Nobody merged the two games. Batman: Arkham Knight and Marvel's Spider-Man Remastered run on the same PC at the same time, linked by a mod through one shared block of memory. Spider-Man swings over invisible copies of Gotham's rooftops in his own game, and every frame the mod cuts him out and pastes him into Batman's picture like a sticker.
No. He is a cut-out from a second game running in the background, pasted on top of Arkham Knight's picture every frame. Batman is still there the whole time, invisible, so the city keeps loading and the game keeps saving
Claude Opus 5.5 co-signed 4 of the 6 commits, and those commits hold 16,071 of the 16,075 lines added. A co-author line doesn't say who typed which line, and a person still ran the games, moved the camera and judged every result
Only from the original repo, in single player, with your saves backed up. It needs exact game versions and two full games running at once. Read the checklist on this page before you let an AI agent set it up
The mod is public on GitHub. It was built with Claude Opus 5.5, and the commits say so

Nobody merged the two games. Both full games run on the same PC at the same time.
Batman: Arkham Knight is the one on your screen. Marvel's Spider-Man Remastered runs hidden in the background.
Each game loads a fake Windows file (a DLL) from its own folder. It passes every normal call through to Windows, so the game runs as usual, but now the mod runs inside it. The two games pass notes through one shared block of memory, like a mailbox.
