Hmmm This same sample. blf- play on vcount embex- on dli blf.xex embex.xex

It is ok for demos but not for the game. We have to balance between speed and memory.

Wow hardcore @Heaven: Now I know what you means "precompiled" sprite data+code I haven't used any advanced optimization code.

@analmux: You have here the same thing. http://asma.atari.org/asmadb/search.php?play=3357 @Heaven: Software sprites using Pre-Shifted Data.

analmux - perfect

18 sprites - 16 line high each Sprite data 576 bytes, change every frame. It all takes 72 cycles.

@Heaven: Did you notice that the animation all hardware sprites takes only ......... 72 cycles? @Philsan: I can only say that I'm working on something similar.

Press fire

Not necessarily. Embex25fps.xex

Version 25fps Hardware sprites still 50fps because they don't take Cpu time at all. And now we have 1 empty frame for game logic and whatever we want Embex25fps.xex

About 120 lines. It's 50fps. This was the reason why I did this demo. That is why there is no buffering background. I have to try to play fx samples by another method. But I must say that after converting even to 3kHz - 8bit - sounds bad on PC. Small update You can use joystick now Embex.xex

We can use Pokey Timers, CPU, or DLI. Dli is the worst option for quality. But it is not so bad. I need to check how it will work with sound effects.

That was my idea. To check out how to play the sample at DLI. Even though they are not packed. I did not want to waste cycles.

59 DLI This is my fault. My conversion sucks. But 3kHz for the sound effects will be fine.

Talk is cheap....... Embex.xex

Tell me how it is done. That does not sound like c64.

I don't have clue.

Check it out. http://www.atarimania.com/game-atari-400-800-xl-xe-airball_151.html

@José: the screen starts with the address $E000, I forgot to clean it. @Tezz: veeeery long day

only 3 kHz (6 kHz sounds much better)EmkayMode.xex

Nibble now (2 color cycle) The target is to be a cycle. Yes. But my idea was check how many objects I can put on screen with digital sound (3kHz) I try to use tricks to make it look good and that there was a lot of objects. But this will be next week. Today I did nothing. It was nice weather. And this is a rarity in the UK. Trust me.

Ok. Some minor changes. Next week I'll try put extra 12-16 objects and animate all of them. Of course with 50 fps Hmmm... I think will be good idea do something in future in Emkay mode EmkayMode.xex

x - 1 byte y -1 line mode 13 antic Because now I use 2/3 of CPU time. Yes it's Vcount Yes It was written quickly to see Emkay mode. But backround could be on PM ,like in BloodFire. I'll try improve this today.

Emkay Mode continue Small changes and code optimization. Emkay this digi could be easily 6kHz. Now is 20 objects. Program start on grey line and finish on blue line. I think we should name this Embex (EMkay+ZyBEX). It's still 50fps. Hehehe Sorry for the graphics but I'm not talented. With 25 fps could be about 60 objects EmkayMode.xex

This is different thing Atari signal is 50 full frames per sec. Anyway screen on your tv is refresh 50 times per sec
