OK, for the video I would like to say it wasn't all that specific and there are some incorrect labeling, But that's what mistakes are for is to fix them and being that you asked for pointers in the video says I should give you some pointers on how your tutorial should be done. the tutorial placement was correct but the wording was a little indecent. Here let me help so you may improve.
Tip: After writing a tutorial go back and check for misspellings and miswordings. Make sure the users can understand your writing and check for correct punctuation and spacing.
Here's how your tutorial could look for the greater good of the users.
Elements you need:
-Custom Firmware (CFW) (Not optional)
-Nitepr/Other Nitepr Revisions/MODS. (Not Optional)
-Selected game. (PSP Games)
-txt file (Notepad)
-Game ID
LET’S BEGIN
STEP:
1.) Adding codes (Assuming you installed Nitepr plug your psp into computer and enter USB Mode via Settings tab on your PSP Menu. You can also insert your memory stick right into your computer depending if you have a universal memory stick slot for accessing memory storage devices.
2.) Now that we are connected enter the files accordingly (Drive#: seplugins/nitepr/ULUS-?????. If you do not have the game ID read Below [HOW TO].)
->In this case my Cheats will be stored in the txt file ULUS-10310 Where ULUS-10310 is my game ID.
3.) Now we have our Game ID and named our txt document after it, we can now Copy/paste Codes into our cheats database. You can find codes for this game here or on listed sites in the description on the main source of this video.
HOW TO: GAME ID:
*Nitepr has it's specific tools we are only looking for the game ID so in this case we will be accessing 1 tool and that is "Create NEW CHEAT". What this does is prints a plane code into your txt document (0x00000000 0x00000000) this will print the txt document with the game ID followed by the plane code you have created.
(NOTE: It only prints a plane code which has no function it's for adding a blank line for you to implement your own code for testing or quick usage.)
LETS BEGIN:
STEP:
1.) Assuming you have installed nitepr and are ready to add codes to it launch your selected game and wait for the text on the top left of the screen to display. Once it has Displayed hit home twice to enter enable it and now call the device menu with the following keys VOLUME - + Press both at the same time. Now follow the prompt to enter and now you are in the Nitepr cheat device menu.
2.) Click R button to jump to next tab Click it until you enter [PRX] now that you are on [PRX] tab go down to the option "Create NEW CHEAT" Or anything of those terms. Now it has created a Txt document on your memory stick and you can now add CODES!!!!!
Enjoy.
OK I hope this example of how it should look will help you in future tutorials.
Remember to be spacific so it's user readable
