Will this brick my PSP? NO. I'll tell you straight forward, Cintro Mod is "flashless" so theres no flashing involved. SIMPLE, so dont come here saying that you did this and then your psp was out of control because you cant fool me. ^^
Things you need to know:
1. Cintros can be as LONG as you want, theres no limit in length. example: Can be 5min long if you wanted.
2. This only works on Custom Firmwares, as stated above.
3. Cintro files are ".PMF" hence, You can use your gameboots as Cintros. I tested it and its 100% fine.
4. You can have "cintros + customized coldboot" you are never giving up one or the other.
5. The cintro file MUST be named "intro.pmf" and it needs to be located INSIDE "PSP/SYSTEM/INTRO" folder or it wont work.
6. I created the Cintro (Intro.pmf) and its included in the INTRO folder, just for you to start using Cintros ^^. After you can delete it and use your own.
Files needed:
=======================================
1. Cintro Mod zip file with all files needed.

=======================================
Procedure:
1. Download the file "Cintro Mod" I uploaded myself. Go get it under my "File needed" section.
2. Right click the file and "Select" Extract to folder "Wherever the file is located/cintromod" You should get a folder called "Cintro Mod" Inside this folder you'll find "Root of memory stick" which will let you know the hierarchy of where the folders should be located.
3. Copy and paste the "BOOT" folder into your "GAME" or "GAME150" folder (depending on your kernel settings) just like any other homebrew.

4. Now go back to "PSP" and get into "System". And copy the folder "INTRO" in there.Your done with the flashless process ^_^.

5. Last step ^_^, Now get into Recovery Mode, then go into "Configuration" and enable the following:
=======================================
* - Autorun program at /PSP/GAME/BOOT/EBOOT.PBP (Currently enabled) < This is how it should look.
=======================================
** TIPS **
If you want to have ONLY your coldboot 'video' and you dont want to have the "Original Coldboot" or your "Customized Coldboot" to be displayed after the cintro. Disable the following under "Configuration" same place as autoboot.
=======================================
* - SKIP SCE Logo. If you disable this; only the Cintro video will play.
=======================================
6. Now go ahead and EXIT Recovery Mode, then SHUT down your PSP completely and turn it back on and behold the "Cintro" The Cintro was made by me (Saint Seiya) ^^ as you can tell its longer than 2.5 seconds. Which is the lame limit gameboots have.
Your done ^_^!
