That’s what I was hoping for, but it didn’t work like that for me. After going through the bullshit to reformat my sdcard from exfat to fat32 (I did that think maybe that was my issue. That was a horrible mistake), I ended up nuking my card, because my emunand didn’t work and my saves (using sx save manager or jksave) wouldn’t transfer over. I’m now using atmosphere and starting new.On the main Horizon homescreen in Atmosphere or SX OS, hold R, and launch a game, and keep holding R while you choose the profile, until you get to the homebrew screen. You'll see that it's not in applet mode anymore, and GTA 3 will launch just fine.
