Need some help...

I can't put the game that I downloaded through romulation... It says that something about a corrupted data or something ( I forgot the exact text)... I'm using an r4ds... Sorry for my english... And thanks in advance...

Have you unpacked the game from the rar file it came in?Read the common issues thread in this section.

Redownload the file again using download manager if the extraction fail.

Use WinRAR or 7Zip to extract the RAR file and put it on your formatted microSD
