Colony 7 - 2600 vs. Arcade

Hi there!

 

I've spent a lot of time today playing Colony 7 on MAME, regarding a few aspects of the game:

 

- Crosshair and enemy speeds

 

I actually recorded an AVI of me playing the game, moving the crosshair around from top-left to right-bottom, I let the bummer do a full travel from left to right, and then I spent some more time single stepping through the AVI frame by frame and to my suprise, finally coming to the conclusion that the last binary I sent already is a very close match to the Arcade. Just to make sure though, I tried tweaking all speeds some, like doubling the crosshair speed on vertical or horizontal movement, doing the same with the enemy sprites, just to *feel* the difference and, just to backup my MAME measurings, the current speeds seem to feel best.

 

- Bummer behaviour

 

I recorded a full attack cycle AVI of it and it seems pretty simple. It always drops a bomb precisely at the same spot, so that it'll straight knock out your cannons. Should be easy to implement that 1:1. Almost there actually :)

 

- Scout behaviour

 

Uihjah. It took me a long time, but finally I figured out what it actually *does* :twisted:

 

The Arcade has the enemies attacking in waves of say 30 fighters. Whenever you shoot an enemy ship, a counter is decreased until it reaches zero - wave completed.

 

Now, what does the Scout do? Answer: If you don't shoot it quickly it alarms other ships! :-o

So while the Scout is visible on the screen the ships-to-destruct counter slowly increases!

 

Hmhm... of course, I can replicate this behaviour as such in my version easily, only how would I visualize it? There's no room for a ship counter on the screen... :ponder:

 

Greetings,

Hi there!

 

How about a simple thin horizontal line?

 

That is an idea... *checks sourcecode* ... there is in fact one single unused scannline left at the bottom... I'll try that!

 

Another option I thought of myself by now, would be alternating the score display with the shipcount numbers. But a small horizontal line might be better suited.

 

Where should I place the line? Right below the score with sprites, or below the bottom scenery with the PF? I think below the score might be less confusing to the player.

 

Greetings,

Manuel

The only problem with putting it below the score is it might be chopped off on some TVs (depending on how many active scanlines you are using).

 

Another suggestion would be to draw the remaining ships as dots at the top of the screen. (Think of how Tempest does it.) They would flicker, but that wouldn't be too bad.

 

And if you haven't checked, KLOV has the manual for the arcade game, which describes each of the attackers.

I'll check that out, thanks for the suggestion! :)

Uh... oh... I used to have that already. I think I deleted it the first time around, because it looked like a repairs manual only :D

 

But you're absolutely right, on page 4 it has all attackers described :)

 

(Sidenote: In the KLOV I just found infos about a "Nudist Colony" Arcade - from 1936 :))

Wow, that was fun, your comment about pre-video arcade games got me exploring that topic. It has been a favourite of mine, although I rarely spend much time investigating.

 

When I was younger in Vancouver B.C. there was one place downtown that had a pre video game arcade. It was an antique arcade but it still operated and you could play the digger games, the shooting games and other games of skill.

 

Maybe you should have a poll (oh say around April 1st) of which amusement arcade games should be converted to the 2600. :)

 

BTW I found a need link by the guy who made the "Secret Life of Machines" show (which was quite excellent) which has some fun stuff on the older arcade machines.

 

A Short History of Amusement Arcades

 

Actually, April Fools aside doing some of these games on 2600 or other would be a gas.

 

Oh, and check out the mainpage for Under the Pier because it looks interesting in it's own right.
