Setup
Five short steps from the Windows installer to your first boot, plus the spec sheet to check before you start.
Start to finish, from an empty PC to a game running — with the honest caveats in place.
If the AVX2 or Vulkan requirements are not met, stop here and read the spec page first. Neither can be worked around.
Each step has its own page under setup if you want the detail, but for most machines this list is the whole job.
Pick something light and well-behaved rather than the most demanding thing you own. Kena or Astro Bot will tell you whether your setup is sound in a couple of minutes.
Check the chip before you commit an evening. A title sitting in Test is expected to break, and that is a statement about the emulator rather than about your PC.
Vesper is early software. Crashes and visual glitches happen, statuses move in both directions between builds, and we make no resolution or frame-rate promises anywhere.
What you should get on a machine meeting the recommended spec is a launcher holding 400+ status records, your own library listed with honest chips, and the Stable titles playable for a full evening.
You do not need the console, but you do need the games you intend to play and an official copy of the system software file. Vesper supplies neither.
The Windows installer is free, with no account and no payment. What costs you something is owning the games already.
Usually under an hour, and most of that is firmware copying and the first boot. The steps themselves are quick.
Check that firmware is installed and system software has been booted, since a tile cannot launch without them. If both are fine, look at the title's chip.
