Now that you have downgraded you can use homebrew.
there are alot homebrews
to use homebrew you first must make it 1.5 ready (most homebrew are already 1.5 ready) .
i use sei tool(but there are some others to). I use this one because it can hide the corrupted icons from the screen.
once you have "patched'' your homebrew you can put it on your psp.
put both folders on X:PSP/GAME/
5.
Since 2.0 is hacked you are able to play some homebrew.not all homebrews will work because the psp is not using his kernal
read the instructions carefully before posting something on the forums.

the best iso loader at the moment is DAX ZISO Loader v0.62 This loader can run compressed iso wich means you can put more iso's on you memory stick..
this loader has got many emulation modes, these modes are needed for running the newest
--------------------------------------------------------------------------------------------------------------------------------
Off: this method is only good if you want to emulate the flash files ( this is the same as a firmware loader )
--------------------------------------------------------------------------------------------------------------------------------
System menu. if you use this method it will exit the emulator letting you to load the game through the system
menu or another loader like mphgameloader.This is one of the most compatible modes
--------------------------------------------------------------------------------------------------------------------------------
Direct load. It will directly load your iso. this is a method wich is not as good as the others and you will see that many new games wont load with this method
--------------------------------------------------------------------------------------------------------------------------------
Copy load. It will copy the game boot.bin file to ms0:/DAXZISO/DBOOT.BIN and it will
load-exec it.
--------------------------------------------------------------------------------------------------------------------------------
MPHGL Direct.
It seems to be the less compatible mode of all. It's more compatible to use the system menu one and execute mphgameloader, or the modes "MPHGL System", "MPHGL VSHExec" and "MPHGL LoadExec".
--------------------------------------------------------------------------------------------------------------------------------
UMDEmulator:
This mode requires the file ms0:/DAXZISO/UMDEMU.PBP, which is already included.
This mode will load the original umdemulator letting it to load isos in dax format.
The compatibility of different load modes inside UMDEMULATOR should be more or less the
same that those from DAXZISO, although it may have some differences.
---------------------------------------------------------------------------------------
MPHGL System.
This mode returns to the system menu: in that moment you can run
your emulated
execute the file "ms0:/DAXZISO/MPHGL.PBP" which will load your 2.XX game.
The required file "ms0:/DAXZISO/MPHGL.PBP" is already included.
The
exiting to the system menu and then running mphgl.
---------------------------------------------------------------------------------------
MPHGL VSHExec.
With this mode your psp will reboot and after that it will auomatically
run MPHGameLoader ("ms0:/DAXZISO/MPHGL.PBP").The compatibility of this mode is greater than "MPHGL Direct" and exactly the same than exiting to the system menu and then running mphgl.
---------------------------------------------------------------------------------------
Direct LoadExec.
This mode looks like "Direct Load", but instead of using the
sceKernelLoad/StartModule functions, it uses sceKernelLoadExec; because of that, the system
will have more free memory, and this makes it more compatible than "Direct Load" and almost
as compatible as "System Menu". The only problem is that it always will run the BOOT.BIN
file (even if that option is in off), because sceKernelLoadExec fails with EBOOT.BIN.
If you have one of those game that in umdemulator only worked with copy load, try this one,
it loads faster and there are chances that it work.
---------------------------------------------------------------------------------------
MPHGL LoadExec.
This mode is as compatible as "MPHGL System" and
MPHGL VSH Exec, but it loads faster. However it has a problem: it doesn't work depending
on the wlan switch position. In my psp, it works with the wlan position in on, but it may be
different on your psp, or even different from a game to another.
This is NOT a DAXZISO bug. I've tried to execute the mphgl eboot.pbp with other homebrews
programs that also use the sceKernelLoadExec function, and without iso emulation (original
umd), and the results where the same: depending on the wlan switch position it worked or not.
---------------------------------------------------------------------------------------
RUNUMD LoadExec.
This mode will run RUNUMD, and it will let you load isos with it.
Because of a special
compatibility issue with RUNUMD, the flash0 and flash1 emulation are broken in this mode.
This mode requires the runumd pbp (folder without %) to be in ms0:/DAXZISO/RUNUMD.PBP
This file is NOT included, you'll have to provide it.
---------------------------------------------------------------------------------------
RUNUMD System. This mode returns to the system menu. After that, you can run RUNUMD
with the disc icon of the firmware. You can also start runumd from the your memory stick if
you want.This mode also requires the file ms0:/DAXZISO/RUNUMD.PBP and it also has the flash
emulation broken.
Note: if you use one of the other "System Menu" modes and you start runumd, it will gives
you the
to those modes in order to keep compatibility with flash emulation.
---------------------------------------------------------------------------------------
RUNUMD Direct. This mode is like "RUNUMD LoadExec", but it doesn't reboot the firmware, so
it loads faster and it doesn't delete a background program from memory. The compatibility
should be less than "RUNUMD LoadExec", although it seems still to be very good.
