PS3HaX Developer CrashSerious has updated his “One” application and has fixed many of the problems you guys have had, here is a quote from the update:

Tonight, to celebrate the last binary date of the century. We bring you a update to one.

Simply, it updates memory card support and works on the following systems:

3.55 MFW Retail/CEX
3.41 MFW Retail/CEX
3.15 MFW Retail/CEX

3.55 MFW Debug/DEX
3.41 MFW Debug/DEX
3.15 MFW Debug/DEX

(Note: one uses “state of the art” firmware detection to apply patches needed, spoofing simply can not fool it.)

Now not only do memory cards work… but those of you who are on MFW 3.15 can use it too. We told you we didn’t believe people should go without features!

PS3 Developer CrashSerious has released an application which enables you to boot PS1 games(backups), here is a quote from the read me:

We present to you an app that is as simple and to the point as
its name:

one

one boots PSX game disks, *ANY* psx game disk, even a game
reported to not work previously:
SLUS-01104 NFS: Porsche Unleashed

Requirements to use one are pretty simple, MFW 3.41/3.55
(all variants).

Simply install one, and run it with your PSX cd in the drive
the game will start after a few seconds. If you do not have a cd
in the drive when you start one, it will exit to XMB.

What doesn’t work:
Selecting or loading PS1 VMC’s
Loading from HDD, sorry… you gotta have the disk people.

Q/A, FAQ, aka Before you ask, look —/

Q: Multiman does this, why do it separately?
A: First, just because we wanted to. Secondly, because not
everyone runs Multiman, or (crazy as it sounds) even has a
backup manager installed. Third, we don’t like people having to
choose whether or not to lose functionality.

Q: How do I use this?
A: Install the pkg, insert your PSX cd, run one.

Q: How do I install a pkg?
A: LMGTFY

This is the first true app that has been entered into the so called monthly PSX Scene competition

Anonymus famous for his work on porting the ps1 emulator that is the PCSX to the ps3 has now released the source code for it allowing us the user to make modification needed in order to improve its compatiblity with the PS3 the emulator currently supports .iso, .bin, .mds and .img formats and audio such as CDDA XA. That’s not all this also has a 2 player functionality unlike most emulators and runs at full speeds at an early stage to quote
