You can still do that on your computer. Pic related, although it makes rikai turn sideways as well, which is kind of retarded.
What you can do is change those epub files to zip files (merely by changing the extension name), extract the files to their own folder and within that folder will be the following folders:>META-INF>OPS>mimetype
Within the OPS are the following files:>css>xhtml>package.opf>toc.ncx
Within the xhtml folder is the content: >0001.xhtml>nav.xhtml>title.xhtml
Open these up in your browser and it will display like pic related. You will have to change the xhtml extension to plain old html (change the name, same as before) in order for Rikaisama to work.
You can change the layout, etc. with the CSS file/s found in the css folder.
