Making a game playable for others (rm2k3)

I know that I need to copy every used RTP file to my projects' maps + harmony.ddl + write that packageflag... into rpg_rt.ini, right?
BUT! Is there any utility program that searches those files? (I know there is one but it only works with rmk2k :S)

Another question:
Any chance to make the game running in window-mode when started. (dont say press F-whatever or alt+enter after started...)

First question: Not to my knowledge. But then again, I've always relied on Harmony/FullPackageFlag to make my games playable. Wait and see if someone has a better answer.

Second question: Just to the right of Test Play, there's a toggle button for fullscreen and window mode. But yeah, f4 works too.

he probably meant a script that when you opnen the game, it automaticly opens full screen. no need to click ALT+ENTER , or F4...

@DarkGamer: This is for rm2k3
