It is determined by how they go to the brand new platform. There are two predominant methods of doing this – porting the sport undertaking to the brand new platform or emulating the previous recreation on the brand new platform.
Porting the sport mainly means taking the previous code and property and making them run on the brand new {hardware}. This includes getting the previous recreation operating natively (i.e. the sport itself compiles, hyperlinks, and runs) on the Change 2. That is often the selection for newer video games and initiatives – stuff that’s newer often doesn’t depend on out of date instruments or a workflow that’s not supported. Since we will nonetheless use the instruments that the sport was constructed with, we (or some contracting studio) can get it engaged on the brand new {hardware}.
Emulating the sport means constructing a digital machine across the unique recreation that pretends to be the unique {hardware} and modifies the inputs and outputs to and from the sport. Emulation is often performed when the sport growth workflow is not possible – e.g. the sport was constructed with historical instruments on historical {hardware} that’s not supported wherever. As a result of we will’t modify the unique recreation, we have to construct a field round it that we will modify and run the unique recreation inside that field.

The choice on whether or not to port or emulate is often pushed by what’s best and most cost-effective. Porting is often most popular to emulation if out there, as a result of it signifies that the porting staff has entry to instruments, property, and presumably even the unique dev staff to reply questions. Emulation signifies that any gameplay adjustments are typically very troublesome since rebuilding the unique recreation might be unfeasible.
