BG COPY 0,0,32,16 TO 0,0
The most i can do is 32. when i try to do 64, 96, or 128, it gives me a “Invalid Parameter” error

The memory reserved for tilemaps only allow a 32x32 map size, even if you can make larger BG files. If you want to access tiles 'further inside' the map, you can modify the first two arguments, being start x and y.
Let's say you make two full screens in a single map in the GFX editor, and you want to show the second. That would place the second screen at 32, 0 in the map. The code to copy that second map would be BG COPY 32,0, 32,32 TO 0,0.
I urge you to thoroughly read the manual page for any function you use, if you are unsure of how it works.

@wryhode the Lowres NX manual is mostly sparse and. only has a sentence or 2 for any function.
