Okey I see,

Well for any matter, this is also a kind of Setup/Start launcher, it also have progress bar, and you can also have your own loading screen image. Everything is customizble, such as text, icon, version info (on compiled .exe) etc. GRS are capable of compile a standalone .exe with all information stored in .exe file, so no need for external icons .ini files. Only loading images are external at this point.

Well, I think of letting your GS-Startup manager supporting .grs files.
