Xcom1 is DOS-only rip outdated version here (no windows version provided). DosBox is fully copatible. Ofc as emulator it always should be tweaked manually for each game on rach pecifi machine.
Probably download updated dosbox files from of.site.
Xcom2 officially come here again as rip - but in truth its full latest version. Wiht windows (up to date) and win_updated.exe files. Those exe is not prefectly compatible, but GOG offline launchers or Galaxy by default use DosBox emulator and DOS exe file.
There is gameplay bugs still present for DOS versions, thats why windows and win_updated.exe are better. But DOS easier to emulate on Win8\10\11. For Win7 still better use win_updated exe.
