You can find technical specifications for the N64 Roms from websites that specialise in Roms and console emulators. You must be careful when downloading from free websites though as there is a risk of downloading viruses. Make sure you check on forums etc to ensure you are downloading safe Roms.
Most likely not, although you can't be sure of course. The chance is very small there is.
A good Emulater website, safe without any viruses will behttp://www.emulator-zone.com/. To get roms (Games) www.coolrom.com
Personally i wouldn't touch those websites, they are usually viruses. I think the websites are not viruses because my friends have a TTDS card and they download roms from a website for free and nothing has happened to their DS's. And I don't know what to do about that yet. Just wait for me to talk to my mate and I'll tell you.
The project 64 is a Nintendo 64 emulator that lets you play Nintendo 64 games that you download from websites.
Downloading ROMs for games that you do not own is considered illegal. Legal options include creating your own ROMs from games you own or getting ROMs from legal sources.
Jovan Roms was born in 1981.
No, only SNES ROMs work on SNES. You need a NES emulator to run NES ROMs.
You can not download legal video game roms.
well... you can only play gameboy color roms with lameboy, you can play nes roms with nesDs, sega roms with jEnesisDs or apprenticeminusDs and SNES roms with SNEmulDS
Hacks are distributed as patches, which you apply to the original roms. You get the original roms from your cartridge using a special tool.
