Build a rom for orix

Clone this repo : https://github.com/orix-software/empty-rom

parse_routine:
; A & Y contains the string to execute
; for example, if you want to execute the program hello in your rom :
; exec hello
; exec command will call your “parse_routine” with “hello” string pointer in A & Y
; BUFEDT contains your command without exec word
; if you want to call any program in your rom, you can do :
; lda #<mystring_to_execute ; mystring_to_execute must be in ram because rom which contains the command needs to access this string in order execute it
; lda #>mystring_to_execute
; BRK_ORIX($63)
