Introduction
This is a guide on how to make your own ]gameboots for you PSP. A gameboot is the little video thats about 2 seconds long that plays when you start a game. But beware this can result in your PSP becoming a brick because gameboots are flashed to the PSP's intenal drive called Flash0. In this guide I'll be using quite a number of different applications. Ok, with that out of the way we can start the guide.

[DYV] Downloading Your Video Off of Youtube 1.Find the video you want off of youtube
2.If you are using Firefox just use the Download Helper to download the .flv file. If you are using Internet Explorer open a new tab/browser.
3.Go to the site:
TechCrunch 4.Once you're there simply copy the URL from the youtube video and paste it into the "Enter YouTube URL" box and hit Get Video.
5.Save the file with the extension of .FLV
Firefox 
Internet Explorer 
[CYV] Converting Your Video Source 1.Install SUPER converter and run it or use any other converter that you know that can convert .FLVs to .AVIs.
2.For the users of SUPER the settings are..
Video Options Aspect - 16:9
Frame/Sec - 29.97
Options - Hi Quality/Top Quality (Takes a while to convert with Top Quality but has the best outcome),
Audio Options *Only do this if you want audio, if not hit disable
Sampling Frequency - 44100
Channels - 2
[img width=370 height=400]http://img160.imageshack.us/img160/9208/step2settingsih0.png[/img] 3.Now drag your .FLV video into the gray box at the bottom and make sure it's checked and then hit Encode.
4.When it's done go into the folder where you installed SUPER and look for the Output folder, that's where your video will be.
[VED] Video Editing 1.Install and run TMPGenc Xpress. Your also going to have to run the crack thats included.
*Note: You can also use your own video editing software but the maximum length is 72 frames long, frames not seconds.
2.For the TMPGenc users, hit the Set Source tab and drag your video into the box.
*Note: If you come across an error saying that the video cannot be loaded, only the audio part can, you need to hit New Project then add your video.
-Thanks to cold dog for pointing that out for me 3.Once it has loaded your video a popup should appear, make sure you set the Aspect Ratio to 16:9 or it wont be full screen on your PSP.
[img width=600 height=237]http://img235.imageshack.us/img235/4169/step3clipinfoea5.png[/img] 4.After that click on the Cut-Edit tab, now this is the hardest part. You want your video to be exactly 72 frames long, not seconds the gameboot itself wont even be 2 seconds long.
5.Now there are two VERY IMPORTANT rules here.
A - When you cut the video that is in front of the part you want, find the exact frame you want then
subtract two from it, this will give you that exact frame
B - When you cut the video that is after the part you want, find the exact frame again and
add 1, that'll cut off all the frames after that.
6.Now that you know the two rules, you can start cutting the video. Look for the two boxes that say Start Frame and End Frame. That is the boundaries of where you want to cut off. So if you wanted to cut off part of the beginning it would be 0 in the start frame and whatever frame you come up with using Rule A. For cutting the end you put what frame you came up with using Rule B and the very last frame of the video in the End Frame box.

8.Now click on Volume Change, then check Activate Volume Change. The default of TMPGenc is to reduce the audio to 95% of the original video, so all you have to do is set it to 100% again.
[img width=426 height=400]http://img88.imageshack.us/img88/3138/step3soundcorrectionnx4.png[/img] 9.After you do that, just hit OK at the bottom. Then hit Set Output and choose .AVI Output.

I do not take any responsibilities for any bricks./!\ 1.Go into recovery by turning on your PSP while holding the R Trigger.
2.Go to Advanced then Toggle USB (flash0)
*Note: Make sure you have a memory card in or your computer will not be able to open the flash drive
**Note: 3.71 M33-2 has problems accessing flash through recovery so you can also use the VSH Menu feature by pressing Select in the XMB. Then set the USB Device to Flash 0.
3.Open the flash drive through My Computer. Then go here..
X:/vsh/resource/ 4.Then just back up the original gameboot and just replace it with your new one. Make sure your new gameboot is named gameboot.pmf.
*Note: Any firmware above 3.80 will probably have the gameboot hidden. You could either make it visible again through folder options or you could just drag your new gameboot in replacing the old (if you just drag it in you'll be deleting the old one).
[END] Finished Gameboot - Download This is the gameboot that I made during this tutorial.
It's Rathalos from Monster Hunter flying towards you and then shoots flames at you.
Note: Make sure to change it to gameboot.pmf Rathalos Gameboot
