Please add support for the Japanese NEC PC-98 image files.
Here's the documentation about this format:

If you need to make more PI files, you can use this converter for MS-DOS:

A huge collection of PIC/PI/MAG and some other Japanese image files can be found here:

Is there English doc or source code?
I found this source patch that adds support for many Japanese file formats to XV. The Pi format is amongst them.

Sorry, I' know any. Maybe the only way is to google translate the Japanese documents.
Since the original links at www.jisyo.com are now broken, I decided to directly attach the Pi file format documentation here.
That is quite complex! I would never figured it out from the Japanese doc or its Google translation. The XV patch looks good though.
NEC_PC98_PI_files.zip only contains 16-color pictures with explicit palettes.
Can you find 256-color pictures and pictures with default palettes? The link at the nfggames forum is now dead.
I didn't imagine it was so complicated, sorry!
Here they are. Some 256 color Pi files to help you with the testing.
Thank you!
