*fixed reading game titles from disc header on fat32/ntfs/ext (Issue 2034)
*moved low mem and video setup for channels after loading the dol (fixes/corrects video mode, little video flash on startup of channel and might fix some other stuff. hopefully doesn't brake some channels) *removed duplicate memory flush/patches *code optimizations
