Homebrew WiiFlow + Retroarch mame2000 trouble... again

[vEN2]

Strange things. I want to play mame2000 thru WiiFlow, which is based on 1.3.3. Roms stored on USB drive. When i load rom from wiiflow, i gets a Stack Dump Error.

But, if roms stored on SD card (same folder line), rom runs fine.

I just can't get, why Retroarch refuse to load roms from USB drive thru WiiFlow. Folders are OK, plugin .ini is OK too. Maybe i missed something

P.S. I have some RA plugins, which based on 0.9.9 versions. They loads fine. i deleted all configs from 0.9.9, but that's did not make anything...

P.P.S. Standalone mame2000 works with USB drive fine

P.P.S My WiiFlow folders stored on USB drive
I used 2 ways to run mame2000 .dol file

If:
dolfile=retroarch-wii/mame2000_libretro_wii.dol
Than is gets Stack Dump error on USB drive. From SD card games loads, but configs are empty and did not save.

If:
dolfile=sd:/apps/retroarch-wii/mame2000_libretro_wii.dol
Than is gets Stack Dump error on USB drive, but from SD card games loads and my configs/controls loads/saves fine.
