#4119814 Moon Patrol - Arcade Sprite Hack (Call for Moon Buggy drivers!)

Posted by doctorclu on Yesterday, 7:38 AM

This is a call for brave volunteers to patrol the lunar surface to protect the citizens against visiting riff raff.

Seen above is a sprite hack of the Atari 800 version ** to something more like the Arcade*, with all background and buggy character color matched to arcade screen shots.

 

The latest rom to try is here (not the same buggy, though that version is being developed, however the colors are the same.) **

 MoonPatrol 02 5200.bin 

 

How you are needed:

At current we are getting conflicting color reports...

... Altirra (Windows under Wine) is the larger image left and the small image to the lower right was taken from Atari800OSX.

 

Can someone please try the above image on real hardware and report your results/screen shots/pictures to the hacking thread?

 

 

 

There are more technical programming questions regarding this that can be found on this programming thread.

A bit puzzled by this.   Woke up, tried alternate video modes on both emulators to try to figure out what was going on.   Tried GTIA and CTIA modes.   Wondered if having this in x2 mode on Atari800 made the difference but both are still different.   I know we'll settle this eventually.

Great job, much better looking :grin: :grin:

 

Yes the Atari800 colors looks close to perfect !  Altirra looks way off.. 

Someone should try it on real hardware.

 

you think you can make the (egg yolk) saucer, more yellow ?

 

Yes, if some Atari 8-bit computer gamer could try this on real hardware will help a lot.   (5200 gamers can try this version to check out the colors for now....)

 

More yellow for the saucers?   I believe it should be in the bank of colors found, so when we nail down which is more hardware accurate (Atari800 or Altirra) we can adjust it all then.

After a weekend of tests we finally caught a glimpse of the emerald hills of the lunar surface!

So looks like the bank of color codes is actually here, the same place where the buggy code was too...

 

Screen Shot 2018-09-23 at 10.06.08 PM.png

 

And so I've color matched all the horizon (even the blue ones in the back) to the arcade look.  :D

 

Screen Shot 2018-09-23 at 10.01.46 PM.png

 

So just add those alien sprites you've been working on, and we'll be even closer to the arcade!

#4119295 Moon Patrol Graphical Improvements in Mind

Posted by doctorclu on Sun Sep 23, 2018 1:22 PM

I've never realized that graphics take up a bunch of space before I've made this rough map of the 16k ROM (not to scale):

Wanted to say your original message has inspired a lot of fun.   You are welcome to join the fun, and make your own moon buggy here.

 

I found the chart you made above very helpful.  How did you figure out those values?

2nd alien ship (egg yolk) closer to the arcade, rotating with 3 frames of animation (just some dots moving)

I stretched it horizontally to be bigger than the red flying saucer, as it should.

I don't like the arcade version but for authenticity I left it in..  I'll try later to incorporate the Atari animation into the arcade shell/shape ;)

 

Check it out  :)

 

Just played this, yellow saucers look more like the arcade.  :D

 

I just wonder if the programmers back in the day had regular access to a Moon Patrol arcade machine?

That is really cool.   English translation from Spanish for those that want to read it:

We also got this comment from the 5200 podcast

Screen Shot 2018-09-23 at 8.40.49 AM.png

 

The whole screen flip happened when I tried a value to raise the body off the wheels.   All the rest of these hacks don't have that occurrence.  :D

 

Trying to find other color values now to make this more like the arcade.  Mainly trying to turn the lower layer from brown to green.

 

ENEMY SHIPS

Love what you are doing there.   You might find it interesting I did the same thing for the 2600 version.   Like here you only have one layer of color and unlike here you had two cells of character animation where here you have three.   And I eventually found a solution for six moving wheels.  Someday we need to hack a second color layer for the buggy into that game so like this version, it can have a pink body and black wheels.

 

So definitely like what you're doing.

Here is the nippy blue buggy, complete with windshield glare :-D

I really like this little guy !

 

Yes, this little guy is quite cute.  :D   I would call it "greasy cricket" but I'm sure you have another name.

 

Screen Shot 2018-09-20 at 6.48.39 PM.png

 

I think you and I might have started a version of "choppers" for Moon Patrol.  We not only changed it from a ugly vehicle (sorry original programmers, you should have lined up that windshield better...) and made a custom chop shop for people to create a whole hot wheels catalog of custom mods.  :D

 

LET THE MODS BEGIN BOYS!!

 

Coming up... THE BATMOBILE!!

 

Seriously though, what would I like to make?  Have to think on that.

 

We need to figure out the color codes and how to change that.  I can change it red, how about other colors?

 

I can raise the wheels a bit, but can we make a stable version?

 

And if we can mod the wheels.  I know the cells beneath the body run so that it is like a moving roll of film.  Can mod that to make other wheels and other effects.

 

I like your insanity on this.  :D

 

And at some point we need to modify the 5200 version.  Those poor people still have an ugly vehicle.  Then again they COULD just hack their own at this point.  :P

That was me last week with Miner.  Especially looking for the color codes.  I would try a hue, look at a variable codes, and say "Ok, this should get it... no?   Ok this will get it..."

 

And I would come up with ideas and want to try them right then.   Why I did not mind pulling a few all nighters at work recently when a colleague  dumped some needed information on me after requesting that for a month and saying "Oh and we needed the final project Friday".   I just smirked.  :P   Feast and famine.

 

So when you get a chance let me try your hack!

#4116825 The 2018 Atari Awards!

Posted by doctorclu on Wed Sep 19, 2018 11:58 AM

Was cool to see myself on the hack list!  :D

 

About Miner 2049er which says this:

"Miner 2049er Faster (Miner 2049er hack) by “doctorclu”"

 

Actually was a product of efforts of Thomas Jentzsch (the speed up hack), OmegaMatrix (reset bug fix), and myself (sprite hack).   I just combined the efforts of all three versions into one.

 

Would like to see more about Battlestar Galactica NEO being a BSG fan.   Be interesting to see what different directions he took the Space Attack hack from the one I did.  Could someone provide a link of where to find it?

 

Shame Bubsy: Kitt'N Kaboodle was mostly done by December 24th (2017) with the Holiday Special.  I did more Fast Eddie hacking in 2018, but that was mainly on the Vic-20, and C=64. 

 

Will be curious if Atari 800 and 5200 hacks make it on the list eventually.
