pcem VS GPCS4

For emulation, you can look into PCem/86Box

Absolutely check out PCem for a closer to hardware emulation than dosbox, https://pcem-emulator.co.uk/

One option is to try PCEm https://pcem-emulator.co.uk/ which is a emulator for old computers that runs on Windows and Linux, I actually learned about it via this video https://www.youtube.com/watch?v=y9HP9W88Wew of a guy playing Sim Golf on his Windows PC using PCEm, this should be similar on Linux but I'm not sure if the SteamDeck will have enough power but maybe worth a try

For hardcore mode, compile PCEm - I think brew has most of the dependencies available ... https://pcem-emulator.co.uk/ - have fun!

You use 86box or PCem which are not virtualizers but hardware emulators so you will need a really fast CPU (especially in single thread). The advantage is that Windows 98 will be running on period appropriate hardware, since all of it is being emulated real-time.

QEMU [0] emulates many systems, including the 32-bit Intel architecture. For retro gaming specifically I can recommend PCem [1], which also emulates a wide range of sound and graphics cards, from IBM MDA to 3dfx Voodoo 2.

You could try it with PCem

The main dev of Orbital (Alex) has said that he is currently taking a break, if you're interested in another windows PS4 emulator GPCS4 can currently render some graphics and boot into one game, but it isn't really playable (~15fps), the best ps4 emulator by far at this point is spine.

Because you don't just have to figure out the software (software that is already not just a stepping through the debugger away from comprehension), but the hardware too. Even in the ps4 case, there's a world to reinvent (here the lines between emulation and virtualization may effectively blur though, since only "secondary devices" wouldn't be run directly)

There are, just none of them are worth using. GPCS4 can run one game, "We Are Doomed" at a very low FPS.

there is a legit ps4 emulator for windows but i dont think you are looking for it because it doesnt run at playable frame rate Inori/GPCS4: A Playstation 4 emulator just begin (github.com)
