The regional Phantasy Star Portable 2 servers are in the process of receiving a patch that will fix certain deficiencies in the servers' authentication checking code. It was previously possible to get online without having a valid Little Wing License. This flaw is being corrected. RubyEclipse, a member of the Sega Community Team, posted the following about the update:
"Good news - this update has just gone live!
To clarify again on the specifics:
As with any patch or update that affects connectivity, I'm sure there may be some people who have trouble getting online - so if that's you, please also feel free to contact us at http://help.sega.com for customer service if you're having any trouble with your code."
- All users now need the code granted within the retail copy of the game or which was automatically awarded when purchased digitally to access the online servers. This code has been updated, so you will need to download it once more. (Download history should work.)
- If you've already entered a code and are getting errors logging in, you can redownload the code and this should automatically take care of things.
- New users to the online servers from today forward should automatically download the new code, meaning they won't have to download twice. (I haven't been able to test this yet, but this is the dev team's intention.)
According to RubyEclipse's latest post, this update has gone live in the UK and needs "one final tweak" before it goes live in the United States.
