In order to properly install it, you will need to install the system software, and then clear out the registry after booting. You can also utilize the registry patcher application to patch the 1.0.3 registry to have it downgrade to the older settings version.

While it can be installed over 1.0.3, the system will need a hard reset each time it is suspended. This is due to the power method being changed in 1.0.3 and thus its' IPL will break sleeping on older firmwares. This can be fixed by either replacing '''power.prx''' from 1.0.3 or using the correct IPL. The 1.0.0 IPL (kbooti.bin) leaked on the game '''NBA Street Showdown'''. The 0.9.0 IPL also works and can be found on a few UMD games: two of these are Ridge Racers and Shutokou Battle, located in the PRX folder as '''kbooti.bin'''.

To make it run on retail units, you will need to remove the [[iplloader]] (first 0x1000 bytes) and make the following change to main.bin:
To make it run on retail units, you will need to remove the pre-ipl (first 0x1000 bytes) and make the following changes to main.bin:


0x04000714 -> '''0x3224007F''' (masks some check used in the Baryon leaf like in newer IPLs)
0x04000714 -> '''0x3224007F''' (fix for retail units, something related to IdStorage)


Optional, for compatibility with TA-082/86 motherboards:
0x04000730 -> '''0x1000FF47''' (clockgen fix, only needed for TA-082/86 PSPs)


0x04000730 -> '''0x1000FF47''' (clockgen fix)
You can then use ipltool to reencrypt the IPL.
 
You can then use ipltool to reencrypt the IPL. Alternatively (not recommended) you can also patch IdStorage by changing byte 0x18 in leaf 4 (Baryon) from 0x94 -> 0x14. This will allow the IPL to boot without modifying it.
