Re: Sprite List Code Messed Up

addq.l #4 , a0 ; increment address by a word [several times:] addq.l #2, a0 ; increment address by a byte Ups! what you say is not what you do. To increment 2bytes you should add '2', to increment 1byte you should add '1', or better a post-increment. Anyway, perhaps you should reconsider the whole ...

How do you "trigger DMA in a slower way"? Do you mind later in time? wait a few more cycles?

Re: 16 colors 1 hscan

I don't follow, what causes the garbage at the left of the image? Is just a matter of precision or is there something else?

Re: 16 colors 1 hscan

If you are developing a game, what are you going to do: use the 100% of the cpu just to wait for the correct scanline?
A smart solution, proposed by other members, is to use the h exception of the previous line and then check for the wanted line on the counter.

Re: War in the Machine for the Sega Genesis

Well... you can always create a global polemic, like Midway did with Mortal Kombat, but if you are not ready for it (joking), you can always put some images for example.

Re: Algorithm for splitting sprites

Ok, going to the point, you first try to fit sprites into the image, and then secondly find empty tiles inside the shape of the image and rearranging previous sprite fittings. Is that correct? One striking thing I discovered trying to find an optimum algorithm is that changing only one tile could ch...

Re: 'torch' effect ?

Also notice you can do it all, including the "blur effect", with palettes. In fact, palettes are the most powerful technique there is, most of the timer overlooked because they are easy.

Re: War in the Machine for the Sega Genesis

There is a reason why videogames companies expend about half of their expenditure on advertising.
Hope you don't find this as an attack, but as a suggestion.

i wonder if it could also be done by sprites, using shadow/hightlight ?
As the image you post no. Other sprites will be not obscured or, totally hidden while the scenario remains visible.

But you can do it with normal sprites.

Re: Adventure of Lolo

If you are really interested you should find legal precedences. For all I know similitudes are acceptable, even very close ones, while cloning is not.

I don't think you should do the game any different but if you want it to be more likeable it's all about fine tuning it.

Re: Adventure of Lolo

Is it fun? Fun is a cultural factor, and that means that anything can be fun, no exception, if you give it the adecuate context. I can't get pass the watter, but so far... I feel that the game needs to acompany more the player, explain more the situation (but I usually apreciate no words), give rew...

Nice to read document, but for the current matter adds no advance. A bit off topic, but, there is always been people fascinated by Aladdin game, while is a definitely a good game, I was never been able to understand what makes it been seen above the rest. It was advertised very pompously on its laun...

Re: The legend of Leyria - Rpg for Genesis

I'm surprised at those lights and shadows. Have you already planned how to make them a reality?
