GBA-Exploader/arm9/source/gbaldr.itcm.cpp
ApacheThunder a2e7393e3e Improve file browser ...
* File browser no longer displays "." directory while in sub
directories. Like original builds of GBA Exploader only ".." is a
visible while in sub directories.

* TTMenu is now a folder checked when looking for gbaframe.bmp if one is
not found in the other possible locations. This allows using gbaframe
currently setup with YSMenu if user also has that setup.
