I tried replacing icons in 16 bits NE files (*.exe and *.cpl) with VC++ 6 and it works fine as long as you use 256 colors icons. Plus it's nice and easy to do.

However, it only has option to add monochrome, 16 and 256 colors...
You can trick the program by importing an already existing 16bits icon but there is no way to add 32bits icons without breaking the file (it ends with faulty mixed 16bits/16 colors formats).
My problem is I'd like to mod sysdm.cpl but Borland Resource Workshop crashes when I open any version of it.
Any ideas?
Edit: yeah, I'm using RP Lite, that's why I'd like alphablended icons. An I'd rather mod the *.cpl rather than change the Control panel icons from registry.
