Ok here is what i understood :
1=Download game
2=download eboot.bin file of that game or fix of the game
If your using the eboot file use step number 3
3=Replace Original eboot of the game(found in game folder)with the one you just downloaded
If your using fix file use step 4
:
4=Copy the fix in your external hdd,usb and install it via install package files(Just like the way you install multiman)
5=Copy the game to internal hdd and fire it up using multiman
Hope i helped you
