I tried to understand the japanese babel translation ... but it's really not easy this time. From what I understand Hikaru released the sourcecode of the latest version of Chihirox.

update: Shadow_Mx sent us a translation of what Hikaru said on his newspage:

Chihiro X Source Code Released
(Rakusai_1.00.rar)
(picture is a demo made from the SC)
After this he explains that the previous XDK-How To site works, but it has a problem. Then he explains how to compile Chihiro GBA. He has plans to release the source code for the other emulators.
