Binary problems running in IDE!

[Dark Hayabusa]

Add a few extra applications on my custom interface for Dreamshell which run smoothly in SD but when running in the IDE the screen goes black !?

Example: "os.execute (string.format ('exec -b f ide / DS / apps / DCPlaya / DCMC.bin' os.getenv ('PATH')));"

I'd also like to know if you can use a specific text in a file in the DS folder without having to specify it in all applications.
Such as the version of "Dreamshell 4.0.0 RC 2" on the back of the desk. (This session for user "Dark Hayabusa in my case" and in the future to change it to another user.

And finally you can include the clock as the original interface of the Dreamcast? Is there any command for this?
