+# Undertale for the Apple II
+## or rather, an Undertale music/graphics demo for Apple IIe/IIc computers
+The basic idea here is to build software capable of running the UnderTale intro (and a few extra songs) on the Apple IIe/IIc, without any expansion cards or extra memory!
+
+There are four files here:
+* this readme;
+* a PDF with some barely annotated 6502 assembly source code for selected routines;
+* UnderTale.do, which is the DOS-ordered sector image for side A of the diskette;
+* and UnderTale jukebox.do, which is the image for side B.
+
+To try it for yourself, transfer both sides to a diskette using ADTPro or similar software. Insert side A and start up your Apple II, which should then boot into Beagle Bros' Pronto-DOS and automatically move DOS up in memory. Then, RUN UnderTale. (RUN IT BY LEGAL to view some legally advisable acknowledgements.)
+
+There is a JUKEBOX program on side B, which should not depend on anything in the UnderTale program. However, you must boot from side A and then turn to side B, or the JUKEBOX program will break down due to DOS not being where the JUKEBOX expects it to be (i.e. not in its way).
+
+UnderTale belongs, of course, now and forever to Toby Fox; Temmie drew the prologue artwork. Said artwork was colour-reduced and dithered in the GIMP, reprocessed via a custom Python script to fit the hi-res page, and compressed using faddenSoft's fhpack. The production made heavy use of CiderPress and Virtual ][, which are both excellent pieces of software.
