+KeyCleaner v1.4 by Chilly Willy
+===============================
+
+To install, just copy the KeyCleaner folder in the archive to your memstick.
+If you run this with HEN or on the Slim PSP, copy to the GAME folder. If you
+use a custom firmware, copy to the GAME150 folder.
+
+To use, run like normal homebrew. The first screen tells you the motherboard
+and region to which the IdStorage is set. You then have three choices: exit
+by pressing the CIRCLE button, analyze the IdStorage keys by pressing the
+CROSS button, or dump the IdStorage keys by pressing the SQUARE button.
+
+The first time you dump the keys, it creates a folder called 'keys', then dumps
+the keys into it. If you choose to dump the keys again, the 'keys' folder will
+be renamed, and a new 'keys' folder created. You can keep dumping the keys until
+you have dumped them 10,000 times, or you run out of memory on the memstick.
+
+If you press the CROSS button, you will be taken to the Analyze Keys screen.
+You can choose to analyze the keys as if the motherboard were a TA-079/81,
+as if it were a TA-082/86, or as if it were a TA-085. I made this selectable
+in case the IdStorage keys identify the motherboard incorrectly. It will tell
+you which motherboard it thinks it is in the top line. If you aren't sure,
+press the SQUARE button to view a picture that shows how to tell which you
+have. It is a picture of the back of a PSP (mine) with the UMD door open. The
+red rectangle is the area of concern. If you have 'IC1003' printed upside down
+on the motherboard in that area, you have a TA-082/86. If not, you have a
+TA-079/81. Please note that all current Slim PSPs are TA-085. Press any key to
+return to the Analyze Keys screen. You can choose 'Analyze TA-079/81' on a
+TA-082/86, just don't choose to fix any keys it says are bad because it will
+fix them as if the PSP were a 79/81. If you DO fix them as a 79/81, you can
+select to analyze the keys as a TA-082/86 to fix them. The reverse is true
+if you have a TA-079/81. Please don't mess with the keys on a Slim at this
+time as only a few of the keys can be fixed with this version. Specifically,
+keys 4, 5, 6, 0x42, 0x46, and 0x47. If you mess up any other keys, you won't
+be able to fix them in KeyCleaner at this time.
+
+If you choose 'Analyze TA-082/86' (then main reason you probably got this),
+it will print a status of the keys associated with downgrading and tell you
+if it thinks there is a problem. If you see 'Congratulations! Your keys
+appear to be fine.', then your keys are fine. Note that 'fine' means key
+5 has been patched using my method. If key 5 is patched a different way,
+it'll tell you key 5 is bad and give you the option of fixing it. It isn't
+REALLY bad, I'm just encouraging people to use my method of patching.
+
+If the IdStorage isn't okay, with key 5 patched my way, it will check for
+common corruption from downgraders. It currently recognizes the original
+hard-down method, the original (2.71) soft-down method, and the NOOBZ (2.80
+and 3.03) soft-down method. If the IdStorage matches one of those downgrade
+methods, it then goes to the Fix Keys screen. You will be asked if you
+REALLY wish to attempt fixing the keys. If you tell it to do so, it then
+fixes all corrupted keys. This version of KeyCleaner can fix ALL the keys
+without any files, so you don't need any other files as in previous versions.
+If one of the common downgrader methods is not recognized, KeyCleaner then
+checks certain individual keys that are commonly bad for one reason or
+another. This version of KeyCleaner can fix keys 4, 5, 6, 0x42, 0x43, 0x46,
+and 0x47. If key 0x46 or 0x47 don't exist, it will create it, then fix it.
+Old TA-079 PSPs often are missing 0x46 and 0x47. That is fine - it is the
+way those PSPs were. Don't feel you have to fix those two keys.
+
+If the analysis shows all the keys to be fine, and key 5 patched with my
+method, it will ask if you wish to unpatch key 5. Do NOT do that unless
+you have the custom IPL or are running your TA-082/86 on official Sony
+firmware with HEN (homebrew enabler) or you WILL brick the PSP! Given
+Pandora has made changing the firmware easy, and bricks recoverable,
+KeyCleaner has changed to reflect this. It can unpatch key 5 as part of
+the visible main key handling so that people with the custom IPL or people
+wishing to run 3.30 or newer Sony firmware have an easy way to clean up
+their keys and unpatch key 5. If you aren't sure if your PSP will run
+with an unpatched key 5, DO NOT UNPATCH IT!!
+
+This version of KeyCleaner will load the background and text colors from
+the file "textcolors.bin". If the file is missing, it will default to the
+old color scheme - white text on a black background. The new colors in the
+textcolors.bin supplied are white text on a warm blue background. The way
+to change the colors is to load textcolors.bin into a hex editor and change
+it as follows:
+
+Byte 0: 00
+Byte 1: red intensity for background (00 to FF)
+Byte 2: green intensity for background (00 to FF)
+Byte 3: blue intensity for background (00 to FF)
+Byte 4: 00
+Byte 5: red intensity for text (00 to FF)
+Byte 6: green intensity for text (00 to FF)
+Byte 7: blue intensity for text (00 to FF)
+
+For example, the contents of the default textcolors.bin is:
+00 20 60 A0 00 FF FF FF

+================
+This program was made possible by the efforts of many people. I'd like to
+thank idstoragefix, codes02, Stapol, Mathieulh, harleyg, Jas0nuk, and Dark_AleX. If anyone
+else thinks they deserve some credit, let me know. :)
