So she wrote a shim. A tiny ARM64 service that hooked the emulator’s memory mapping, trapped the self-modifying write, and redirected it to a clean, non-self-referential code cave she allocated in the x86 process’s address space. It was ugly. It was hacky. It worked.
For six months, it worked like magic. The little ARM chip would trap x86 instructions, translate them on the fly into ARM64, and execute them. The user never knew. The app never knew. It was a ghost in the machine. windows 10 arm 32 bits
Every second, the emulator was logging the same error: “Translation block exhausted. Recursive indirect branch detected. Fallback to interpreter.” And then, a second later: “Interpreter timeout. Resuming translation at address 0x7C42A1F0.” Over and over. A loop. But not a crash—a hesitation . The emulator was translating the same dozen x86 instructions, failing, falling back to a slow interpreter, timing out, and retrying. Each cycle took about 15 milliseconds. So she wrote a shim
