今天官网有个新帖子有点意思,Mister的作者Sorgelig的观点是

There are limits where FPGA can be used regardless if it's FPGA in MiSTer or any other boards.
PS2, Dreamcast and later consoles/computers use very high clocks not reachable on FPGA. Also chips became more complex and less low-level technical info is available. To create the system in FPGA you need much more technical low-level info than for software emulator. And more modern system - more hard to find such info.
FPGA will remain at the 90x systems emulation in foreseeing future.
Also there is no real benefit of FPGA against software emulators on later systems. They are 3D systems where GPU is more useful than FPGA. Also these systems aren't depend on cycle accuracy.
So FPGA is pretty much fixed for pre-2000 systems.

More modern FPGAs may give some advantage for later computer systems such as PC or Amiga. Saturn is on very early stage, and PS1 is in unclear state too - so if they will fit into MiSTer then it will be pretty much the top of possible.

FPGA won't be better on PS2 emulation or anything more modern.

大意是，就目前而言，不管是Mister或者是其他以FPGA形式仿真游戏机的方案有些固有问题导致很难实现PS1/SS 以上级别游戏机的实现。大概是PS2,DC等有着FPGA很难实现的高频率，更复杂的芯片，缺乏比较底层的技术细节信息（相较于软件模拟的方式需要更了解底层细节）而且越是新的系统越难找到相关的信息。

所以在可预见的未来，硬件仿真最多也就止步于PS1, SS这个级别了

首先，"硬件模拟"这个词，对MisterFPGA来说是不完全正确的，而应该叫"逻辑硬件重实现"。
因为本质上，是在无官方硬件设计原案的情况下，仅通过逻辑分析仪或少数流出的官方文档对于特定I/O功能的设计描述，进行用VHD ...

老哥很专业啊。 以后肯定会有基于更强大板子的类Mister实现。只是就当下来看，在S大描述里可预见的瓶颈，是不是还会有其他能给我们带来惊喜的东西，还是就此止步于ps1,ss（就这两是否能达到sfc,md之类的成熟程度都还没谱），这是个问题

其实有的人完全没有必要戾气这么大，Mister本来就不是和盒子，树莓派之类基于软件模拟器“竞争”的一个东西。虽然“看”上去都是“多机种模拟器”，但稍微懂一点技术得应该都清楚Mister的独创性。
FPGA，一个出来也有些年头的东西，被一些既有技术又喜欢玩游戏的geek捣鼓出来些类似analogue nt, mega sg的专一机种的商业产品，能卖几千块还销得不错，肯定有它的优点。
而Mister作为一个开源项目，只要一千多点就能横跨多机种，而且效果也很不错，社区也活跃，只是de10nano本身就是个性能和价格妥协的选择，有它的天花板也很正常。
