This will work on other custom firmware psp's butvyou will need to go in to the mapviwer folder and replace the .prx files with .prx's from that firmware. to install mapthis 0.5 on 3.52m33 psp's just download 352m33gps.rar open it and put the mapviewer folder inside the GAME folder and if you get an error Game Could Not Be Started just try and move the mapviewer fodler into the GAME150 folder. Good Luck!

settings for 3.52 m33 user's psp: Hide corrupt icons must be disabled( to disable turn off you psp then hold the right shoulder button and turn your psp on it will bring you into a special screen it it dosent then you dont have custom firmware so the GPS wont work anyway. When your in the special screen go to configurations and disable hide corrupt icons),

if
you want better reception with your PSP GPS there is a extension cable
you can buy so that the GPS device isnt attached to the psp. This gives
the GPS device a better signal becasue the static from the PSP isnt
going on the GPS

if your psp-290 GPS device is not working it might
be caused by your psp's motherboard's corrupt files this can be solved
by using keycleaner v1.1- To use, run like normal homebrew. jsut put
the keyclearner folder in side your psp/game folder or psp/game150
folder and run the program

The first screen shows a status of the
keys in the PSP IdStorage (in the flash). It tells you what type of PSP you
are on and what it thinks about the state of the keys. For example, if you
had run the original 2.71 downgrader on your TA-082, it will tell you the
PSP is an original soft-downed TA-082/86.

You can dump the current IdStorage keys by pressing the SQUARE button. The
first time you run it, it creates a folder called keys and 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 key, you will be taken to the Fix Keys screen. You
will be shown a summary of the status of the IdStorage keys, along with a
suggested action to take. If the keys don't need fixing, it will say so, and
your only choice of action is to return to the initial screen. Depending on
how you downgraded your PSP, you may have one or two choices to fix the keys.
One way requires a dump on the memstick of the keys from a stock PSP. You may
call the folder anything you wish as long as it is in the same folder as the
KeyCleaner EBOOT file. Choosing to fix the keys from files on the memstick
will step through each folder in the KeyCleaner folder, showing the status
and state of the keys in each folder. Press CIRCLE to skip to the next folder
on the memstick. Press CROSS to select the current folder as the source of the
files used to fix the keys.

Once you select a folder of files to use to fix the keys, you are given one
last chance to abort - press CIRCLE to exit and nothing on the PSP will be
changed. Press CROSS and the files needed to fix the keys will be written to
the PSP IdStorage. Be carefull about these keys! A bad key can brick your PSP.
That is why you are given every opportunity to exit without changing the keys.

Sometimes, you will be given the opportunity to fix the keys without using files
on the memstick. This option will always be selected via the SQUARE button, and
cannot FULLY fix the keys. After using this option, you will be told that all
the keys but one have been fixed. If at some time in the future, you get files
to fix those keys, KeyCleaner will allow you to do so.
