Scramble - 2600

As a sidenote: is autofire missing from the released version? I just got hooked again and found my poor fingertips longing for it soon after :D

We felt autofire made the game too easy - it removed any need to think about your shots/bombs, which is a key part of Scramble's gameplay. As a compromise, we changed it to "burst mode", which autofires a string of shots, but requires you to re-press the button for each burst. Of course manual fire is still there for people who want to play the game properly. ;)

Can't get it to work here, no combination of switch positions does the trick.

Whatever ROM version burned onto the cart I purchased from the AA store works when played on hardware.

 

One minor gripe is the "auto-fire" affects the bombs as well, resulting in double shots every time I tap the button. I made a modified SMS schematic that detects as Genesis controller on the Atari 2600. Toggle switch selects SMS+ and 7800 modes:

This also works great if you want turbo on the bullets but not the bombs:

I generally just use standard mode since "burst" mode trips me up too much.

Okay! Got it working. VisionDapter set to Autosense with a 7800 controller. Used Joy-to-Key to to map joystick to keyboard, then mapped Stella 5.01 to keyboard with booster/trigger both set to 4. Both Stay Frosty 2 and Scramble2600 work in 2-button mode.

 

Edit: Can't seem to even get movement doing this with the 2600daptor set to 7800.

 

Thanks for your help!

 

Vision-daptor supports Genesis 3 & 6 button and 7800 Pro-line. Hold the Genesis Start button for the auto detect. It's been a long time since I looked at the Genesis and 2600-daptor, so I'll have to go back and look at that again. Currently out eclipse chasing, so will be a couple days.

If you are referring to Scramble2600, the fastest you can fire is 3 shots/2bombs per button press in burst mode. Probably need an auto-fire module for continuous firing.

Makes sense :) I guess I'll have to add an autofire mode to 6502.ts in order to keep myself from smashing in my digits and / or my keyboard :P

Cartridge_Name

Cartridge_Note

Sure!

 

NTSC:

 

Cartridge_Manufacturer: Champ Games

Cartridge_ModelNo: CG-03

Cartridge_Name: Scramble (NTSC)

Cartridge_Note: Compatible with Genesis controller

 

PAL60:

 

Cartridge_Manufacturer: Champ Games

Cartridge_ModelNo: CG-03

Cartridge_Name: Scramble (PAL60)

Cartridge_Note: Compatible with Genesis controller

 

 

Thanks,

John

I used SW-01 for Medieval Mayhem, perhaps CG-01 for Lady Bug, CG-02 for Conquest of Mars, CG-03 for Scramble, and CG-04 for your forthcoming project.

 

I see some Notes mentioning support for the Genesis controller, such as Princess Rescue, which would make sense for Scramble.

 

On that note, looks like I need to submit some updates as well - I don't see Stay Frosty 2 or Space Rocks, and I don't believe Stay Frosty was stereo (entry was probably was cloned from Medieval Mayhem). Will work that up tonight.

Thanks for the feedback Darrell!

 

Stephen - I have updated the post above with Darrell's suggestion. Could you update the Model number for Lady Bug and Conquest of Mars (both NTSC and PAL versions) to be CG-01 and CG-02, respectively? Actually, should the model # be different for NTSC and PAL versions? (ie. CG-03-N for NTSC and CG-03-P for PAl60, for example?)

 

Thanks,

John

Properties database??? within Stella?

 

 

Yep, I linked to it in my prior reply. Stella uses the info to configure controllers, TV-Type when it can't autodetect (like for PAL60), if the sound is stereo, etc. It's indexed off the MD5 value for the BIN file, which you can view in the Game Properties page:

I still need to work up the rest of mine, got a bit side tracked getting ready for Hurricane Harvey. Looks like it'll hit near my sister down in Corpus Christi, but we're still expecting to see a lot of rain and flooding here in Houston.

Cool! I never realized Stella did that!

Hi guys, I programmed the NES version of this that was referenced a few pages back by a few people and I just wanted to pop in here and comment on a few things:

 

I am a huge arcade enthusiast, having already ported Frogger over to the NES, and Scramble was a game that I've had in the back of my head for years as a game that I had wanted to port over to the NES (which is my favorite game system). The one thing that held me back was in the arcade version of Scramble, a lot of the terrain is curved, and I am not a super talented coder, so I never knew how to tackle this issue.

 

I have been at PRGE for the past three years, and when I arrived this past year and saw Scramble for the 2600 I was blown away by how good it was! It got my mind working into overdrive and it inspired me to take what he did and bring it over to the system I love and know how to code for. I in no way meant to take away from any of the work done on the 2600 version, or give any impression that I stole any of his work. I was merely super inspired by how amazing it was and wanted to use his "blocky" terrain idea in my version. I actually watched videos of this port on Youtube and paused it at every new screen to try to keep track of the undulation and use it in my version. I apologize if this comes off as stealing, but it's more a lack of creativity on my part. The 2600 version that was created by John really is a masterpiece!

 

On NES it's a lot easier to keep track of collision in a 8x8 tile fashion, and it was basically a eureka moment seeing John's version that I could take it over to the NES. I started work on my version the day I got home from Portland and had it done by the first of the year. It was the fastest I had ever worked on a game, but it all came together very quickly having seen that it could be done.

 

So seriously, thank you John for bringing your version to light, and I'm sorry if you have any ill will toward me. I have nothing but respect for you and what you do, and I want to thank you for making one of my dreams come true by showing me how this game could be handled on older systems.

I feel a little silly linking my game in a thread that is for John's version, but it can be found in my store here:

Thanks - I'm going to order this!

 

 

Is there a video of your game in action?

 

I found this. Unfortunately the guy is blabbing throughout over top the game sound effects
