Feasible but High Complexity . Requires a Wine/Box86/Box64 translation layer rather than a native reimplementation. Performance on RK3566 devices will be marginal; recommended only for RK3588 and x86-based handhelds.
A Diablo II PortMaster port is but requires careful management of expectations. It will not be a native ARM port; instead, it leverages Wine + Box86. On higher-end handhelds (T618, SD845, RK3588), the experience can be very good (35–50 FPS). On budget RK3326/RK3566 devices, performance is likely unacceptable. diablo 2 portmaster
