ti has nothign to do with flash space it's the actuly RAM(random Acxess memorey)  flash is jsut that NAND FLASH MEM and whe the psp loas the xmb into the Ram the bigger background or bigger anything top menu and such it over loads the mem and cause it not to display right .....what wee need is a way to use a pagedisk file of some sort off the memorey stickthat woudl be sweet...

How would wee need to edit vshmain.prx, to allow it to show the high res bg that your PSP makes in Flash1,  (when you save a wallpaper) ?


Thanks for sharing this great find  :D

What do you mean ??
you don't have to edit vshmain.prx, just go to Settings > Theme Settings > Wallpaper > Use and the wallpaper will be shown in the XMB.

Please explain your question a little bit better.

[Howto change the path (manually):

1.) Take a decrypted vshmain.prx and open it in your HexEditor
2.) search for flash0:/vsh/resource/01-12.bmp
3.) replace it with flash1:/vsh/theme/01-12.bmp (fill the rest of the old path with 0x00)
4.) flash the new vshmain.prx and 01-12.bmp (decrypt the vshmain.prx to maximize compatibillity)
Done!

      a) recode your JPEGs with 'JPEG-Encoder' to reduce size and delete metadata
          (the filesize of the resulting JPEG must be less or equal to the value you have edited in your vshmain.prx)

No, no... I meant, in your first post (quoted above) you say the "filesize of the resulting JPEG must be less or equal to the value you have edited in your vshmain.prx".  

So, I figure the instructions you gave for hex editing would be specific to the size of the 01-12.bmp created by this JPEG Encoder.

To get to the point of what I'm trying to ask:

If I use this vshmain.prx hack, can I use PSP Filer to move/rename saved wallpaper from Flash1 to Flash0 (01-12.bmp), and show my full res bg, with out corrupting my icons?

I'll just try it and see... (I'll report back with my findings :))

The edited value in the vshmain.prx is the filesizesize in bytes of the picturefile from each month. This means everyone of the 12 pictures must have the same filesize as the value describes.
I'm sorry to tell you that you are not able to use your wallpaper as 01-12.bmp because its filesize is 0x36FA05=(391734-bytes) and the maximum size you can use for the backgrounds is 0xFF7F=(32767-bytes), but I'm working on bigger filesizes.

2-Plans to increase the RAM size for the XMB
(But I need help from experienced PSP hackers to realize them)

1.) Find the value wich contains the maximum RAM usage of the XMB and change it to something other.
2.) Change the '...prx' that it uses the RAM the wallpaper in flash1 use to show the highres backgrounds. This will size the max. value for the filesize up to 0x36FA05 (391734-bytes) (Maybe wee find the max. value for the wallpaper, then wee can increase the size more)

This is very difficult and much work, but the more people work on it the quicker an better result wee get.
