What NFK98 means is that the specs you mentioned can't run the latest dev builds because you're running Windows 10 32-bit. We dropped support for 32-bit builds some time after 4.0.2 because 64-bit builds are way faster running on the same system (and also it was holding development back)
Also, Intel G45/G43 express chipsets are so old they lack hardware level functions needed to run Dolphin. Also, at that old of chipset, you're running like a Core 2 Duo (or something similar), correct? At a clock-speed of 1.6 Ghz, I'm surprised you managed to get anything to run at all. Your hardware no longer meats the minimum requirements for Dolphin.
On top of having slow hardware, the Rouge Squadron games require proper MMU emulation to play properly, which is only available in the latest dev builds. And even on supported hardware, MMU emulation is some of the most CPU intensive parts of Dolphin's code, so you need some really strong hardware to run it.
