Atariboy2600 Posted February 28, 2006 Share Posted February 28, 2006 This game was on both 2600, 7800 and even on the XE but I never see it on the 5200. So I wonder if anyone can post the XE game of Crossbow to the 5200 or is it that you need a gun port for the unit? Quote Link to comment Share on other sites More sharing options...

Atariboy2600 Posted February 28, 2006 Author Share Posted February 28, 2006 Yea if that the case this could be the first 5200 gun game^_^ Crossbow for the XE: Quote Link to comment Share on other sites More sharing options...
Gabriel Posted February 28, 2006 Share Posted February 28, 2006 Gah! I remember Crossbow. For about a month or two it was my favorite arcade game EVAR! I remember going to the arcade at the mall and having to wait in line to play the thing. There were crowds around it all the time. Then, one day, no one was playing it anymore. Oddly, I remember playing the game during that phase and just suddenly not caring. This is one that I need to play again and restore my memory. I literally can hardly remember anything about the game other than I played it and loved it for a short period of time. And any new classic arcade games to play on the 5200 would be welcome.

SteveW Posted February 28, 2006 Share Posted February 28, 2006 I'm just wondering how it'll control with the 5200's analog stick. Quote Link to comment Share on other sites More sharing options...

Bryan Posted February 28, 2006 Share Posted February 28, 2006 Here's a little problem. Atari could have hooked up the light pen input on Antic (pin 4) to the trigger on port 1, but they didn't. It's simply pulled high. -Bry Quote Link to comment Share on other sites More sharing options...

Cobra Kai Posted February 28, 2006 Share Posted February 28, 2006 Analog control would have worked great on 5200 Crossbow, and the non-centering action would have actually been a plus. This game would probably be best with the trak-ball, it's mechanics are similar to Missile Command. Now, is that pic of the XE version what this game would look like for the 5200? That's not too bad if that's the case, I would buy this if it was ported and I could use my trak-ball. On topic, and one question I've often wondered. Why wasn't the very similar game Cheyenne ever ported to the 7800? It's just as fun as Crossbow, only with a different time period(the wild west).

ziggystar Posted March 3, 2006 Share Posted March 3, 2006 Interesting this came up. We (MHS) recently aquired the rights to all of Exidys games, including crossbow! I'd like to see this happen too, anyone with the talent that wants to try, PM me. Quote Link to comment Share on other sites More sharing options...

Are you going to program some new versions of Exity's games on some console/consoles? Just curious. Allan Quote Link to comment Share on other sites More sharing options...
moycon Posted March 4, 2006 Share Posted March 4, 2006 Dont forget Chiller!! What would really make a mint if marketed would be a plug and play light gun that had all the Exidy gun games in it. You know one of those units that just hooks directly to the TV. I'd buy something like that in a second. Quote Link to comment Share on other sites More sharing options...

Shawn Posted March 4, 2006 Share Posted March 4, 2006 Dont forget Chiller!! That was my all time favorite arcade shooter! 1027856[/snapback] You mean to say there are others aside from me that like chiller? Anyone I personally knw always thought it sucked, I love the game. But then again alot of peope have only played the NES port (if you wanna call it a port), it's good but no arcade version, and the 5200 could make it look alot better on console than the poorly mad nes game. Also to heck with all the exedy gun games on a plug put them on an ATARI mulitcart. But back on track, so is this crossbow 5200 gonna get a gun or what?

If someone were able to make a modification, would you be able to use an XE lightgun with the 5200 through one of the redemption/masterplay interfaces? Dont forget Chiller!!

This game found its way into the Beefsteak Carlies restaurant when I was a kid. I didn't play it as much but only because it was the one game in there that was 50 cents to play rather than a quarter.

If someone were able to make a modification, would you be able to use an XE lightgun with the 5200 through one of the redemption/masterplay interfaces? Definitely not. The adapters aren't intended to handle light guns. It's doubtful that the necessary pins are even connected to anything, much less forwarded through. The 5200 also doesn't have a free pin for the lightgun input, so there's no way to get it from the DB15 to the DB9 even if the existing adapters could support lightguns. What you COULD do is tap the 4 lines you need and run them to a DB9 placed in an unobtrusive spot on your 5200 case. Or right out the top, if you're a dirty swine with no respect for aesthetics.

Bryan Posted March 4, 2006 Share Posted March 4, 2006 (edited) A light gun can be connected, it just can't be polled the easy way. What you would do is wait for the trigger to be pulled, then set the background to a bright color and turn off DMA for one frame and wait for the sensor to see the beam with a software loop. You could probably get reasonable accuracy this way. -Bry Edited March 4, 2006 by Bryan Quote Link to comment Share on other sites More sharing options...

You don't even need to tap out a XE gun, just rewire a SMS gun seeing as this is a hwardware project to begin with why not add the SMS into the works (seriously).

Bryan Posted March 4, 2006 Share Posted March 4, 2006 (edited) Here's exactly what you do: Wire up a light gun so the trigger is wired to the top button. Wire up the bottom button to the photosensor (must be active low). Every frame check to see if the trigger (shift) is pressed, then: 1. Wait for the beginning of a frame. 2. Turn off all Antic DMA and set the background to a bright color. 3. Enter a software loop that counts and reads TRIG0 over and over across a line. This will look something like: test1 LDA #0 LDX #4 STA GRACTL STX GRACTL ;Reset Latches CLC ADC TRIG0 ADC TRIG0 ADC TRIG0 ADC TRIG0 . . and so on... The value you get will tell you how far into a line you were when trig went low. 5. If the latch is triggered, save the horizontal position and read VCOUNT for vertical position. 6. When VBI occurs, turn on Antic DMA and resume the game. With DMA off, you should be able to achieve reasonable resolution. You'll have to adjust the horizontal position for the 9 refresh cycles on the left half of the screen as well. -Bry Edited to elaborate: I did some more thinking, and I'd probably do the scan every other line (that's all the resolution you'll get from VCOUNT anyway, and you'll probably get even less from the gun). I'd use one line to check TRIG0, then the 2nd line to figure out what happened and then WSYNC to start the next cycle.

Get crossbow over to the 5200 and start working on the patching the code to support the gun. You can do it and I will buy it. Sound fair?

Tempest Posted March 5, 2006 Share Posted March 5, 2006 I always thought that was the damn ugliest artwork for Crossbow I've ever seen. I've never liked it. I remember the artwork for the Apple IIe version was pretty cool, but I can't seem to find a picture of it ATM. Tempest Quote Link to comment Share on other sites More sharing options...
