Hi porkupan, thanks for the heads up. I already use the external font file method with EPUB to read the book properly. The problem I try to solve is that Chinese titles does not show up correctly in the book list (i don't care about the menu) What I need to replace is the 003 file which handles displaying titles/authors/info etc.

Unfortunately, I busted my 650.

what I did is using win7(not recommanded), cygwin and cramfsck/mkcramfs,

-open up porkupan's new_opt.650.img, located the font files (inside opt/sony/font, or something like that)
-replaced it using the font file I found from another person's chinese replacement for prs600 (found here, http://www.hi-pda.com/forum/viewthre...age%3D1&page=1)
-repack using mkcramfs
-generate md5, rename new cramfs as new_opt.650.img to replace porkupan's image, modify the md5 file and replace the value
-flash
- device erbooted once (screen flashed), rebooted second time (screen flashed) and now stuck there forever opening library.

I've already tried reset and hard reset with no resolution. sigh. It's stuck in the screen therefore computer couldn't recognize it so I can't even reflash it with porkupan's working image.

There could be so many things wrong with it
1. using windows to process cramfs (with linux file permission and case-sensitivity problem). I should have used my ubuntu machine
2. font file (could be too big for the space causing an overflow. I didn't check the original mount to see how much free space I have)
3. repack incorrectly. there are options in mkcramfs which I do not know or understand.
4. wrong use of the flasher? perhaps something along that line.

Anyways, i love my new brick.
