Have you tried with NX-Shell? It's a file manager, you may be able to locate the game folder and delete it from there if there's any remaining files. If I'm not mistaken the name of the folder is the game ID (you may be able to google it, or maybe it's the name of your NSP file).I was transferring an NSP with goldleaf (usb) and it disconnected during the transfer. It showed the nsp as an unidentified program on my home screen which I managed to remove by going into the software settings and remove the data. However now when I try to re-transfer it with tinfoil or goldleaf I get an error msg. I'm thinking there may be remnants of that initial transfer on my sd card. Can I somehow purge my sd card of its files or any ideas how to resolve this?
