This code only works on the arcade system, not the home consoles, because only the arcade system has a built-in system clock. which can be read using <code>JSR $C0045C</code>. MAME uses your computer's date and time as the source for this data. The code below runs in-line and uses a few macros and labels, but they are mostly self-explanatory. The code required to set up the palettes and print characters to the screen has been omitted for brevity, but is fully implemented.

===Idiomatic===
This restores the legitimate code which has twice now been deleted by the poster of the hacks below. Explicitly: square brackets are not and have never been part of the AppleScript language and <tt>«class isot» as string</tt> is a hack someone discovered many years ago when it wasn't possible to coerce AppleScript month enums directly to integer and when AppleScript's <tt>string</tt> class used 8-bit characters. Back then, the coercion from <tt>string</tt> to <tt>«class isot»</tt> also worked. But this ended with the introduction of AppleScript 2.0 in 2007, when <tt>string</tt>, <tt>Unicode text</tt>, and <tt>text</tt> became synonymous terms for UTF-16 text. The ability to coerce from 8-bit text specifically to <tt>string</tt> was retained for compatibility with existing scripts and for reading non-Unicode text files. Other classes of text such <tt>C string</tt> were discontinued.
Whether or not they happen to work, to insist on posting code containing things which have never been part of the language without noting them as hacks, when they're entirely unnecessary, and deleting legitimate and effective code to make way for them, is seriously to misinform readers.
<syntaxhighlight lang="applescript">set {year:y, month:m, day:d, weekday:w} to (current date)

===Hack alternative===
AppleScript <code>date</code> objects are very simple to manipulate, provided one is familiar with the slightly unintuitive nature of how they should be handled in order to be robust and produce the desired result across all systems. Despite the official documentation claiming otherwise, AppleScript is not able to parse date strings that don’t strictly adhere to the date and time format strings specified in System Preferences—thus it is a setting that is specific to one’s system, and won’t naturally port. <br/> <br/>
AppleScript provides properties and classes specifically for manipulating or constructing date objects that are not dependent on anything outwith the AppleScript language. In most cases, the <code>current date</code> command provides a starting point, from which one gets current or sets new values for its <code>day</code>, <code>month</code>, <code>year</code>, and <code>time</code> properties and property classes to determine or affect the date a particular date object refers to. <br/> <br/>
Formatting is usually achieved by extracting individual date components, performing text manipulations (e.g. to prepend leading zeroes) on each of these, then concatenating these for the final result. The <code>«class isot»</code> class doesn’t have a vernacular form and can only be accessed using its raw chevron syntactic form, which others may recognise from similar AppleScript classes such as <code>«class furl»</code>, <code>«class utf8»</code> and so forth. They can provide some useful—and, often, more reliable—features that can save the headache suffered by many when learning how the <code>file</code>, <code>POSIX file</code>, and <code>alias</code> classes differ between one another, and then also with the way the same class can be implemented in ways or yield unexpected results when used in a context specific to a scriptable application. <br/> <br/>
<code>«class isot»</code> and <code>date</code> class objects can coerce to and from one another. The <code>«class isot»</code> is an opaque data type wrapping the hexbytes of an ISO-8601 formatted datetime string. Sadly, it doesn’t permit one to use it to convert a string into hexbytes, but it is ideal for taking a <code>date</code> reference via the <code>«class isot»</code> intermediary form and coercing this to <code>string</code> class (whose chevron syntax form is <code>«class TEXT»</code>), but it will '''not''' coerce onto other AppleScript classes that are normally used interchangeably to represent strings, namely <code>text</code> (<code>«class ctxt»</code>) or <code>unicode text</code> (<code>«class utxt»</code>). <br/> <br/>
Both scripts provided below, contributed separately by different users, each make use of the features discussed above. The first demonstrates the simplest and most direct solution, but simplicity forces specificity, which limits what other algorithmic problems it could usefully or easily be adapted to solve. The latter borrows a functional approach and favours an initial investment to create the atomic handlers that pay off by providing the reusable building blocks of identical code that will be the composable functions all other scripts are assembled from sparing much of the need to write new code to solve the vast majority of problems on this site. Generality, versatility and adaptability of this approach can be proven mathematically. <br/> <br/>

=== Version 2: Meta Language ===
Forth is less of a language and more of an extensible toolkit of simple routines. This version attempts to demonstrate using the simple routines to extend Forth. Then using the language extensions and the power of concatenative language to solve the problem. This solution could create numerous date formats as one line definitions now that we have our "date" words defined. Typically these extensions would be saved as a library file.

Module racket/date is included within #lang racket
However its date to string facilities only provide ISO-8601
(which provides the "2007-11-10" format) but nothing
that strictly provides "<Full day name>, <Full month name> ...".
We therefore need to import SRFI/19 "SRFI 19: Time Data Types and Procedures"
(it's a standard Racket package).
See: http://srfi.schemers.org/srfi-19/srfi-19.html
<syntaxhighlight lang="racket">#lang racket
(require srfi/19)
;;; The first required format is an ISO-8601 year-month-day format, predefined
;;; as ~1 in date->string
(displayln (date->string (current-date) "~1"))
;;; You should be able to see how each of the components of the following format string
;;; work...
;;; ~d is zero padded day of month:
(displayln (date->string (current-date) "~A, ~B ~d, ~Y"))
;;; ~e is space padded day of month:
(displayln (date->string (current-date) "~A, ~B ~e, ~Y"))</syntaxhighlight>
both ~d and ~e satisfy the format required, since the "10" part of that date is 2-digit
