Penetrator key hack - fire and right separate

Post by R-Tape » Fri Jul 13, 2018 10:13 am

Penetrator is an incredibly playable game - IF you remove having the same key for fire and right. It's probably worth giving it a thread so there's a place for adaptations.

Here's a snapshot (128k for some reason).

And this is the patch, assemble or POKE these bytes at the following addresses:

Code: Select all

org 65535
	db	0
org 35813
	db	3,195,0,252
org 64512
	db	55,62,223,219,254,203,71,32,2
	db	203,192,203,79,32,2,203,232
	db	62,253,219,254,230,1,32,2
	db	203,224,62,251,219,254,230,1
	db	32,2,203,216,62,127,219,254
	db	203,71,32,2,203,208,203,71	;At the end of this row 71=Space key, 81=M key
	db	32,2,203,200,195,27,140

EDIT - can't remember who should be credited for this patch.

Cheers, that makes the game a lot more playable. Just that pesky level 3 needing a edit, that's why they included the editor.
The final bombing run can be a pain, but it makes skill.
Sodding siren noise.

... If you're feeling lazy, laser auto fire:

Code: Select all

POKE 35942,203
POKE 35943,200
POKE 35944,0
POKE 35945,0
I'm not very good at POKEs, but it seems to work.

It would be cool to see someone release a new edit of penetrator (has that ever happened?)

Even better if it also had some revamped graphics. I tried to change the player ship once but it wasn't so simple - there's a collision mask somewhere in the code that didn't like it.

I quite like the siren noise. The first time.

The fireworks? I don't know why in your version they are monochrome. The GIF is from the Timex version, but AFAIK the 48k version also has colors. :?:

Excellent fix, great job R-Tape.
Penetrator is one of my favorite games and is now even more playable.
Here's the original tzx file with the fix applied.
Enjoy. :)
