Looking to convert an old PC into a retro gaming machine
You're looking to run RetroPie on a PC by using a 20GB hard drive as storage. The idea is to install Raspbian first, then add RetroPie on top. You want the hard drive to hold ROMs and system files instead of relying on an SD card like the Raspberry Pi does. This approach can work but requires careful setup. There are guides available online that walk through partitioning the drive, installing the OS, and mounting the necessary directories for RetroPie. Make sure you back up important data before proceeding.
Raspberry Pi uses ARM architecture while your old PC is based on x86. They aren't directly compatible, so you'd need tools like QEMU to emulate x86 and run Retropie or Raspbian in a VM. Using Retropie in such a setup is probably not feasible.
Most Raspberry Pi OS versions are designed for ARM processors; if yours isn’t ARM-based, it’s unlikely to run smoothly. You could try compiling the software yourself using the source code from RetroPi or Piplay for your specific architecture, though success isn’t guaranteed. The safest option is likely purchasing a dedicated Pi to run RetroPi/Piplay directly, or installing emulators on your computer instead.
