I wish Perfect Viewer was available on the default Kobo OS ereaders. The Aura HD uses a modified ARM A8 CPU so technically speaking, the app should work. But the author hasn't done any updates in some time, so I guess the projects dead. Only APK files exist for it from what I could find.
Anyhoo, for my manga reading, I convert my files to CBR format. Some strange reason CBZ just doesn't work for me, even though it's just a zip extension, hmmm. Three tools I use to load up manga onto my device.
First, if the original image files aren't properly named and/or use a weird format, I use an program called
"Bulk Rename Utility" (
http://www.bulkrenameutility.co.uk/Main_Intro.php) to quickly rename into a 001.jpg/png/etc... format.
Once all the images are renamed, I rar it up with
Winrar.
Then I use an app called
"AnalogX Extension Changer" (
http://www.softpedia.com/get/System/...-Changer.shtml) to change the extension from .rar to .cbr. This one I like as it has a drag and drop feature.
I've been debating on loading Android for Perfect Viewer onto my Aura HD but this seems to work well, albeit time consuming.
