Infantile Paralysiser's Image Viewer works by converting the pictures into a special format using the PC end of the application and viewing them in an iPhoto-like environment on DS.


Download and unzip file, it is necessary to covert your photos to build your picture library with the software provided in the file.

Prepare pictures:

Run img2ipk.exe, select your preferred language.

An ipk file will be created on your desktop, this contains your selected images.

Set up DS ImageViewer:

A range of NDS files will then be created. Copy the following files to the same folder on your homebrew.

The imgview10_.nds file with a name extension that matches your device.

For high-quality images, switch from customjpeg mode to ZLIB mode for the high-quality (file size will be large).

User guide

About cache memory:

Since v1.0 an efficient memory management is introduced and you can use dual screen mode without extended memory.

However, it is recommended to use the extended memory together because it becomes heavy (from around 1024x768 or more) for large images.

Compatible expansion memory is M3 for GBA, SC for GBA, EZ4 for GBA, memory expansion cartridge bundled with DS browser, EZ 3in1 Expansion Pack.

GBA M3/SC/EZ4 cannot be used when booted from a DS card. SC/EZ4 for GBA needs to configure setting in imgview.ini.

If the operation is unstable, there is a memory test tool on the 4th page of the slideshow option, so please check it.
