Important: Line 4 use syntax exclusively from Japanese Smilebasic. To play this game you should comment that line and add XSCREEN 3,512,4 after it.

BIG stills has features that the 3DS version doesn't. The only thing 3.5.2 does is to ensure programs written to run in 3DS mode for BIG don't fail on the 3DS version. WIIU mode programs still have exclusive features not supported by the 3DS version.
EDIT: in the case of this game specifically it no longer requires a patch to work.
