光盘介质在大厂主机游戏领域或许已经过时，但在 [Emmet] 心中并没有——他专门打造了一台 DIY 游戏机来使用光盘介质。不是花哨的蓝光或新式 DVD，而是 Orange Book 标准的老式 CD。
当然，这些光盘装不下现代 AAA 大作，而他用的单板计算机上的 Intel N150 处理器也跑不动这些大作。不过这没关系，因为这台机器能处理的内容足足有几十年的存量。为此，主板运行的是 Batocera——一个专为 x86 复古游戏而生的 Linux 发行版（也支持 ARM，但这里不重要）。
他使用 ESP32-S3 通过 BLE 驱动自定义无线手柄，每只手柄里的算力甚至比这台机器模拟的部分复古主机还要强，但效果很好。与一些只是排队加载游戏的卡带项目不同，这台机器上的 CD 确实存储了 ROM 文件和一个 shell 脚本，可将游戏放入正确的模拟器库中。我们可能更倾向于自动运行，但这是 [Emmet] 的主机，他按自己喜欢的方式调试好了。
在我们看来，这个项目真正出众的地方，是 [Emmet] 为 CD 定制的标签和为光盘盒设计的封面艺术。这让它看起来像一台真正的游戏机，而不只是一台连上电视的 PC。3D 打印的外壳同样功不可没。
无论是出于怀旧（如本项目）、对廉价存储的需求，还是想把它接到 NES 上的奇特愿望，光盘介质似乎正迎来一个小高潮。说到怀旧，我们不得不承认：CD 已经成为怀旧之物了——它们不是才刚刚取代黑胶唱片吗？

Optical disc media may be obsolete in major console gaming, but not in [Emmet]'s heart—he specifically built a DIY game console to use optical disc media. Not fancy Blu-ray or modern DVD, but old-style CDs from the Orange Book standard.
Of course, these discs cannot hold modern AAA titles, and the Intel N150 processor on the single-board computer he uses cannot run them either. But that does not matter, because there are decades' worth of content this machine can handle. To this end, the board runs Batocera—a Linux distribution born for x86 retro gaming (it also supports ARM, but that is not important here).
He uses an ESP32-S3 to drive custom wireless controllers via BLE, and the computing power inside each controller is actually stronger than some retro consoles this machine emulates, but it works well. Unlike some cartridge projects that merely queue games for loading, the CDs on this machine actually store ROM files and a shell script that can place games into the correct emulator library. We might prefer it to run automatically, but this is [Emmet]'s console, and he debugged it to his liking.
In our view, the truly outstanding part of this project is [Emmet]'s custom CD labels and the cover art designed for the disc cases. It makes it look like a real game console, rather than just a PC hooked up to a TV. The 3D-printed enclosure deserves plenty of credit as well.
Whether driven by nostalgia (like this project), the need for cheap storage, or the quirky wish to hook it up to a NES, optical disc media seems to be enjoying a mini-boom. Speaking of nostalgia, we have to admit: CDs have become nostalgic items themselves—they only just replaced vinyl records, didn't they?
