Switch doom64 limited run game cartridge type

[Scottier681]

Does anyone have factual info on what type of data is on the doom 64 LRG cartridge? I was wanting to know whether it is a ROM like older NES, SNES, N64 carts which are still playable 30+ years  or some degrading data storage which will not last even if stored for collection, preservation and future use. Anyone actually taken a switch cart apart and really know for sure? Especially the doom 64 switch cart. Any info or ideas?

It should be noted that ROM can degrade as well. It's perhaps somewhat less susceptible, but well, it's a physical format - anything physical can be destroyed over time.
