A shader the recompiler cannot translate is a gap in emulation, not a reason to take the process down: skipping the draw or dispatch that wanted it costs some rendering, while aborting costs the title. CompileOptions gains non_fatal and CompileResult gains unsupported. With non_fatal set, the three places the recompile path gives up - an opcode with no IR translation, a CFG that will not build, and resource tracking that cannot resolve a descriptor - record the failure and unwind rather than calling EXIT, and Recompile returns a result marked unsupported. The caller skips that draw or dispatch. Nothing changes when non_fatal is clear. Marvel's Spider-Man: Miles Morales meets an untranslatable compute shader on its third frame, so a strict build cannot pass the opening logo. Astro's Playroom is also stopped by a shader today and reaches a later, different failure with this in place.
