From 152847977a420487d9c3728841101ef708e41373 Mon Sep 17 00:00:00 2001 From: Michael Sparmann Date: Sun, 2 Jan 2011 23:16:27 +0000 Subject: New port: iPod Classic (also known as iPod 6G/6.5G/7G) Major known issues: - No bootloader yet - No support for the first-generation 160GB CE-ATA hard disk drive yet - Audio playback is slow, only FLAC seems to reach realtime git-svn-id:
