Games can be patched to work on lower system versions, yes. However, eventually, this will not be sufficient in getting games to work on SX OS and 11.0.0. There are three types of system version requirements:
- Soft version requirements, which can be patched easily
- Encryption keys, which can be patched
- Software development kit version requirements, which cannot be bypassed, since the game will require assets on newer system versions.
In other words, newer games that require assets in 11.0.1 and higher (or more likely, 12.0.0 and higher) will not be able to be patched to work with SX OS. My understanding is Mario Golf is patchable, however.
