• Can run homebrew using 3.02 kernel
• UMD Video region free
• PSP kernel region selector
• O/X button selector

3.03

PSN titles support expanded

Added:

• Support for taking photos and videos using the camera

3.03 OE

Released by Dark AleX

3.03 OE-A

• Change from firmware 3.02 to 3.03
• Added support for compression in psx isos (look at popstation documentation for more details)
• Added support for decrypted document.dat (psx games manual) (look at docmaker documentation for more details)
• Fixed a bug regarding free region: a stupid bug caused it not to work at all. Now it should work, although it has not been tested due to lack of umd's of different regions between the testers and me
• Some generic bug fixes in the code
• Redded the sdk

3.03 OE-A’

• Added cpu clock selection for umd/iso games. (not for vsh yet)
• Fixed various bugs regarding the recovery menu, one of them made "rare text" appear when entering in plugins if pops plugins existed, the other one caused a crash when pressing triangle.
• Fixed a small part of code in umd emulation that was not multithread safe.

3.03 OE-B

• Patched the firmware to allow decrypted mp4-AVC videos to play at 480x272 resolution.
• pic0.png was not shown in psp isos. Fixed.
• The speed functions were not dummied after setting the speed. This could cause the few games that set the cpu speed not to run at the selected speed in the recovery menu.
• Changed the structure of the program to have more free ram in game mode.
• sysmemp.prx removed, systemctrl.prx splitted into systemctrl.prx and vshctrl.prx
• Docmaker also now allows for 1000 png (images) to be used rather than the previous 100

3.03 OE-C

• AVC videos bitrate limit patched. The firmware limited the bitrate of avc videos to only 768 Kbps. OE now forces the limit to be 16384 Kbps. (Note: this doesn't mean than the psp can handle such a high bitrate, this means than they won't show error. I don't know which is the real maximum bitrate than the psp can handle at full speed)
• Speed of OE boot is now ~3 seconds faster than previous versions. (without plugins)
• CPU speed of XMB can now be changed.
• Wifi can now work at 333 Mhz!
• Added access to flash 0 and 1 via usb in the recovery menu, based on the great idea of USBSSS by Booster. Note that writing is enabled, so this is intended only for advanced users that know what they are doing in each moment.(It is not a great idea to change anything from the kd folder). Because of this addition, the rest of flashing options were removed.
• PSP isos can now be deleted as any normal memstick games. (also the size of the iso now shows fine when you press triangle->information).
• When formatting memory stick, GAME150, GAME303 and ISO directories will be automatically created!
• Changes in internal HEN core:
• If a EBOOT.PBP with a plain DATA.PSP had a data.psar, modulemgr took as size of the executable the size of data.psp+data.psar. Fixed. (this fix enables psx games to have plain data.psp without causing a memory error).
• Added a couple of patches found by Tyranid. One allows syscalls instructions to be used in kernel mode without causing a crash. The other allows sceKernelQueryModuleInfo to work with sceInit and previous modules.

3.10

Added:

• Dynamic normalizer
• Conserve memory option

• Tyranid's patch (added in 3.03 OE-C) consequences was not explained very well in the changelog of 3.03 OE-C:
• For programmers: it allows kernel modules to have user imports, making kernel programming in 3.03/3.10 less strict.
• For users: plugins and applications that worked in 2.71 SE, but not in OE, *may* now work in 3.03OE-C and 3.10 OE-A.
