Cutscenes

It mostly depends on the style of cutscene you want to create. The easiest option is to use this UberASM to treat a sublevel as a cutscene, which you then just use ExGFX to change the appearance of. For the text, just use an ExGFX file with the letters that you then turn into text via Map16 (see this ExGFX for an example). You can either create the text directly through Map16, or create singular blocks for each letter that you then combine Layer 1 and Layer 2 to write out the text (e.g. every odd letter is Layer 1, every even letter is Layer 2).

Another option is Romi's VWF cutscene tool (demo here). It's a bit more complicated to set up if you're new to ROM hacking, but once you learn how to use it it allows for doing a lot more fancy cutscenes with little programming experience.

Speaking of VWF, the VWF Dialogues patch is a similar option that gives you a lot more control over the visuals (and can be used in other contexts as well), though it's also a lot more complex to work with if you don't have much programming experience.
