Reddit mentions of GGG0030 Video Game Cartridge Dust Cover 6 Pack: for Nintendo 64 Games (N64 Cart Protector Sleeve Cover or Case)

Something like this might be good. I don't own an N64, but I use something similar for some of my SNES cartridges and they're quite good.

After buying a new N64 game, I clean it with rubbing alcohol and then I put it in one of these dust covers http://www.amazon.com/Global-Game-GGG0030-Nintendo-64-Cover/dp/B00AAIDNTW/ref=sr_1_4?ie=UTF8&qid=1374584922&sr=8-4&keywords=nintendo+64+cover

$6 Amazon Prime

These dust covers are actually a third party kind I found on Amazon. I think Nintendo shipped them without any kind dust protection back in the day, probably hoping to sell accessories.

I definitely agree with you about that there's are misperceptions about the quality of the N64's library. Sure, not every game is Super Mario 64, but there's still a lot of fun games or games worth playing because they really tried something unique.

Yup! http://www.amazon.com/dp/B00AAIDNTW/?tag=googhydr-20&hvadid=49480724816&hvpos=1t1&hvexid=&hvnetw=g&hvrand=9335099348298797600&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_51xcwpmiip_b

North America, I bought them on amazon. http://www.amazon.com/gp/aw/d/B00AAIDNTW/ref=mp_s_a_1_1?qid=1380744664&sr=8-1&pi=AC_SX110_SY165_QL70

I'm not sure what the best way to display them is (i have a drawer in an old tv stand that happens to fit them perfectly), but these are a must have for protecting cartridges from dust or whatever:

You can get these dust covers (similar to the ones for SNES) made by global game gear. They're 6 covers for $8 and have Prime Shipping.
