There was a planned BASIC cart for the 7800? It was really only inspired by the idea of BASIC Programming for the 2600, and me wondering what a 7800 version might have looked like.

RevEng Posted December 1, 2021 Share Posted December 1, 2021 An excerpt from atarimuseum.com (courtesy of the wayback machine)... Quote The 7800 keyboard package would also include two software titles. Most likely those two titles would have been Atari 7800 PRO System BASIC and Atari 7800 PRO System VideoWriter. And another one from Curt, from the forums here... Quote Steve [Golson] and I fired up a lot of equipment and even got the original prototype computer enhancement running, I got OSS/Atari 7800 Basic running, VideoWriter and some Atarilab modules running, 4 Quote Link to comment Share on other sites More sharing options...

+Karl G Posted January 4, 2022 Author Share Posted January 4, 2022 So, I will hopefully be releasing an early demo of what I've done with my BASIC interpreter in order to gauge interest and get feedback on the interface. Before I do that, I want to see if I can get ideas on a working name for the project. I'm not necessarily best known in this community for my clever project names. Some of the ideas I have considered are: SE BASIC: The SE was supposed to stand for Seventy Eight. But apparently there is already a SE BASIC. KG BASIC: A vanity name, but I'd only do it if I could think of a plausible (if retrofitted) meaning for the K and G, and I've got nothing. P.S. BASIC: PS standing for ProSystem. This one I think is kind of cute, but I realized it might sound too much like it was a BASIC for the PlayStation. Any thoughts on the above, or other clever ideas, perchance? 3 Quote Link to comment Share on other sites More sharing options...

Synthpopalooza Posted January 4, 2022 Share Posted January 4, 2022 I think some Graphics commands like Atari BASIC wouldn't be amiss. Same with TIA and POKEY. Possibly even put in a 4 line text window, called using GRAPHICS 0 through 6 (for all the native modes) and add a +8 to turn off the text window. 0 being of course the default 320A. other bit flags can be used to toggle double wide mode maybe. 2 Quote Link to comment Share on other sites More sharing options...

Probably most of those ideas are beyond the scope of what I'm likely to create, honestly. Right now I have a sound command that uses a 16-bit channel (distortion 10), and that should be suitable for the kinds of BASIC programs I'm picturing. I also have text foreground and background colors. If I add in any kind of graphics mode, it will be much later, and be something that would be relatively low on video RAM usage (since I only have ~16K to work with).

It's amusing since it really won't be, though (unless I find a way to produce my minikeyboard concept). The idea that it could be shortened to KGB only adds to my amusement. ? 1 Quote Link to comment Share on other sites More sharing options...

+Karl G Posted November 10, 2022 Author Share Posted November 10, 2022 I've been thinking of trying to do something similar to the old platform game "Downland" for the TRS-80 Color Computer. I'm having lots of trouble with the walk cycle despite looking at a good example for reference. Can anyone recommend any tweaks to the frames for this walk cycle?

The lives animation was indeed part of the charm of the game. It makes me wonder if it was intentional, or some side effect of how it was programmed that the developer decided to keep. 🙂 1 Quote Link to comment Share on other sites More sharing options...

No need to add anything here to the list of 7800 works-in-progress. Anyway, as I own both a QuadTari and a 7800, and knew that they should work together, I wanted to make a proof in concept game demo to see if it worked. The result is the 4-player game "Raindrops" below: Raindrops Instructions: You are a magical flying umbrella. Like all magical, flying umbrellas, you want to avoid raindrops, and catch flying rainbows. Collect 9 rainbows before your fellow magical flying umbrellas do the same. Getting the rainbow will get you one point, whereas colliding with a raindrop will kock you back to your starting position. Developer Notes: I know RevEng plans to add QuadTari support to 7800Basic, but I was impatient and wanted to take a stab at it myself. ? I set the active controllers in a topscreenroutine based on a bit set in the program. Pressing a joystick button to restart the game does not seem to work, but otherwise everything seems to work fine on hardware. Currently, there is no emulator support for the QuadTari, so it will only work properly on real hardware.

I had an idea: Alterbate between 2 charsets every frame to produce transparency AND more colors! Is this viable? I call it 160BI- allows 160B via 160A. When I get on my computer, I’ll post a demo for you. Quote Link to comment Share on other sites More sharing options...
