Can I record binaries from any emulator with Basic commands, machine code, macros or something?

Hello

I do not know if this is the right place to put this question

Normally with ZXSpin if I want to save a binary file, I'm going to: file -> save binary file

I give him the data of memory address and number of bytes and he records a file with the extension
that wants that it can be .bin for example

Buuut ...

Can you do this with some emulator and machine +2, +3, or another, etc
directly from commands in basic or from machine code, that is not in a TAP and are different files?

In pseudocode it looked something like this:

records the first piece of memory in a binary file

record The second piece of memory in a different binary file

etc etc

Maybe there is some macro or something???

More than anything not to do it by hand since they are many :)

That is to say that it is recorded directly to PC from the emulator as different binary files

I hope to have explained myself well :)


Thank you
