1. wood firmware supports only clean decrypted or encrypted roms. check you rom using no-intro.org nintendo ds dats before reporting any bugs.
2. any bug reports must contain a save file (except when the problem happens at the start) and detailed descriptions on how to reproduce the problem. "game 'xxx' sometimes freezes" is not bug report!
3. wood rpg is the main firmware. wood r4 is only an option.
4. i only have a 3in1 expansion pack. so no support for 3in1+, ewin or any other expansions.
