Finally! Someone got around to programming a comic book reader for the PSP that reads cbzs and cbrs directly from the memory stick. It's a little slow, as would be expected from a program that resizes such large images on such a slow processor, but fortunately, you can overclock to 333MHz from the program itself. It's got all the good features, such as zooming, two different resample algorithms (one faster but harder to read, one slower but easier to read), rotation, and the like.
Source code is included. It is (mostly) GPL. This software is written by me, and Kip helped with the graphics and ideas.
If you encounter a bug, please send a full bug report to the email address listed in the readme or post it here. More details are inside the readme. This program is still in beta, so it might be buggy.
Put comics in MS_ROOT/comics. I hope you know how to install the program yourself. If not, read the readme. You'll need it.
The controls should be rather intuitive. If not, read the readme for more details on the controls.
Feel free to email me or post feature requests!
<edit>Also, please post which firmware you're on so I can confirm that this works on different firmwares</edit>
<edit2>This version is old! New version here: [RELEASE] PSPComic v0.9.6</edit>
