Gorf Posted February 13, 2008 Author Share Posted February 13, 2008 I was thinking flipping frames of playfields Doing that without excessive flicker is apt to be difficult. Further, even if the playfields are symmetric the spikes wouldn't be. I would think the 4A50 cartridge would be the best approach for doing a game like Tempest (actually, it's one of the games I had in mind when I wrote it). A 104x192 flicker-blinds bitmap screen with alternating scan lines colored blue-cyan and orange should work pretty well, and 4A50 has just about the fastest pixel-plot of any 6502-based machine. If the coordinate is in the X and Y registers, just: lda $7F00,x ora $1E00,y sta $1E00,y Three instructions, thirteen cycles. It's possible a future 4A50 might improve that further (to nine cycles, and not trashing the accumulator) but that's being pretty optimistic. It's what I was thinking. But so far it's only a start and I will be needing help from the guru's on this one. The Super Cart is a great Idea BTW! Quote Link to comment Share on other sites More sharing options...

tremoloman2006 Posted February 13, 2008 Share Posted February 13, 2008 Tempest never looked so damn good on a home TV screen! Keep up the great work! Quote Link to comment Share on other sites More sharing options...

+Random Terrain Posted March 14, 2008 Share Posted March 14, 2008 So what's happening with this? Looks cool so far. Will it eventually have a rapid-fire option so you don't have to keep hitting the fire button repeatedly? Quote Link to comment Share on other sites More sharing options...

Will it eventually have a rapid-fire option so you don't have to keep hitting the fire button repeatedly? Hehe....have not gone near it.....another project(or so) is in front of it. However, it would not be much like the real game if you dd not have to pound the fire button.....you will need a VCS DC...modified with another button. I suppose I could look at the option of a rapid fire...or..make you earn it....yeah....more likely make you earn it....besides, you'll appreciate it more. Anyway I will eventually get back to it but I still need a seasoned 2600 code master to help me figure out a few tricks.

wrenchien Posted March 14, 2008 Share Posted March 14, 2008 Thats incredible! You are doing an EXCELLENT job on this! I'd love to see a 5200 AND 2600 release of TEMPEST in 2008! Looks like the groundwork is laid out for BOTH of them! Let's see them HAPPEN!!!!! - D yes. Quote Link to comment Share on other sites More sharing options...
Gorf Posted March 15, 2008 Author Share Posted March 15, 2008 Just let me say...dont count on Tempest 2600 this year.You'd be building yourself serious false hopes. Quote Link to comment Share on other sites More sharing options...
Keatah Posted April 3, 2008 Share Posted April 3, 2008 OMFG!! make it happen dewd!! This is k-rad and so cool. That would be great fun to pit the two systems together, like a 2600(running your version of tempest) and a core duo with 9800gtx grafix bored running typhoon 2001.. side by side, then & now, yesterday & today. 8bits(crippled 6502) vs 384bits(grafics boared) yeh I would have a hard time figgering out which would be most fun..

tremoloman2006 Posted April 30, 2008 Share Posted April 30, 2008 I don't know if this has been suggested already or not but if you could make this run with the driving controller it would truly ROCK! If this cart becomes a reality sign me up first on the list! I'll plunk down some good moola for a copy! Quote Link to comment Share on other sites More sharing options...

accousticguitar Posted April 30, 2008 Share Posted April 30, 2008 Yes, please use the driving controller. I can't stand playing Tempest with a joystick. Quote Link to comment Share on other sites More sharing options...
Gorf Posted April 30, 2008 Author Share Posted April 30, 2008 There will be options...if and when I gt back to the game that is. Quote Link to comment Share on other sites More sharing options...
Dutchman2000 Posted April 30, 2008 Share Posted April 30, 2008 Gorf- I salute your effort, it would be awesome if this could be finished. Take your time and make it great! Let me know if you have any questions about the gameplay. I have access to the coin-op source as it is a great help for the 5200 version.

I will...I can definitely use a tempest gameplay expert....keep in mund I know little of the 2600 and you should all thank Fred Quimby for bB. I will need a 2600 kernal wizard more than anything.

Gorf Posted May 8, 2008 Author Share Posted May 8, 2008 Even with the source, It's been quite a few years since I did the 6502 thing. This is bB based. However, I know you can use some form of inline assembly with bB but the trouble with that is this is still bB based and therefore so is the kernel. As it stands....the bB kernel is a symetrical screen (right side mirrors the left side) which will make the spikes pretty much impossible or not at all similar. I know there are ways to do asymetrical screens on the 2600 and is why I need a brilliant kernel writer. As far as the source of Arcade Tempest is concerned, it would probably take me a while to get back up to speed to be able to decifer it all in any reasonable time frame. It would probably just be easier for Dutchman 2k to post me a few notes. Keep in mind we only have so many cycles here. The 5200 has many more cycles and advantages over the 2600 so it's not a port i'd curse anyone with. I'm just insane enough to give it a try.

Keatah Posted October 2, 2013 Share Posted October 2, 2013 Can this be beefed up with a harmony cart and be made? Quote Link to comment Share on other sites More sharing options...
+Random Terrain Posted October 2, 2013 Share Posted October 2, 2013 Can this be beefed up with a harmony cart and be made? The DPC+ kernel didn't exist back in 2008, so I bet the answer is yes. With 10 multicolored sprites and a higher resolution playfield, someone should be able to make something cool. Gorf got himself banned, so somebody else would probably have to do it.
