Why you need blank save files? If there's nothing it it, wipe it off, and try again. And make sure your WOOD v.1.62's save file extension setting/option is set to use .sav. WOOD supports 2 types of save file extensions. FYI: WOOD v.1.62 was the last WOOD released in 2013, it does not support the full NDS rom library to date.Or - Try patching the rom with this tool : http://filetrip.net/nds-downloads/rom-hacks/download-retrogamefan-ds-scene-rom-tool-v1-0-build-1205-f25536.html
