I'm an absolute noob at this patching stuff so i don't know what i'm doing wrong... i want to patch 6111 - Pokemon Black 2 (US) (frieNDS) with the moon black 2 patch and i don't have a access to a pc so i'm only using android to patch this with rom patcher and i've already unzipped the .7z file and used the .nds file with the patch but when i press the patch botton it says XDELTA3:input/output error. I don't know what to do and i'm sorry if my sentences are weirdly put,english isn't my first language so i'm not too good at it
