Coldbird is a European developer who became known in early 2011, are in line with the help of Virtuous Flame, a HEN for 6.35 firmwares and 6.30/31. Subsequently, and always accompanied by Virtuous Flame, he offered to different users Custom Firmwares (tagged PRO) intended mainly for PSP inflashables. Several went to the pan firmwares: 6.20, 6.35, 6.39 and, more recently, 6.60. Several programs for Custom Firmware PRO also appeared: the popsloader, the permanent patch for the PRO or the 6.20 IPL Flasher for 6.39 and 6.60 PRO. A larger project was also in development: a review of C Custom Firmware PRO, allowing players to play online (meaning infrastructure) in games normally playable only ad hoc, without using Xlink Kai or ad Hoc Party.
The developer also took part in the PSP Genesis Virtuous Competition with Flame, and thanks to Custom Firmwares PRO, pocketed more than $ 1,000, including 300 offered by psp.

Custom Firmware PRO ...
After a well deserved holiday and a few weeks of development, the European developer yesterday posted a message on his blog in which he described the progress of the encoding mode of Online 6.xx PRO-C. Unfortunately, some people have verbally attacked the developer and his work through the comments, the message said. For Coldbird, this was the straw that broke the camel's back.
So after a night of reflection, he made his decision and officially announces its withdrawal from the PSP scene. He stated that he is the only member of Team PRO to leave the scene, the team is not dissolved. He also wishes to thank everyone who supported him personally or Team PRO in general.
As regards its ongoing work, Virtuous Flame resume the development of Custom Firmware PRO, supported by Neur0n, and everything about the online mode was assigned to Codest (PRXShot, resumption of
Game Categories), which will take over the project hands. We do know, however, if, if, hopefully, he would arrive at a result, he will put it online in his name or send it to Virtuous Flame so that this feature made its way into the PRO Custom Firmwares .
The now ex-member of the PRO Team joins Red Squirrel, Dark_Alex, Yoshihiro, GENyUS and many other big names in the circle - not so close that - the developers who, for one reason or another, left the scene PSP.
We can only wish a good continuation to the developer and thank him for his contribution to the scene.
