First there's a $300 hardware emulator of an NES that used an FPGA board (Analogue NT). Emulator isn't the right word, the FPGA is a programmable CPU, and it's made to behave hardware-perfect to an NES. After a few years of arms races Intel starts selling a ready-to-go FPGA board that absolutely dominate the market, then someone starts selling a conversion kit called MiSTer that lets it easily be re-jigged into thousands of arcade machines, or dozens of game consoles and home computers. Like snapping a Raspberry Pi into a kit, except the thing with an Intel FPGA they prefer is a 'DE10-Nano'.

Here's how well it it can be a 486, running stuff including Doom and Hexen.

Within 5 years you should be able to build a new FPGA system for $300 or less that can pretend it's a P3 with an early graphics card. This isn't the answer you wanted, but, it will definitely undercut capricous valuators.
