RPGMaker stuff for games made in RPGMaker versions prior to MV can be extracted with Falo's extractor. I'm pretty sure

is a reliable link for it. As far as that goes, I forgot I can just attach the decrypter directly--it's attached.
To use: open the RAR, extract RPG Maker Decrypter.exe to the directory with the RGSS3A file, start the decrypter exe, select "file->open file" and choose the RGSS3A file. Then, select "tools->extract all" and your images will show up in an "extract" directory below where the exe was run from. In that directory will be a "graphics" directory, and from there usually CG images are in the "pictures" directory. You can delete the "extract"directory without harming the game function.
It's funny. This very site has a wiki with RPGMaker Decryption instructions, and they are wrong. The links are for Petschko's decrypter, which I don't think works with versions prior to MV. Either way, Falo's extractor works fine for this game.
Of course, what you are ripping are the raw images--if the dev is building up the CGs with layers of images, you might not be getting exactly what you are looking for.
