[WIP] Moon Patrol conversion
 
Just a small video to show how buggy it is ATM but at the same time the colors are okay, and there's the double mountain parallax (no dual playfield)

This is going to run on 1MB ECS amiga

You'll notice the ugly color bars on the sides. If someone has an idea how to hide them? I"m changing color 0 so I don't have to blit some empty space after the mountain layers, but it has this nasty effect.

You'll also notice that the ground is not scrolling, and the buggy wheels are all in sync. This will of course be fixed soon.

Id love the see an enhanced moon patrol port for the Amiga

can you change the floor color to white or light gray like in the real moon?
I think it would look fantastic and more realist
also a photo of half the earth in the sky as it really looks on the moon

I was watching Pints and Amiga just today and Jack was coincidentally asking about a Moon Patrol port, it really made his day when he discovered this.

For color bars at the side I would suggest:

- ECS Border Blank, since you've got ECS as a minimum requirement anyway (this *can* look a bit weird on real monitors since the border area becomes darker than inner areas with color #000, especially if you've got multiple copper lists)

OR

- Copper list trick. Wait for left edge, set color 0 to your color, wait for right edge, set color 0 to black, repeat for every line (Scorpion Engine does this)

nope I just thinking about an enhanced Amiga port with real moon colors
the pic I uploaded was as example about how it could look like, I did it in 10 mins
the floor of the moon can be enhanced with magicwb patterns or so

btw, I never liked the phantasy ugly colors they inserted in the original arcade, it doesn't fit with the moon

Nice! I used to play this in the arcades. Great fun :)

Excellent new port. The game used to be quite popular back in 1980 and even in the early 1990-ies.
I think best is first to do a proper as close as do original native port, then skins and other enhancements will be very easy.
The game has many ports. I think Atari ST port will be very easy as well, or even easier, since it uses 68000 CPU.
Here is the Atari ST port completed by me:

Other (not complete list) of ports of the game:
Apple II
https://youtu.be/Bqh9UEtOV2Q
Atari 2600
https://youtu.be/8SNjkwb1w_M
IBM PC
https://youtu.be/U8qpemiKetY
Nintendo GameBoy
https://youtu.be/nZSQVxDuDlg
Nintendo GameBoy Color
https://youtu.be/6DMDfpDOVG4
Sinclair ZX Spectrum
https://youtu.be/0O5pn8likxg
Commodore 64
https://youtu.be/xHAE-5NB3rY
Atari 800
https://youtu.be/_mESUbgU_Pg
Coleco Vision (remake)
https://youtu.be/A4YHCWPcdAo
Sord M5
https://youtu.be/vfmIjfnsfm4

There were also some Oric and even Amiga remakes, of which I don't remember the names, but for Oric, Super Jeep is very close:

Here are some playthroughs of the different arcade versions by me:

https://youtu.be/997vZFRE7lk

Would love to play another version of this hit classic arcade game!

Nice! Love Moon Patrol

DanyPPC 07 January 2024 07:45

WoW, this is one of my favourite arcade games of '80s togheter Phoenix, Time Pilot and Ghosts'n Goblins :)

kremiso 07 January 2024 09:30

lovely idea!
i was pretty good with the arcade bitd
yet some coins were missing from my pockets everyday :)

@jotd, i prefer the original mostly pink/green/brown palette

>nostalgia<

jotd 07 January 2024 09:39

Nice mockup but IMHO if you convert everything into gray you get a B & W game. Adding the earth is a good idea but it will consume a lot of colors that I don't have in the 16 color display.

Those games are colored for a reason: attract the player. If they want B/W they just watch Buster Keaton :)

I remember Oric super jeep. Nice effort, big hit at the time. Most of those ports lack the slopes for instance. Gameboy versions are great (except that the music is out of tune! they missed the easiest part...)

kremiso 07 January 2024 11:10

and please give it a boost at the shoots/explosions sfx :)

jotd 07 January 2024 11:15

that's not going to be too difficult as the AY-8192 is really crap at noise.

My min req is not ECS but OCS (1MB RAM, but 512k chip). How would it behave on OCS? If it does nothing, then why not, at least for the first releases.

Yes, but I don't want to set all colors of the rest of the lines. I could but I'll see if I have no other option. After all it may be not as hard as it seems, as I already have dynamic per line color change in my copperlist.

Prosonic 07 January 2024 15:45

this and mr do are needed for amiga or gyrus

Nope... original color scheme or nothing.

From memory it does indeed just "do nothing" on OCS, doesn't break anything but doesn't hide the copper bars at the sides.

That's fair. Good luck, I'm definitely curious to see what you do in the end :great
