I've tried last version in my R4 (i dont know if it is original or not) and i got black screen. Then i tried v0.2.4 and it worked!
I can confirm it is working in FTP mode and with Pkm Black 2! Thats a great tool! I only wanted to know why v0.3.0 isnt working with me (yes i've tried to DSDL patch but no luck).
