    Another update by hrimfaxi and coyotebean for PSP 6.30 Firmware and PRXDecrypter version 2.6a, which includes the new OFW 6.30 decryption method and keys.

    In 6.30 firmware Sony has add two new types of PRX to protect their executable. But we only spend one day to crack that. Currently there is only psp phat key, but it should be enough though.

    Key detail:
    /* 6.30 phat kernel s_code 0x43 type 3 */
    u8 key_4c9484f0[16] = {
    0x36, 0xB0, 0xDC, 0xFC, 0x59, 0x2A, 0x95, 0x1D,
    0x80, 0x2D, 0x80, 0x3F, 0xCD, 0x30, 0xA0, 0x1B,

    /* 6.30 phat kernel-2, s_code 0x5b type 3 */
    u8 key_457b80f0[16] = {
    0xd4, 0x35, 0x18, 0x02, 0x29, 0x68, 0xfb, 0xa0,
    0x6a, 0xa9, 0xa5, 0xed, 0x78, 0xfd, 0x2e, 0x9d

    /* used by vshmain.prx, s_code 0x5a, type 3 */
    u8 key_380280f0[16] = {
    0x97, 0x09, 0x12, 0xD3, 0xDB, 0x02, 0xBD, 0xD8,
    0xE7, 0x74, 0x51, 0xFE, 0xF0, 0xEA, 0x6C, 0x5C,

    DecryptPRX2 cannot handle these new "type 3" prx, so I imported PSPCipher kprx_decrypt function to make this psardumper to work. After decrypting, a new game key (0xd91680f0) is found in mesg_led_01.prx. It is likely we kicked sony's ass again.

    Credit: tpu dumped the IPL, and I found out what happened to the IPL decryptor.

    Note: this source has been already covered by GPLv3 becuase of the usage of PSPCipher source.
    A minor update to understand files tables of 6.30
    - 100X/200X/300X: new tables for 07g and 09g
    - go: uses the same table key as 100X/200X/300X
    No 6.30 keys are added, files from 6.30 can only be extracted in encrypted form.
    Also I have just updated the source code and compile, the program has not been tested.

    5.00 M33-7 Updater by Chiri_13:

    Many of you will remember who you had the CFW 5.00 M33-6 how annoying it was to activate or deactivate version.txt that would change the options to speed up the memory stick. Well our good friend on her day DAX took a mini patch that solved this little bug, but not brought to light not to be as important and not make too much however it is now necessary to enter the Store with PSNLover of must have seen the light of this Mini Patch.
