If you seriously want to set something like this up, you’re going to need a device that can emit the smells that you want.
This instance of a device looks like it uses atomizers hooked up to different tanks:
I’d imagine that one run as many tanks as one wanted.
One limiting factor is that scent isn’t going to immediately change when you change your virtual environment. I’d guess that emitting the vapor close to your face, maybe running a hose up towards it, would help. Probably want some kind of exhaust to purge the previous smell from the room.
Second, some form of computer control. Maybe some device that has relays controlled via USB. A relay is an electromechanical switch that can can cut power to an atomizer on and off, could run it to the atomizer.
Those guys sell USB devices with up to 64 relays. I haven’t looked, but it probably looks to the computer like a virtual serial port, takes text commands.
Then you need some kind of daemon running on the computer to send these commands at appropriate times.
And lastly, you need some way to trigger the daemon when the game is seeing some sort of event. Could monitor the game’s logfile if it has one and contains the necessary information – I recall some Skyrim-hooking software that does this – take a screenshot periodically and analyze it, or identify and then monitor the game’s memory, probably either a technique called library injection (on Linux, library interposers are a way to so this) or using the same API that debuggers use.
If the hentai game that your friend is after is Ren’Py-based – a popular option for visual novels, which many such games are – and the game includes the Python source .rpy files, which some do, then the game’s source itself could simply be modified. If it contains only compiled .rpyc files, that won’t be an option.
You’re going to need to obtain whatever scents you want to emit as well. You can get collections of essential oils – the aromatherapy crowd is into those – and mix them up to create blends that you want.

I’m not sure I want to know, but what is the context of this picture? It’s hentai isn’t it?

I have absolutely no idea. It’s an old meme. But since it’s hentai I think it is probably exactly what it sounds like.
