than to faff about with POKEs and copying a block of memory from one
TAP file to another.
So here is the patch to make the Bug-Byte edition of Manic Miner
make the Jet Set Willy item-collection sound:

1. create the variant;
2. use SPECSAISIE Compare to determine the differences between the
master version and the variant, i.e. the POKEs that need to be
applied to the master version to generate the variant;
3. edit the BASIC loader to apply these POKEs.
Example:
150 INK 7: PRINT '"If you are liable to be offendedby sexual
graphics, please press"; FLASH 1;"A"; FLASH 0;" to airbrush them
out."
160 PRINT #0;AT 1,5; FLASH 1;"PRESS ANY KEY TO START"
170 LET a$=INKEY$: IF a$="" THEN GO TO 170
180 IF a$="a" OR a$="A" THEN GO SUB 240
190 RANDOMIZE USR 33792
200:
210 REM ***
220 REM * AIRBRUSHING *
230 REM ***
240 PRINT AT
11,0;"Airbrushing
";#0;AT 1,5;" "
250 FOR a=52880 TO 52911: POKE a,255: NEXT a: PRINT AT 11,11;".":
REM Room 7 portal
260 FOR a=53056 TO 53119: POKE a,PEEK (a-64): NEXT a: PRINT AT
11,12;".": REM Room 7 falling Kong Beast
270 FOR a=58000 TO 58031: POKE a,0: NEXT a: PRINT AT 11,13;".": REM
Room 12 portal
280 FOR a=61967 TO 61982: POKE a,32: NEXT a: REM Room 16 name
290 PRINT AT 11,0;"Airbrushed version"
300 PRINT #0;AT 1,5; FLASH 1;"PRESS ANY KEY TO START"
310 PAUSE 0
320 RETURN
In this example, I used FOR-loops to blank out whole sprites, or to
copy a block of data (Line 260), rather than individual POKEs. As a
matter of fact, I manually calculated the addresses which needed to
be changed, rather than using SPECSAISIE Compare.
Let's say you wanted a game to vary in n ways, e.g. an easy variant,
a variant for alternate colours, a clean variant, and a perpetual-
motion variant (n=4). This means 2^n (2^4 = 16) possible variants,
but by incorporating the changes into the loader, you only need to
release one version.
If one variant has too many changes to be hassling with POKEs in the
loader, then it's justified to release both variants as separate TAP
files (as is the case with Expert Mode and Easy Mode). But minor
variants should be coded into the loader.

extra two pixel-rows of fire above the cell itself. So if you have
an Earth-cell horizontally adjacent to a Fire-cell, it can't block
you colliding from above with the Fire-cell.
Technically, there's a little subroutine that is called six times
every time-frame: for each of the four cells Willy is currently in,
and for the two cells directly beneath him (during a jump or fall,
Willy is most of the time in all six cells at once).
This subroutine first checks whether the cell is Air: if it is, it
sets its INK-colour to 7 (white) - unless it's one of the cells
under Willy's feet when he's occupying only four cells.
Then it checks whether the cell is Fire, and kills you if it is.
I've already disassembled this part of the subroutine in Message
5326 (re. harmless Fire).
So, you see, this subroutine is called for the two cells under
Willy's feet, but not for the cells above his head.

like they do in Jet Set Willy (see Message 4620 for more of these
POKEs).
I plan to write a trainer-game myself at some point in the future.
I'll make it JSW64, as that now covers almost all MM/JSW features -
the notable exception being what happens when you walk off the edges
of the screen in MM (although even *that* should be patch-
vectorable).
