+description = "A libretro port of yaps2, a PlayStation 2 emulator forked from PCSX2 and aimed at ARM handhelds (working arm64 recompilers, Adreno fixes). The core renders through the frontend's own Vulkan context -- it takes the VkInstance and VkPhysicalDevice from the hardware-render context-negotiation interface and hands finished frames back through set_image -- so a Vulkan-capable driver is required and no other video driver will work. Place a PS2 BIOS dump in 'system/pcsx2/bios' and a copy of the emulator's 'resources' directory in 'system/pcsx2/resources'. Save states, .m3u disc swapping and the usual renderer/upscale/speedhack core options are implemented. This core is experimental."
