Hacking WiiFLow only showing games installed from disc, not ISO's

[Kragar]

so yeah. I used the Super Smash Bros. BRAWL thingy, followed a bunch of tutorials on softmod Wii U.
I guess I did something right as I can install games in WiiFlow with discs. For the life of me I can't find a video tutorial on showing how to put the .iso or .wbfs on external HDD. I tried so many things, using the proper name, game code. Using Wii backup and Game manager. It just doesn't work for me. I even tried burning an iso using imgburn, got an error. After several hours of looking around I seriously can't figure out why I can't have WiiFlow see my iso's I manually put on other than the ones it created from real game discs.
PS: my HDD is NTFS, simply in case I have a game bigger than 4GB

Ntfs works just fine. Put the isos into this directory: hdd/wbfs/
And try refreshing cache in wiiflow

Ok so I got it working but the graphics are jagged edges, pixelated compared to using the Wii Dolphin emulator in which the games look absolutely flawless, I tried a few different game modes to see if it would improve it but it hasn't. Any thoughts?
