I just found a neat site with software for handhelds. I found some for my sh4 processor, and I see others for Wince 2.0 and even saw one for the Sigmarion 3.
The programs I downloaded were in Japanese. I liked one very much so I went looking for the author's site and found he had there an English version. That was Pocket Editor.
For me, it is difficult to find sh4 software - 1/2 of the sites I find the software are Japanese. And no, I don't read Japanese.
