The actual file you click on to open up the Shimeji has the extention .exe The zip link you provided doesnt have the .exe file in it, which is why many people say it isn't working.
I'm not 100% sure on how shimeji's work so correct me if i'm wrong, but for yours to work you would have to download another shimeji, export the 46 image files to a folder, make another folder in the img folder of the other shimeji and paste in the image files to that folder. But even then you would have two or more shimejis per one zip file.
Ah, the link I provided is just to get the shimeji--Not the exe file. This shimeji is not one I made, I'm just providing the link for those who want Dave Strider running around on their screen.
Having more than one shimeji in the file wont affect it strangely, I have them in seperate folders all in the original "img" folder that you find. And thats a good way to organize them as when you open the exe you can still quite easily just select them as the file of course organizes everything. and not many people actually have complained about it not working, not as many people as there are people asking me for links to shimejis that a person took down, so I refuse to give the link of.
Oh; well; if you go here [link] and get the shimeji-ee file then put the image folder for the Dave inside the shimeji-ee's img folder, then you can open the .exe file using that and start it up. Yes, it comes with two default shimeji's but you can delete those if you don't want them.
Its okay, I had to look up a tutorial at first. XD; [link] Here's the site you can download shimeji-ee on, when you download that, if you want the dave to work you HAVE to follow these instructions. Put the dave in a folder called Dave(That'll make it easier), then put that folder into the folder called IMG that comes with the program (It'll have two default shimeji's in there), then you have to start up the program and you can use only Dave, BUT if the Dave doesn't work I'll send a different download of the same shimeji.
