The wait is finally over!  Dark_Alex has released DCv6, so we can all relax (a little) regarding the new TA-088 mobos wreaking havoc in the CFW scene…  Also, the new version allows you to boot from the memstick as well as a new interface! Changelog after read more.

The new TA-088 Motherboard/CPU issue has been examined, and DA is working on it!  The problem seems to base from not just the new motherboards, but the new CPU’s being installed.  Some TA-088s can be flashed, so it’s kind of a gamble at this point.  Dark_Alex has stated that the problem has to do with [...]

Judging from the comments made on PSPGen (The GEN/Miriam Custom Firmware homepage) Version 4.00 GEN might not see the light of day as a public release. Although a beta version of 4.00 Gen has been completed by Miriam, Team GEN might keep this release internal as they are aware that Dark_AleX and team M33 [...]
