The following (as far as I have tested) works on all difficulties at any point in a game with one or more natural wonders, and I cannot find it mentioned elsewhere on the forum. I haven't tested it on multiplayer. Unlimited happiness applies to all civs, while unlimited gold only applies to Spain. Simply press ctrl+z (the first time you press it it will reveal the whole map, introduce you to all city states, all empires, reveal all resources and discover all natural wonders. If you are spain, you will get a couple of thousand gold from this. If you press ctrl+z again, no matter what civ you will "rediscover" those natural wonders, and regain the happiness benefit (the game will say you have -7 natural wonders yet to discover, say). If you are Spain you will gain approximately 500 more gold. Simply repeat the process for unlimited happiness and gold (if spain). After you have the required amount of happiness/gold, save and reload. You may continue playing without saving and reloading, but you will receive no notifications to choose science, production, social policies etc. Once you reload you will no longer be able to see resources you have not discovered the technology for, but that's all in the spirit of the game
Tips for quick usage:
Calculate the amount of times you need to use ctrl+z and then type it in quick succession, then use escape to cycle through the notifications quickly
The two screenshots below show the use of this hack for Rome (unlimited happiness, limited gold) and Spain (unlimited gold and happiness) in Deity.
Hope this helps someone
