LEGO City Undercover: The Chase Begins statically recompiled from 3DS into a standalone PC build

GTTeancum's recomp, described as AI assisted, turns LEGO City Undercover: The Chase Begins (3DS, USA) into a standalone PC program using the 3dsrecomp tool and the Zakuro 3DS runtime. The README says 3dsrecomp finds 92.5% of the code, all 10,769 recompiled functions matched the interpreter with 0 mismatches, and the Linux build reaches gameplay in Cherry Tree Hills, with a right-stick camera and the bottom screen shown picture-in-picture. A Windows build cross-compiles but has not been run on Windows. The README is plain that this is recompiled emulation, not a source port: the code runs natively but still works on emulated ARM registers and 3DS memory. There is no prebuilt release.
