ImageMagick 6605
Using a test file 600.png www.lipowiec.org\im\600.png
1) convert 600.png 600.psb can not be opened by CS4 Photoshop
2) I compared the headers for files PSD and PSB created by CS4PS and IM6605
there appeared a difference in the Number of Channels field
CS4PS had value 1
IM6605 had a value of 3
3) I then created used IM6605 to create PNG compress none to create another PNG
then looked at headers CS4PS and IM6605 create when making PSD and PSB from this new PNG
In header Number of Channels field
CS4PS had value 4
IM6605 still has a value of 3
NOTE even though value differ between CS4 created and IM6605 both PSDs can be opened in CS4Photoshop.
4) What would you like me to look at to help determine areas that need to be addressed?
5) if ((psd_info.version == 1) && ((psd_info.rows > 300000) || in psd.c should have info.version == 2
some info below note sure if it will help
