NeoGamma WAD is likely a specific WAD file that contains a custom level or set of levels created by a game modder. Without more information, I couldn't find any specific details about this particular WAD file.
⚠️ The WAD itself is not the full NeoGamma app. It’s just a launcher. You still need boot.dol or boot.elf in /apps/neogamma/ on your SD card.
NeoGamma WAD = nice shortcut channel, but only install it if you have Priiloader + BootMii, and keep the actual app on your SD card.
Insert the SD card into your Wii, turn it on, and open the Homebrew Channel. Launch your WAD Manager (e.g., YAWM Mod). Select Device: Choose "Wii SD Slot".
Change the second line to your media source, and choose "Load Game" on the first line. NeoGamma vs. USB Loader GX
