Set the frameskip option to 1 or Auto . This allows the emulator to skip rendering certain frames to keep the game logic running at full speed.
For years, the idea of playing Sega Saturn games on the PlayStation Vita was a pipe dream. The Saturn’s notoriously complex dual-CPU architecture made it a nightmare to emulate, even on powerful hardware. The PS Vita, with its modest ARM Cortex-A9 core and 512MB of RAM, seemed out of the question.

For years, the PS Vita struggled with the complex architecture of the Sega Saturn. While it handled the SNES and even some N64 titles with grace, the dual-CPU setup of the Saturn caused headaches. This new update, however, focuses heavily on optimization and compatibility, turning "playable" into "enjoyable."

Synchronizing all of these components simultaneously requires immense processing power. Even modern PCs struggled with Saturn emulation for over a decade. The PS Vita, while a powerhouse of its generation with its quad-core ARM Cortex-A9 processor, faces a massive uphill battle when translating the Saturn's multi-chip architecture into efficient software instructions.
A very old Yabause port for the PSP can be run via Adrenaline on the Vita, but it is limited to a single title— Panzer Dragoon —and even then, it runs at a significantly reduced frame rate. Better Alternatives for Portable Saturn Play

However, the homebrew community has made surprising breakthroughs using optimized retro-arch cores and standalone emulators based on (formerly Yause) and Yabause . Recent performance updates focus heavily on dynamic recompilation (dynarec) and Utilizing the Vita's GPU via hardware acceleration to offload work from the strained CPU. Recent Updates and Performance Breakthroughs
The simple hardware reality is that the PS Vita lacks the raw power to handle Saturn emulation. In community tests, the Saturn cores available via RetroArch on the PS Vita run at speeds of approximately , which is a proof-of-concept rather than a playable experience. Other users on forums like GBAtemp have reported that even the dedicated Yabause port hovers between a slideshow-like 5 to 20 FPS .
