anymore, and if I'll take requests. Frankly I'm super busy right now and don't really have the time for shimeji, just to do it for fun. I've been thinking about starting a patreon profile and for those that support me, doing special shimeji and other things on it. I can justify putting the time in that way, and that will give my patrons a say in what shimeji I make, and a vote about what I do next. It wouldn't just be shimejis either, I'd do all sorts of things just for that. I haven't decided if I'm going to do it or not yet, we'll see what happens.
Anyway I hope this helps all of you!
