LS_Dracon Posted December 11, 2006 Share Posted December 11, 2006 (edited) Hi people I hope demos can be posted here... I'm start do make demos, to get better atari hardware knowledge and programming itself before my first original game. I create this topic for don't need create one topic for every single demo that I finish... So all will post here. At this time I brought to you a Donkey Kong sprite demo. The port of 2600 had sad sprites, so I try make a better looking. I don't know how to use both players at same time and same positioning using 16 bit sprite data (GRP0-RESP0-GRP0, GRP1-RESP1-GRP1?), so I use flickering sprites. See above the image for comparission : 1- Original from arcade 2 - My try 3 - Official port for 2600 (get me sick ) This use 2 colors, 16 bit wide sprite, and a animation. Ah, the white part is a ball hidden behind players What you think? Here's the binary, it's just a graphic demo. (new version at bottom) (Sorry my poor english) Edited December 12, 2006 by LS_Dracon 1 Quote Link to comment Share on other sites More sharing options...
Albert Posted December 11, 2006 Share Posted December 11, 2006 I tried this out in Stella 2.2 (in OS X) and poor Donkey Kong is split in half with a fair amount of distance between his two halves. Him and Mario look quite good outside of that, though. ..Al Quote Link to comment Share on other sites More sharing options...

SeaGtGruff Posted December 11, 2006 Share Posted December 11, 2006 What you think? It looks good, but next time, can you post a larger image? It's a little hard to see it. Michael Quote Link to comment Share on other sites More sharing options...

xybot67 Posted December 12, 2006 Share Posted December 12, 2006 I tried it on Z26 (no split). It looks fantastic!! Keep up the good work. Quote Link to comment Share on other sites More sharing options...

I don't know what's going on. As for the screenshot issue, this game seems to use 30Hz flicker mode. So if you take a snapshot, you're only going to get one half or the other. Turn on phosphor mode (Alt-p), then the snapshot will include both parts (phosphor mode actually blends two frames together). Quote Link to comment Share on other sites More sharing options...

That's normal because the full graphics are not displayed every frame (hence the flickering). If you take a snapshot, you'll only get what's on the screen during the frame the snapshot was taken. Normally in this case if you want a "full" screenshot, you need to composite the frames together (using Photoshop or some other image editing tool). ..Al Quote Link to comment Share on other sites More sharing options...
Zach Posted December 12, 2006 Share Posted December 12, 2006 Just tried on a real Atari (used a Krok Cart), and z26 gives a more accurate picture than Stella. The flickering might look better if you do it Venetian style. Quote Link to comment Share on other sites More sharing options...
Uzumaki Posted December 12, 2006 Share Posted December 12, 2006 I tried it on my emu and I'm also getting a split DK plus there's a large white square appearing a lot next to the left half's face. Quote Link to comment Share on other sites More sharing options...

Thanks for the tip. That will save me a lot of time when trying to take snapshots of new games (which I've done a lot of in the past week!) ..Al Quote Link to comment Share on other sites More sharing options...
SeaGtGruff Posted December 12, 2006 Share Posted December 12, 2006 What you think? Tried it on z26 and it looks great! Weird about Stella splitting it up, though. By the way, z26 shows that you've got 263 lines, so you might want to fix that. It's no big deal for NTSC, but if your line count in off on PAL versions, they say it will mess up the colors.

+SpiceWare Posted December 12, 2006 Share Posted December 12, 2006 Looks ok on a real Atari Quote Link to comment Share on other sites More sharing options...
+batari Posted December 12, 2006 Share Posted December 12, 2006 The "split" in Stella seems to be due to a bug with RIOT emulation, i.e. the horizontal positioning uses the RIOT timer (TIM1T). Quote Link to comment Share on other sites More sharing options...
LS_Dracon Posted December 12, 2006 Author Share Posted December 12, 2006 (edited) I tried this out in Stella 2.2 (in OS X) and poor Donkey Kong is split in half with a fair amount of distance between his two halves. Same here via XP in the office running Stella 2.2 You're right, I tested only in Z26. Sorry, my fault But thanks to advice. Fixed! Now works ok on stella too. I tried it on Z26 (no split). It looks fantastic!! Keep up the good work Tnx, but fantastic is that dragon from Medieval Mayhem, without flicker... Just tried on a real Atari (used a Krok Cart), and z26 gives a more accurate picture than Stella. The flickering might look better if you do it Venetian style. Venetian? Sorry I don't understand... you spoke interlaced lines? Like the letter code? Looks ok on a real Atari Really? cool The "split" in Stella seems to be due to a bug with RIOT emulation, i.e. the horizontal positioning uses the RIOT timer (TIM1T). Or this code aren't efficient I'm still learning... Tanks for all.

LS_Dracon Posted December 13, 2006 Author Share Posted December 13, 2006 Tnx AtariBoy Not so real, but I try more close as possible. This game is very hard to program, don't wait, in future maybe There's a new update, more sprites like princess and that fire thing.

Gregory DG Posted December 13, 2006 Share Posted December 13, 2006 I get a lot of flicker in z26, but aside from that, it looks great! (Dare I say better than the 8-bit version?) Quote Link to comment Share on other sites More sharing options...

If he keeps up making this game more and more like the arcade I think its may well be better then the 8-bit DK I mean look at Mario from here and tell me hes looks more like the arcade then the XL vesion.

+Nathan Strum Posted December 13, 2006 Share Posted December 13, 2006 There's a new update, more sprites like princess and that fire thing. Work on Z26 and Stella emulators. That's astonishing! Nice work! (You realize though... nobody is going to leave you alone until you actually program the whole game now.) Quote Link to comment Share on other sites More sharing options...
