Hey, first of all it's just a tip, not requesting or anything. Second, to admins/mods, if it's wrong section then just tell me and I remove this post.

Right so if you already didn't know, I'm posting it.
If you want to ISO mod and got a JTAG/RGH and retail disc game, you do not have to copy the whole game onto your pc/laptop, replace files, etc. All you have to do is just put the moded files onto USB, plug USB into your JTAG/RGH, then just copy the files into the game directory, wherever it goes. It does work, you just need all the files required. I have done it for GH3 (Enabled Autoplay), WAW Nazi Zombies ISO Mods and GTA IV trainer.

Reason I posted this tip, is I see a lot of tutorials about ISO mods, if you got a JTAG, they give you steps to copy game onto pc/laptop then copy it back with replaced files.

So yeah hope it helps. Hope I managed to save your time, also sorry everyone on TTG if you already knew about it.
