My solution was to use a decade old, obscure, Korean fork of DOSBox called DOSBox Daum, which works exactly the way I need it to. It does advertise a native Linux release, but as a total noob to the ecosystem I have no idea how to actually install it since it was only ever released on the creator's website as a standalone download.

Now that is a first... I assume that the DOSBox-X build you used was linked to SDL1? It is a real old library (like, back in the 9x days) that was only "maintained" via a compatibility layer with SDL2 (that is now also under maintenance since the release of SDL3) and thus are not behaving well with the current Wayland ecosystem of modern Linux.
As for the Daum fork you mentioned, unlike Windows, program libraries are not compatible between updates, it is unlikely that you could run it into your current Linux install without figuring out the exact versions of libraries that the program needs. (Also, it is a bad idea in general for a software developer to self publish their programs on Linux as each distros has its own tweaks that only its maintainers could know.)
