On the topic of emulating old hardware, this reminds me of the Nintendo 64 VRU accessory, which is a mic + voice recognition that was used in games such as Hey You Pikachu. Nobody has emulated the hardware which performed the actual voice recognition, instead opting for modern VR libraries. So while you can use it in an emulator, the performed VR won't match what you'd get with the limited hardware implementation.
>This is an HLE implementation. I did not emulate the manner in which the VRU does voice recognition
