:lol自己常玩的游戏总知道吧！看游戏后面用的是哪个核心，拷贝进去就完了，都运行一次没问题，其他的就可以删除了
为了兼容性，我觉得都解压算了
如果你想知道什么rom需要什么bios，就去看romdata文件
如果你想知道bios怎么设置，就去找对应游戏的bios说明书，或者直接看英文也行
这些应该是BIOS AND DEVICE，有些游戏不仅需要BIOS还需要DEVICE，所以不建议精简，全套应该不大，可以创建个文件夹额外保存。
如果你有强迫症那就如楼上所说，你去看DAT数据文件，看你需要的游戏依赖哪些BIOS 和 DEVICE。

一看就是282最新的BOIS全集，没有说明吧，只能是自己研究一下吧，大部分BOIS文件基本用不上，常用的BOIS文 ...
猫大侠，这是哪个版本，大字体看起来真舒服
主要是neogeo.zip和pgm.zip这俩常用

这一大堆文件，全复制过去还占地方，不复制还用不了，挺头疼啊
等你用的时候找不到更头疼
这个很久以前就能查到了，可以参考一下：https://docs.libretro.com/library/bios/
这是英文的，不知道有没有中文，正常所有你想知道的，这里都能查到，也能搜索的。可以用edge打开直接翻译。
BIOS 、device
https://docs.mamedev.org/usingmame/aboutromsets.html
--------------------------------------------
With those basic principles, there are two other kinds of set that will come up in MAME use from time to time.
First, the BIOS set: Some arcade machines shared a common hardware platform, such as the Neo-Geo arcade hardware. As the main board had data necessary to start up and self-test the hardware before passing it off to the game cartridge, it's not really appropriate to store that data as part of the game ROM sets. Instead, it is stored as a BIOS image for the system itself (e.g. NEOGEO.ZIP for Neo-Geo games)
Secondly, the device set. Frequently the arcade manufacturers would reuse pieces of their designs multiple times in order to save on costs and time. Some of these smaller circuits would reappear in later boards that had minimal common ground with the previous boards that used the circuit, so you couldn't just have them share the circuit/ROM data through a normal parent/clone relationship. Instead, these re-used designs and ROM data are categorized as a Device, with the data stored as a Device set. For instance, Namco used the Namco 51xx custom I/O chip to handle the joystick and DIP switches for Galaga and other games, and as such you'll also need the NAMCO51.ZIP device set as well as any needed for the game.
