 Currently these are the patches applied:
 
+`inipath.patch` default ini paths include the home '~/.mame' directory and two relative paths '.' and 'ini'.  The relative paths are not helpful inside the sandbox, and the '~/.mame' contents shouldn't be overwritten with each new MAME release.  Instead the default ini search path is patched to '$HOME/.mame;/app/share/mame/ini'.  This will allow a default base ini in '/app/share/mame/ini/mame.ini' and can be overridden in '~/.mame/mame.ini'.
+
 `ldopts.patch` enables an option for the linker to strip debug symbols.
 
 `use-system-lib-flac.patch` works around FORTIFY_SOURCE compiler option that causes errors in the included libflac.
