You will need a good emulator and as only one actually runs proper games you will have to download UltraHLE, (this is your first step towards a huge phone bill, you have been warned.) UltraHLE-Z comes with an aditional configoration util, this can now do multiplayer, even on two joypads!! This is the best and so this is the only emulator on my downloads list. There is an extra control pannel which you can download but I dont recomend it as it is buggy and rarely does what you ask of it.
Step 3 Games
You can find links to many games that are avaiable for download, and work on my N64 downloads page, these are only links to other sites games, please e-mail me if any of these links are broken. The games are usually 10 megs and take about an hour to download if you have a good connection at about 56bps, This is where you get your huge phone bill from!!!!! The wait is worth it as long as you make sure the game works before downloading it.
Step 4 I got the game, how about some cheats
To enable the cheats in the UltraHLE ini file you simply find the game and remove the slashes at the left hand side of the cheat, to disable cheats simply do the opposite.
