So, I have this technique that works pretty good for renting games, legally, and for free! Been using this technique for a few months now, and its been working great. No need to download ISOs, no need to waste bandwidth downloading ISOs, no need to mess with firmware manipulation to use ISOs!
It's simple:
1. Goto your local GameStop.
2. Check out the used games.
3. Used games offer a 7-day "return" policy.
4. Just buy a used game, try it for a week, and return it when you're done with it.
5. If necessary, just return it on the 7th day and re-buy it, preferably at a different store (where I live there are well over 10 GameStop stores within a 5-mile radius).
Most GameStop employees are chill with this, and as long as you make friends, they'll have no complaints with you returning used games every week or so. Rotate GameStops every time and they won't even bother mentioning it.
I find I get bored with most games after 7 days anyways, so this technique works great for me. If it's a really good game, I'll just keep it. But it saves a LOT of money in the long run...
Don't know if people already knew about this but figured I'd post it anyway! Good luck!
