Need for Speed Underground 2 now runs directly on Nintendo Switch — other Classic Windows titles playable thanks to custom firmware boot

Retro gaming fans who own Nintendo Switch consoles now have several classic Windows titles they can now enjoy. A video shared on Twitter/X shows the well-loved Need for Speed Underground 2 running pretty smoothly on Nintendo’s hybrid device. Meanwhile, a forum about Wine-NX says that Quake III and OpenTTD are also playable, with WarCraft III nearly ready, too. It's early days for this 'experimental' software, but things look very promising.

In the embedded video you can see NFSU2 runs rather well on Nintendo’s hardware. Older PC games are perhaps a good fit for what many consider to be the rather anemic specs of the Switch. A status panel shows CPU and GPU usage. According to the forum post “Races run at roughly 20–45 fps at default detail with the CPU overclocked.”

Other games that Wine-NX can handle well at this time include OpenTTD (Transport Tycoon Deluxe), which runs at up to 60 fps. Quake III Arena is also capable of running at around 37 fps at 1,280 x 720 pixels, according to the source. The last PC game mentioned as being compatible, almost, is WarCraft III, and specifically this work in progress has working “menus, campaigns, and now cutscenes.”

The Wine-NX forum page linked to helpfully explains what exactly this is, and how it works. In brief, Wine-NX is a port of Wine 11 to the Switch’s native Horizon OS. It comes as a homebrew package in the NRO format Horizon expects games to be in, but that allows it to run Windows programs and games with Box64's ARM64 dynarec translating the x86 code. Graphics are handled through Mesa 20.1's nouveau driver. It supports audio and touchscreen, and the Switch controllers can also handle mouse / keyboard duties – as well as doubling as an Xbox 360 controller.

You can’t use any Nintendo Switch to load Wine-NX and Windows PC games. You’ll need to have a console that can boost custom firmware, and run homebrew NROs. That means an older unpatched Switch or one with a hardware mod.
