Storage and conservation of cartridge media

You can find most NES carts with box art and PCB scans here:
http://bootgod.dyndns.org:7777/

 

Cartridge, memory card(like n64) and console motherboard use CR2032 battery that you can buy easily everywhere. PC Motherboard CMOS batt is also CR2032.

Small form factor hardware (like gba and gb cart) usualy use CR1616 batt.

 

concerning plastic. The famous plastic yellowing/color degradation is due to a chemical reaction (actually a degradation) of cheap, low quality plastic. This issue can be slowed down/avoided by not keeping the machine/cartdridge in direct sunlight, since the UV rays hasten the process. This is quite widespread known.


Another factor in the yellowing that i've never saw mentioned is temperature. It's more than reasonable to say that said yellowings can start or (for sure) worsen because of overeating/high temperatures.

The bad about this, is that it is a process that is not possible to stop, and it do NOT only involve the surface, but the whole body of plastic. so no treatment trying to take out the surface will be useless.

One REALLY important thing to consider is that NOT ALL the Batches of plastic have the same caracteristics. It all depends on the batch quality. So 2 snes owned by the same guy, kept togheter in the same place on the same conditions can result in a pristine and a yellow machine.

Many yellow snes have top yellow and bottom pristine. This is because of different batches or because differently colored plastic Degrades in different ways.

In short the black Sega Saturn plastic wether it is as cheap of the snes one or not, will never experience such dramtic changes, while the PSX, due to its color might be prone to it.

Lastly, some people say that the yellowing is because of smokers... Now as a far as my diplom in chemistry allows me to understand, is BS. I think no place is THAT smoky.

hope it helps somehow. ask questions and i'll elaborate.

Edited: so in short, i forgot my suggestions. Keep plastic that is white/gray or such in a dark place not hot place like your garage might be. If your item is Black/dark grey or such, you should have no big worries.

edited again: I forgot to state, that bad plastic batches will get yellow NO MATTER WHAT YOU'LL DO. You can only slow down the process. So A SNES that is not yellow today and has been used intensivly should be highly valued since even a brand new boxed one could get yellow in far shorter time.

...ALL of the ingredients listed will react with 'plastic', some very aggressively, including water, which of course the best universal solvent known to man!

Hope this helps.

 

first of all i'm ready to bow to any superior knowledge. and you might have better knowledge than me in chemistry, no problem, really. I'm well aware of the experts warnings about smoke and yellowing, but as for working experience and personal reasoning appears ridicolous. So personally i do not believe it even tought people with higher degrees than mine might say the opposite, i think thay talk mostly in theoretical way or in limit cases.

so:

i'm well aware of the effects of those chemicals on plastic, and what comes out of cigarettes.
BUT i don't think that people can survive in a room in wich there's enough of these chemicals around to impact the console's plastic . no seriously, we are talking of less than ppm quantities present in the smoke. and we do not (i think) directly blow on the console... also most of those chemicals are highly volatile so will float to the ceiling of the room. i do HAVE a diplom in industrial chemistry BTW.

i might be wrong, but i keep thinking that normal level smoke (compatible with staying there without feeling sick) in a room with normal aeration will not reach this bad levels able to impact the console.

in any case the yellowing case i think are at the least 99% due to the plastic, not because of the smoke.

also i wonder how deeply "smoke yellowing" would manage to affect plastic. it would probably affect mostly the outside surface of plastic i guess so in case it's REAL smoke yellowing, bruising away the plastic surface might bring back good color...


i would try it gladly, but i still have to find a SNES yellowed because of smoke... if anyone have one might be interesting for him to try.

 

You can turn yellowed plastics to white using 80% concentrated H2O2 IIRC. It's on the internet, they tried with an Amiga and worked, at www.elotrolado.net has been prooved too. And it isn't a matter of UV or temperature, people who left they're sneses at the closet, with no light at all and when they got it from the closet 15 years later it looked like a lemon.

 

Read my post with more care. I have elaborated about that and plastic batches and much more.

hydrogen peroxide might help, but not with all kinds of yellowing and all kinds of plastic. Also details and writings on the console/cart might get deleted and color be changed from anything to white or other colors.

so better making a test on a small unseen part before trying it on your beloved console.

 

I just opened up the 4 Zelda carts I have and none of the batteries show any
sign of corrosion. I have not checked any of the Zelda 2s, but Legend of Zelda
still has my 20 year old save games.

 

A suggestion for a yellowing SNES would probably be a custom paint job. Obviously not the best solution, but no one wants one of those ugly yellow SNESes.

I think aside from corrosion, you also have to worry about the charge dieing. There is the rumor that booting up the game regularly will help the battery keep its charge longer. Any truth to this? From what I understand, it helps with CPS2 boards, but that's a different type of battery, right?

On the subject of labels, Atari 2600 labels come up all the time. You've got the infamous Acti-plaque, where black spots show up all over the label. A significant number of Activision cartridges have this problem, and the only game I own that does not have Acti-plaque is Beamrider.

Is there a life-span for these cartridge games? I've heard that Famicom Disc System games are prone to gradually demagnitizing over time. I'm not too familliar with the inner workings of an eprom, prom, and whatever else is used to store program data inside of cartridges to know if my Channel F and NES games will run 30 years from now.

 

batteries are supposed to last really long. leaking problems are usually due to low quality brand battery, or due to water/wetness.

I've been thinking about how to store properly carts protecting them from light, wetness, smoke, dust etc

and my best bet for long term preservation of the cart+insides from rusting/oxidating and wetness is this one:

http://www.ciao.it/Macchina_per_sottovuoto_Magic_Vac_Elite__274477

this machine is used to take off air from aliments and then wrap them in plastic by melting the bag's side.

these machines are really cheap, and the vacuuming is quite bland. Wrapping them this way and storing in boxes would for sure protect from light, wetness, dust, and smoke.

if you are a perfectionist or if the item you want to preserve is too big (like whole console/ cardboxes etc) you might try to use those boxes that are waterproof (the one that have a layer that looks like "petrolled" (can't find the english word) that are usually given in post offices for long shippings) and for being extra safe maybe adding silica gel to take care of excess wetness.

what do you guys think? good idea?

 

You can replace adhesive on labels using this great stuff, its the stuff they use to make labels in the first place.

Great post, excellent read!!

 

wow i was almost 100% RIGHT! different batches, degradation, heat and UV rays as i stated even the same suggestions i gave. woooowwwww
