Great news for custom firmware fans, Dark_AleX has released version 3.03OE-B of his custom firmware for the PSP.

As expected, this release sees the PSP able to finally play full 480×272 resolution mp4-AVC videos, rather than the standard 320×240 size that the standard PSP firmware allows.

changes in OE:

- Patched the firmware to allow decrypted mp4-AVC videos to play at 480×272 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.

Note: due to the inclusion of pic0.png, the iso cache has changed slightly; as a consequence you
will notice a slowdown the first time you access game menu after this update, just as if you have
modified the iso folder.

Changes in docmaker:

- A flag that lets increase the limit of 100 png’s to 1000 was found. (this is the real maximum
number of images that support the emulator document.dat reader).
The document.dat’s created with this version, can have any number of images between 1 and 1000,
and they will work in whatever 3.03 OE version.

Instructions:

- Just copy the files/directories inside MS_ROOT to the root of your psp.

About AVC 480×272
Note that what is patched refers to mp4 avc (which are the ones with best quality).
Standard mp4 cannot play at resolutions higher than the multiplication of 320×240 because the
firmware is not really prepared for that.

To create a 480×272 avc, you can simply download 3gpconverter, choose the psp profile.
And then adding to transcoidng.ini something like this examples: (note: XX is a number not used by
other items).

Example 1: For a 1-pass 768 kbps bitrate:

[ItemXX]
Title=AVC 480×272 768 kbps 1-pass
TitleE=AVC 480×272 768 kbps 1-pass
Command0=”"< %AppPath%>\cores\ffmpeg” -y -i “< %InputFile%>” -title “< %Title%>” -timestamp “< %TimeStamp%>” -bitexact -vcodec h264 -coder 1 -bufsize 128 -g 250 -s 480×272 -r 29.97 -b 768 -acodec aac -ac 2 -ar 48000 -ab 64 -f psp “< %OutputPath%>MAQ< %RandomNumber5%>.MP4″”
Command1=”"< %AppPath%>\cores\ffmpeg” -y -i “< %InputFile%>” -f image2 -ss 5 -vframes 1 -s 160×120 -an “< %OutputPath%>MAQ< %RandomNumber5%>.THM”"

Example 2: For a 2-pass 512 kbps bitrate

[ItemXX]
Title=AVC 480×272 512 kbps 2-pass
TitleE=AVC 480×272 512 kbps 2-pass
Command0=”"< %AppPath%>\cores\ffmpeg” -y -i “< %InputFile%>” -title “< %Title%>” -timestamp “< %TimeStamp%>” -bitexact -vcodec h264 -coder 1 -bufsize 128 -g 250 -s 480×272 -r 29.97 -b 512 -passlogfile “< %OutputFile%>” -pass 1 -acodec aac -ac 2 -ar 48000 -ab 64 -f psp “< %OutputPath%>MAQ< %RandomNumber5%>.MP4″”
Command1=”"< %AppPath%>\cores\ffmpeg” -y -i “< %InputFile%>” -title “< %Title%>” -timestamp “< %TimeStamp%>” -bitexact -vcodec h264 -coder 1 -bufsize 128 -g 250 -s 480×272 -r 29.97 -b 512 -passlogfile “< %OutputFile%>” -pass 2 -acodec aac -ac 2 -ar 48000 -ab 64 -f psp “< %OutputPath%>MAQ< %RandomNumber5%>.MP4″”
Command2=”rm “< %OutputFile%>-0.log”"
Command3=”"< %AppPath%>\cores\ffmpeg” -y -i “< %InputFile%>” -f image2 -ss 5 -vframes 1 -s 160×120 -an “< %OutputPath%>MAQ< %RandomNumber5%>.THM”"

This update should only be run on PSP’s already running firmware 3.03OE-A or A2.
