破解世嘉土星 CD：20 年之后
Sega Saturn CD Cracked after 20 Years
2016 — 2022，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
这段视频展示了黑客 Professor Abrasive 如何在二十年后破解世嘉土星（Sega Saturn）主机的光盘防拷机制。他逆向了光驱的协议与链路层，最终做出 Satiator 设备——无需改装主机即可从外接存储运行光盘镜像。视频以通俗语言完整呈现了整个逆向工程过程。
为什么经久不衰：它既是逆向工程教学的经典范例，也触及数字保存这一长期议题：封闭平台上的软件文化，几十年后可能只剩靠黑客的'备用钥匙'才能留存。

视频是极佳的逆向工程入门讲解
太棒了。视频避免了过于技术化的语言，基本讲清了逆向工程的全过程。这是我很久以来见过的最好的逆向工程讲解。

This is amazing. The video avoids too technical language, and basically explains the whole process of reverse engineering. I think this is the best explanation of reverse engineering I've seen in a long time.
呼吁大公司把软件文化保存纳入平台责任
我真希望苹果这样的大公司里有权影响企业文化的人能看到这个，并受到启发去思考文化保存。我认为让这类破解不成为我们数十年后保存当代文化的唯一钥匙，应当成为企业责任和平台守护的标准做法。否则我们作为全球文化可能会真的迷失、失去历史。要真正让保存合法化，未来需要某种官方的模拟和数据提取能力，谁知道会不会有禁止逆向工程的糟糕立法。软件分发越来越 ephemeral、下载化，个人数据又碎片化在云端，总得有人来做这件事。

Wow. I certainly hope someone with a lot of power over company culture at, say, Apple is watching this. And that they get inspired to think about cultural preservation. I really think it should be a standard act of corporate responsibility and platform stewardship to make it so that work like that of Professor Abrasive's, is not the only spare key we have to current culture a few decades down the road. We as a global culture just might be really, really lost and bereft of history if that was to be the case. I frankly think that Apple under Tim Cook is in a historically unique position of making cultural preservation of games and software feasible and something built into the whole social and legal contract of proprietary, locked down platforms. It's not like Sony is going to lead the way with the PlayStation? I mean, to really make preservation legit, there needs to be some sort of useful official emulation and data extraction capability down the road. For all we know now, there might be terrible legislation that prohibits reverse engineering in a lot of jurisdictions. There's of course a lot problems to solve, with all the crypto and stuff, and licensing, but someone should be on this. Especially since software distribution is becoming all ephemeral and download based! Not to mention the cloud fragmentation of personal data.
讽刺 DRM 对硬件的过度阉割
了不起的工作。也凸显了 DRM 支持者常常偏执到不惜如此大费周章地阉割硬件。破解 DRM 就像治好了精神病一样。

Amazing work. Also highlights how paranoid DRM proponents often are going to such lengths to cripple the hardware. Breaking DRM is like finding a cure for insanity ;)
梳理土星运行备份的各类现成方案
土星玩备份光盘已有多种方案：Pseudo Saturn Kai（烧录卡固件，免改装、便宜）；Phantom 芯片（类似 PS 的 modchip，接在光驱排线上）；Satiator（视频中展示，插在主机背面 VCD 口，免改装）；以及各种光驱模拟器如 TerraOnion MODE、Fenrir、Rhea & Phoebe（替换原装光驱）。
mewse-hn查看英文原文
Saturn has several options for playing backups: Pseudo Saturn Kai: a firmware for the pro action replay cartridge that will boot non-official discs. Affordable and no modding required. Phantom mod chip: like a classic playstation mod chip, but it plugs into the ribbon cable between the optical drive and the main system board. It needs one wire other than the ribbon cable, to provide 5V power. Satiator: As shown in this youtube video, plugs into the VCD port on the back of the system and runs backups with no modding required. Optical drive emulators: TerraOnion MODE, Fenrir, Rhea & Phoebe, these all replace the CD drive in the stock console.
澄清：破解早已发生，视频做的是光驱模拟
补充信息：土星的拷贝保护其实在 90 年代下半叶就被破解了。我 90 年代末就装了 modchip，几乎所有游戏都有解锁区域的 ISO 镜像可烧录到 CD-R。这个视频的工作是解构光驱协议和链路层，以便用闪存做光盘模拟。

Ive seen this video pop up again and again over the last 5 years. I have 1 question: when/where can I buy one!
