strtoul 54fc7320f9 *added new feature to force aspec ratio on games/channels (global and per game setting) (thx giantpune for help with disassemble)
*added refresh of partition size when activating wii games mode from none wii games mode
*fixed playback of some BNS banner sounds
*moved every allocation used during or after apploader to mem2 (fixes some memory overwrites problems by the apploader)
*improved detection of game partition when starting the loader without configs (fresh start)
*fixed remove of unused cached titles on wiitdb load
