DOSBox Staging is a favourite of mine to follow that expands on the original DOSBox but with a focus on implementing new features and fixes. A new major update went out in December 2022 with some big additions. It's supposed to be a drop-in replacement for the old original DOSBox.
Release 0.80.0 and the follow-up bug-fix 0.80.1 adds in support for ReelMagic, an MPEG playback board and so DOS games that depended on it will now work in DOSBox Staging. However, they suggest only enabling it when needed. Eventually they will also be adding in DMA support too.
They also added in dual-mouse gaming so that multiple physical mice attached can be mapped to emulated mouse interfaces, allowing two-player split-screen gaming like found in The Settlers and The Settlers II amongst other games.
On top of that some helper text was added like telling you how the mouse can be captured and released from DOSBox, more settings work properly while a game is running like video resolution, OpenGL shaders, audio devices and others. There's also some additional OpenGL shaders included, plus some bug fixes.
