Hola carlos! bienvenido al foro de Xbox!
mira revisando tu pregunta lo que pasa es lo siguiente, la version que es retrocompatible con Xbox One (Normal,S o X) es la version de Xbox 360. No la version del Xbox (Original).
Entonces si quieres jugarlo tendrás que adquirir la version de 360 para poderlo jugarlo en tu Xbox One X!
Si no puedes adquirir la version física (es complicado) no te preocupes, puedes comprarlo en version Digital en la Store de Microsoft!
Aquí te dejo el link GTA San Andreas (xbox 360):

Then if you want to play it you will have to buy the version of 360 to be able to play it on your Xbox One X!
If you can not buy the physical version (it is complicated) do not worry, you can buy it in Digital version in the Store of Microsoft!
