> I can’t use ctrl+C in the terminal for Copy because that’s reserved for the interrupt signal.

It's not reserved - the terminal emulator is free to handle any key, in any way, however it wants. Some examples:

1. The XFCE terminal allows you to specify whether Alt+[X] means Meta-[X], or whether it should trigger a menu shortcut.

2. macOS's Terminal.app: use System Settings to rebind Copy to Ctrl-C - when some text is selected, it copies that text; when there is no selection, it passes the ^C along.

Unfortunately, few people question the status quo of terminal emulator design. Look at all the other emulators around you: quick save/load, customisable hotkeys (including gamepads), speed up/slow down, mute specific audio channels, enable/disable sprite/layer rendering, peek/poke memory, and so on. An average GBA or SNES emulator gives you better tools than most terminal emulators, and the latter are what is actually being used to get work done.
