If your PSP is on 6.39 and you just can't be bothered to update or just can't, neur0n has you covered.
The neur0ner has updated his 6.39 lineup for those still on that particular firmware. It's a small fix for those experiencing issues using the "SpeedUp MS" option of the firmware. Other than that, the Text Color option has been added in the Recovery Menu. Like the name says, you can change the color of the text within the recovery menu from the standard red, to green or even blue.
Remember that the ME flavor is for those who have a permanently hackable PSP, (Phat, Slim non TA-088v3) and the LME flavor is for everyone else. You can pick up the latest version of the 6.39 CFW below. https://twitter.com/#%21/neur0ner/st...61600370614272
