I've been meaning to exercise myself to be sure to master the concepts depicted in Ersanio's SNES general asm book.
In order to do so, I would like to know whether I can test small lines of code without having to insert them into SMW?
If such an "assembler" or "executioner" exists, I would be able to access addresses, try some LDA/STA; debug some branching, etc.
Actually I have found this page
and this other one
full of ASM assemblers (direct access ctrl+F 65816), but I'm not too sure which one does that. Or maybe I could just try and execute code in asar?
Thanks in advance.
