Software:Use a software page table for address translation. Highest accuracy but slowest performance.
Host(fast):Directly map memory in the host address space. Much faster JIT compilation and execution.
Host Unchecked(fastest, unsafe):Directly map memory, but do not mask the address within the guest address space before access. Faster, but at the cost of safety. The guest application can access memory from anywhere in Ryujinx, so only run programs you trust with this mode.
