The difference is that you can still buy the MP3s and DVDs in a format that is playable on modern hardware.
Whilst with ROMs it may be that the original hardware is harder to get hold of. Not really the case with the N64 but with Arcade ROMs its a whole different ball game because some of the boards simply suicide if the battery runs out (without emulation or reverse engineering some of these games would already have been lost forever). Also with the Dreamcast and the Amiga CD32 there is a large hardware failure rate so whilst you may still be able to buy a device from eBay, you may not be able to in say 10 years time. Then there are games on magnetic media that simply deteriorate with time. I've bought boxes of thousands of Amiga and Atari disks in the past where only a few dozen still work.
Certainly, I'm not saying that I agree with the existing laws. I don't - they need to be vastly overhauled. I'm only stating my non-lawyer understanding of what the laws currently are, not what I want them to be. The DMCA took away some rights we used to have, to try to accommodate the new technology we have, but IMO overshot it.
These statements are great for in court arguing for changes to the law, but feel like flimsy excuses for when individuals use it as a rational just to entertain themselves. "I'm, um, uh, preserving culture! Yeah! I'll go with that.".
Most arguments in favor of piracy just seem like excuses to rationalize doing what we want, ("I wouldn't have bought it anyway","They make enough money", "They charge too much", "They owe me for X or Y", "I'm just testing to see if it works on my device", "I don't even know if I'll like the game", "They're scumbags of a company and I don't want to support them", "It's not harming anyone. Well, not any human. Well, not harming them too much anyway.", "The law is corrupt", "We need to stand up for the public's rights.", "It's not available in my region", "It's out of print", "There's no way I can acquire a legitimate copy - I would if I could", "They're getting free advertisement anway", "Their monetization method stinks", "and besides... if I don't do this, it could be lost forever! I'm preserving history!").
I think it just boils down to, "I'm going to do whatever I want, and how dare you tell me it's wrong!". The rest is mostly just self-justification/rationalization of what was going to be done regardless - either after the fact or before-hand to work ourselves up to it. People want each other to turn a blind eye to "slightly" wrong behavior so they don't feel bad for doing it, they want to be joined in that behavior so they feel okay about it, and even want to be patted on the back and told that behavior is not only acceptable, but heroic. But self-indulgence is not heroism, no matter how we dress it up.
If we're arguing for changes in the law, then these statements make sense. But if we're talking motives of individuals, then we need to first raze the potemkin villages.
Some of these I sympathize with - the "I already own it, why should I have to get it again for a different console?", "It's out of print or only on ebay for outrageous sums of money", "It was never brought to my region". But I try to understand in my mind what reasoning is just excuses I'm using to get what I actually want, and which reasoning is actually an ideological stance. Obviously I don't know other people's motives, but it's extra hard for me to believe it's ideological stances if they're just using it to play videogames.
In response to your comment about archiving, the Internet Archive (regular humans like ourselves) argued for and won additional exemptions to the DMCA (as of 2010, it's now a permanent exemption). This benefits legitimate archivers.
You are allowed to circumvent DRM and encryptions and such if you are doing it on:
- "Computer programs protected by dongles that prevent access due to malfunction or damage and which are obsolete."
- "Computer programs and video games distributed in formats that have become obsolete and which require the original media or hardware as a condition of access."
So that would most likely cover SNES and NES cartridges (and your Amiga/Atari stuff), and probably cover N64 cartridges as well.
It still does not cover downloading ROMs. Only bypassing the DRM if the format is "obsolete" and "require the original hardware as a condition of access". This is a DMCA exemption - downloading or copying ROMs other people have bypassed is still infringing copyright.
I had forgotten about these exemptions. In that case, my earlier statement is wrong:
"If you harvest your own ROMs, and in doing so break encryption (even simple encryption), it's 100% illegal."
It should be:
"If you harvest your own ROMs, and in doing so break encryption (even simple encryption), it's illegal, unless they are 'distributed in formats that have become obsolete and which require the original media or hardware as a condition of access.'"
There are also legit copyright exemptions for educational or research purposes (including "private study"), which may come in handy for game designers. This includes some exemptions for duplication (which might include downloading ROMs). But I don't think we can just pretend all of our game playing is "research" - there's a set of factors that need to be weighed for 'research' to count as 'fair use'.
Still, the exemption for obsolete formats is a big step forward, as individuals, because it gives us back the right to format-shift for private use our older games from aging hardware.
We still have to do the format-shifting ourselves. Downloading a ROM of a game we already own is still infringement, as far as I can tell - but I'd love to be proven otherwise!
(my desire to play my N64 games on computers trumps my desire to always win arguments )
