Some developers have ported simpler emulators (GameBoy, NES, even PS1) to WASM. PS3? Likely , if ever.
WebAssembly now includes SIMD (Single Instruction, Multiple Data) instructions – 128-bit vector operations that map beautifully to the PS3’s SPE vector units. Early benchmarks show that WASM SIMD can be 2–3x faster than scalar WASM for certain workloads. But it is still slower than native x86 SIMD (AVX2) by a factor of 2–4x. ps3 emulator on browser
For the best experience, desktop software is the industry standard: Some developers have ported simpler emulators (GameBoy, NES,
