itch.io

Hay una versión en español en la página de indie horror rpg games, no la llegué a probar, pero igual creo que funciona, dejo el enlace: https://indiehorrorrpg.blogspot.com/2014/04/mogeko-castle.html

You will need to download it the rpg maker VX ace RTP that you can find in the oficial rpg maker web site, in the tab of downloads. Then, you will be able to install it properly form the vgperson website that you can find at the bottom of the funamusea web page for mogeko castle.

Ok, I have the solution (if you want to install the japanese version, the one that is in itch(this one)). I figure it out that if you install the game from the itch io app (NOT from the web page/downloaded webpage) it will install it correctly, also, you don't need to install the japanese language package! Hope this help, and sorry that the last one(post) didn't worked, I didn't know.

(Edit 2: this doesn't work)Hi, it maybe very late, but better that never, I recently discovered that you need the windows Japanese package in order to the game to install right(you can find it in the language menu in your windows configuration menu, you only need the main one, not text to spech or spech to text). Edit: I almost forgot to say it, but this is because the songs name are mostly writen in Japanese, something that windows wilI not know how to write without the japanese language pack. I hope this may help.
