Arcade adventure starring Sabre Man (again!)

And now, the moment you've been waiting for ... The Pokes. Well, grab yourself a blank tape and your original copy of Underwurlde and get ready. First off, type in the following special header program.

This hack remains untested, because Ultimate have barred distribution of all their old Spectrum games, so I do not have a tzx file of the original tape image to test it with. I provide a download link so you can download this hack anyway.

100 CLEAR 32000
110 FOR X=32768 TO 32769
120 READ A: POKE X,A
130 NEXT X
140 PRINT "PRESS REC ON TAPE DECK AND PRESS ANY KEY"
150 IF INKEY$="" THEN GOTO 150
160 RANDOMIZE USR 32768
170 DATA 221,33,12,128,17,17,0,175,205,194
180 DATA 4,201,0,175,66,85,83,84,69,82,83,32
190 DATA 32,13,4,0,128,217,3

Run this and Save it onto a blank tape (following the instructions on-screen). Once done, rewind the tape and clear your Spectrum using the command RANDOMIZE USR 0. Now type CLEAR 25000, press Enter, type LOAD "" and start up your tape. When the header's loaded, take out your tape and replace it with the original copy of your Underwurlde tape. Remove the lead from your cassette machine and listen to the tape, pausing it just after the program header (this is the short section that's heard first on the tape). Now reconnect the lead and start the tape up again. When the 'OK' message appears, pause the tape again, and type in the following commands;

POKE 24791,251 : POKE 24792,207
RANDOMIZE USR 24740

You should now get a garbled message on screen - just ignore it. Type NEW, press Enter and type in the following listing.

100 READ N
110 FOR X=62421 TO 62420+N
120 READ Y: POKE X,Y
130 NEXT X
140 RANDOMIZE USR 62374

DO NOT run the above yet, as the final stage is to select one of the following data lines and add it to the above program. Each line does something different but only one can be used at a time!

For infinite lives;

150 DATA 11,62,0,50,240,231,50,244,231,195,
242,103

To stay immortal after finding a gem;

150 DATA 11,62,0,50,153,148,50,154,148,
195,242,103

To make weapons appear in the same places each game;

150 DATA 8,62,0,50,199,232,195,242,103

All you have to do now is type RUN, press Enter and re-start the tape. Good luck!
