Um, because of the graphics chip?

So. Z80 can handle hundreds of sprites on-screen simultaneously if a graphics chip supports it.

 

Ok.

Do you guys think a machine like the C64 or Atari 800 could handle Zanac-EX?

It has very fast paced gameplay, AI, fast music, hundreds of sprites on-screen simultaneously, etc...

Because Z80 can handle hundreds of sprites on-screen simultaneously?

 

Why does Colecovision only support 32 sprites on-screen?

I do the sprites like so in CV Sprite 2.  Left sprite 2 is over sprite 3, right is sprite 3 over 2.  Any pixel matches the 1st and 2nd sprite will be the middle color, "3rd color". 

void RotationSprites(void){

if(flicker==0){
i=0;
for(ID=0;ID!=7;ID++){
sprites[2+i].x=objectx[ID];
sprites[2+i].y=objecty[ID];
sprites[2+i].pattern=objectp[ID];
sprites[2+i].colour=objectc1[ID];
sprites[3+i].x=objectx[ID];
sprites[3+i].y=objecty[ID];
sprites[3+i].pattern=objectp[ID]+4;
sprites[3+i].colour=objectc2[ID];
i+=2;
}

flicker=1;
goto flick;}


if(flicker==1){
i=0;
for(ID=0;ID!=7;ID++){
sprites[3+i].x=objectx[ID];
sprites[3+i].y=objecty[ID];
sprites[3+i].pattern=objectp[ID];
sprites[3+i].colour=objectc1[ID];
sprites[2+i].x=objectx[ID];
sprites[2+i].y=objecty[ID];
sprites[2+i].pattern=objectp[ID]+4;
sprites[2+i].colour=objectc2[ID];
i+=2;
}

flicker=0;
goto flick;
}
flick:
}

This is a rolled up loop of 7 objects, omitting the hero and arrow and the flicker 2 and 3 cases.  You can see in flicker==0 that the sprite[2] is over sprite[3]. then jumping over the flicker 1.  Then next delay(1); flicker==1 get taken. Now sprite[3] is over sprite[2].   Doing this will also takes up a lot of sprite slots too.  So each sprite table are loaded per room since there's always 1 monster and 1 treasure per room.  Like treasure chest and skeleton will only load in room 3, Apple and snake will only load in room 2.  The treasure are seperated from the monster sprites so I load 2 tables per room to the specific spot because the animation frame are always the same slot 42-63.  Treasure's loaded 40.  38 and below are the hall monster(14), arrows(8), and the hero Winky(if that his name if I remembered correctly.[16]).

Dig dug prototype did this with 2 sprites: https://www.youtube.com/watch?v=J_IwYEpJKA0

 Not a good video since it's 30, but you can see it the individual sprites.  I believe the video on the longplay site is 60.

I didn't try the code yet but I played dig dug prototype.

 

It's nothing but flashing sprites. I can't see three colors.

 

I used bluemsx, coolcv and colem. Same result.

Depends how fast I work. Is that a good answer?  🤷‍♂️

My goal is to get it working both using Colecovision hardware and F18A hardware using that graphic style. F18A would be interesting if I can get it working.  I'm missing the hardware for that now, but I'll worry about completing the game first then work on F18A graphics. 

I'm experimenting with sprite graphics like how Dig Dug does it but with 2 sprites producing 3 color sprites.   The treasure sprites,

left Colecovision(BlueMSX), right F18A.
 

I'm planning to make this either 128KB or 256KB, depending how large the F18a graphics are.

Venture is one of the first game I played when I got the Colecovision about 10 years ago.  So I want to remake it for the Colecovision.  The enemies will have their 4 frames movement animation and the 4 frames death animation just like the arcade, which Colecovision version had to cut 1 frame of movement and 3 frames of death due to cartridge constraint(I think...).

Thanks Kiwi.

 

I don't know 2 sprites could make 3 colors. Is F18a tricks?

 

Sorry for off topic, guys.

Now all phoenix games also work with colecovision, how about colecovision version from those screenshots below?

Here's a ''more up to date'' works in progress of Venture DX

It was first going to be developped for SNES, but it's now going to be a Phoenix exclusive game

Don't hesitate to share your ideas on how the game should be or what it should have

 

 

 

[Quarantined and a new game arrived.]

With Coronavirus around, I'd better to stay at home.

 

Fortunately, a new game arrived two days ago.

 

Gunman Chronicles

 

Because I lost internet connection days ago, I cannot play it without installing a patch until now.

 

I can enjoy the game.

 

For some reasons, gunman chronicles demo works fine with win 10 without a patch but not the full version.

 

Weird.

[Colecovision games have more contents if plugged on Adam?]

Ok. I guess programmers won't bother to put adam computer stuff in Colecovision games.

I read CV programming manual and I noted this:

 

Does it mean some colecovision games support Adam keyboard and other things?

Timex-Sinclair ZX-81 is a winner.

 

Try playing games on post-it note beside tic-tac-to.

 

If you make mistakes with post-it note and correct them, the result would be a mess.

 

And you need a new post-it note once used.

 

You won't buy a new computer if you use it once.

Now there's a take...

 

It'd be nice if things were less expensive, but that isn't reality.

Now, I'd like to see how PCs become less expensive.

[Ratillery for DOS - THE RETURN!]

Screenshots are not enough for some of us.

 

Most of time, we need to watch videos to decide.

 

[Let's Say Next Generation, A Console Manufacturer Is Going To Get Out Of The Console Market. Who's It Going To Be?]

The only way to maintain video game market is selling new consoles under $250 and new games $40-$50.

True but Dosbox runs almost everywhere these days,  on your mobile phone, some game consoles, even $30 Raspberry PIs.   Chances are you already have a device that can play these old games,  I'm not sure why someone would spend $300 for the sole purpose of running old games.  Or maybe it's me because I could build a system like that for free with all older PC parts I've collected over time.

I'm probably exaggerated with 1980s games, but there are great windows games from 1995 at decent prices available at GOG and they might run on $300 computers not counting with indie games used low system requirements as well.

Yes true.  I just take issue with people who claim that if you spend less money on a PC, you will end up with better-specced gaming system than a console for the same price. 

If you want a gaming system that isn't already obsolete and will last more than a year or two, you will be spending most of that $300 on just the video card.

No, that's a myth too.   I check the PS4 store, GoG and Steam for the best deals on games and generally find they have the same retail prices and same sale prices.   The only difference is they may not run the same sales at the same time. 

 

 

A $300 computer can play old games from 1980s and up at low prices at GOG.

 

Modern games have the same prices in retail stores and they might not run on $300 computers.

 

There are more games to choose from than we have with today consoles.

 

 

[Let's Say Next Generation, A Console Manufacturer Is Going To Get Out Of The Console Market. Who's It Going To Be?]

Why would we pay $300 today for a console when for the same price, you get a decent computer.

 

If Microsoft lefts video game market and Sony, (I heard PS5 would be the last console) what would we have at the end of the line? Nintendo and its famous games.
