Have you ever tried the PSP internet browser? Slow, limited and without a decent input method, is useless. Almost every times, opening an "average" website, the browser says "Insufficient memory to open the page". This also happens with the newer PSP-2000, besides it has a double amount of RAM. Moreover, the maximum cache memory is just 2mb! 2mb is enough only for a 1998-like internet browsing experience!
But now, thanks to the Netfront Internet Browser - HighMemoryMod patch, there will not be any memory problems! This loader loads the browser without the XMB, also enabling the extra unused ram on the PSP-2000!
Look what a speed boost!!

A noticeable boost!
Minimum requirements: a PSP-1000 or a PSP-2000 with a Custom Firmware, if your PSP has an Original Sony firmware, you must find a "Pandora" battery (soon i will publish an howto about this). The newer PSP-3000 are not supported because it is impossible to install a Custom Firmware on them. Also you must have a recent version of custom firmware. It has been confirmed that on version below 3.71 will not work. How to update the custom firmware.
How to install:
- Download the High Memory patch (source)
- Extract in x:\PSP\GAME\
- Load the program from the menu Games\Memory Stick
This program will not touch the system files, it just makes temporary changes in the RAM, use it without fear

UPDATE: The P86 team has released a new version! (Nicer loading screen, and an exit menu)
