Comic Book DS is a program making it possible to read your Comic Books on your Nintendo DS. It allows to display those .cbds files in a fast, pleasant and intuitive way.

It can be also used as a photo or image based documents viewer. Those books can either be downloaded in the Book web page, or created thanks to PictoDS or pycbds. Different themes are available.

This Nintendo DS program should be used with the PC program PictoDS to convert files.

User Guide

Copy the cbds directory in the root of your card. This cbds directory contains the theme directory (which can be changed) and the ComicBookDS.ini configuration file.

This ini file can be changed manually in order to modify some ComicBookDS settings (you can alternatively update and generate it with PictoDS).

Choose one of the 3 ComicBookDS files (ComicBookDS.nds,, ComicBookDS.ds.gba) according to your flash card and copy it anywhere in your card.If the program doesn't launch or reports that fat is not supported then you will have to DLDI patch it.

The .cbds files (the books generated with PictoDS or downloaded from must be placed in the cbds directory. However, you can create some sub-directories to organise them.
