  1. Thanks Xuel, I did play with HSCROL, but the offset is 4 chars or 16 pixels - far more than fine scrolling can account for.
  2. I’m having a few programming issues (which I don’t believe are related to the development language) that I thought I’d throw out to see if anyone has an idea. As per the attached DL fragment, I have set up a scrolling playfield using an entire page per line. As that the LMS instructions are set to the start of each page, and I write to the beginning of those pages, I have every reason to believe that the data I write should show up exactly at the left hand edge of the screen. It does not. The screen appears to be scrolled over 4 bytes to the right, and even with the LMS set to the start (0), I can’t see the start of the data. 112 ;blank lines 128 ;DLI 112 ;blank lines 194,192,63 ;text line 0 ;blank line 116,0,8 ;scrolling Antic 2 116,0,9 ;scrolling Antic 2 116,0,10 ;scrolling Antic 2 116,0,11 ;scrolling Antic 2 116,0,12 ;scrolling Antic 2 I can get around this issue by offsetting my writes by 4 bytes, but this issue continues to bug me. As per the attached executable, I’m getting some corruption on the right hand side of the playfield. Debug mode of Altirra shows nothing there. Code written to dump the locations shows zeros in that area, but apparently random $0F’s written and cleared throughout the lower part of RAM (under 10K) as well as the more stable phantom corruption at the far right. In the attached program, pressing “L” will print all non-zero locations between page 8 and page 32 – make sure Altirra’s printer is configured and activated. “L” will fill the same area with $03’s.You will notice that the three bytes of corruption at the right side cannot be over written. Any ideas for either of these issues would be very welcome! Thank you! TEST1.atr
  3. Thanks for everyone's feedback - I will (try to) release a version this weekend for interested people to play around with - I'm currently trying to smooth the rough edges from the interface and get the production side of the game working properly. Once that's done, the war portion promises to be a lot of fun (to program at least - hopefully fun to play as well!) At this point I'm planning to distribute the game via a (free) digital release. I may produce a very limited run of boxed copies if there is any interest, but that task is such a colossal pain in the butt I really hesitate to get involved again. :-)
  4. Announcing a new game for the Atari 8 bit computer line! Influence Influence is a single player RTS (real time strategy) game in two major parts. In the first part, you use a very large scrolling playfield (256 x 48) to explore and develop a number of plots or tiles. On each tile you can build a Village, Farm, Factory and a Mine. Depending upon natural features available on the plot, you can also build roads, power stations and resorts. Although the wealth produced in each tile is added to the player total, each tile needs to be managed individually to maintain its productivity. As well as the production elements mentioned above, each tile can contain a population of inhabitants. The more people that live on a given tile, the better its production will be. Of course, the people need to be fed and kept happy. Unhappy people turn hostile, continue to eat but do not contribute to production. Adjusting tax rates can increase production at the risk of alienating more people. At the same time as you the player are managing your tiles, the opponent is busy doing the same at the opposite side of the playfield. At some point the two sides will meet and the second part of the game will begin. War! Once on a war footing, your production will change to the creation of armaments. When you military is strong enough, you will have the ability to attack nearby tiles to either destroy the enemy outright or to take over their production. From here on in it will be a ruthless struggle for survival. The playfield consists of 96 separate tiles, is controlled by a combination of joystick and keyboard (mostly joystick) and will run on an unmodified Atari 400/800/XL/XE with at least 48K and a disk drive. http://youtu.be/hBmHZgkS5Ho As per the video, the first part of the game is mostly done (although I think I have a lot of balancing to do – right now it seems a bit easy). The good news is that the program code currently runs to just under 10K and given the Quick 20K application space, I think I will have more than enough room to finish the program properly. Although I seem to be spending variables like a drunken sailor… Please note graphics and colours are still very preliminary!
  5. Crap. I just had a closer look and my copy of Basic Psychology is a virgin. Is there anyone else who might possibly have a copy?
  6. I don't have a cassette player anymore. PM me and we can make arrangements to send them to you (assuming of course, you'll send them back :-)
  7. For the combination of commercially released titles and finished shareware/freeware, I estimate 4gb maximum. To clarify, I'm talking about executables and other content - not source code! For all the half written programs, hacks, screwing around, etc - perhaps three times that amount - perhaps a lot more :-)
  8. I'm having a few issues with restoring an 800 and I'm hoping someone can help me out. First off, the springy metal bar that is used by the lid latch is missing. Does anyone know of a good alternative? I was eyeing the spring in my wife's garden clippers but I think absconding with it might have repercussions. Secondly, the I/O bezel is missing - does anyone have a spare or know where I can find one? (I can't find it listed on B&C's site, and I don't have a Best catalog) Next, the only working CPU card I had on hand has the tin contacts. How problematic is this likely to be? Should I try to source one with gold contacts? Lastly, the keyboard is pretty messed up. Only the spare bar works. Does this suggest an issue with the keyboard itself or the motherboard? Or is it impossible to tell without more investigation? thank you!
  9. A new Basic version/label variation for the collection (second from left) SynComm - I've been looking for this for a while Now staying with friends I picked up an extra copy of SynTrend if anyone is interested...
  10. I think I have both the Basic Sociology and Basic Psychology packages, I'll check and let you know.
  11. Very nice! I have all the grey boxes, but not all are for the Atari. I do have all the Atari folios however!
  12. As promised, here is part Part 2 of the process The cartridges have arrived! thank you Steve! Now to place the correct cartridge with the correct order. I was really concerned about messing up this part - either I did a good job, or no one complained. (I''m leaning towards #2) This was a little awkward when the kids asked "Dad, um what are those cartridges doing?" Each cartridge is lovingly hand tested! Plenty of volunteers for this part! (Hard-core cartridge collectors please note the red prototype cart on the 800xl - the only one of it's kind! ... Eat your hearts out! :-) Once the cartridge passes QA, the box is numbered, final assembly and component check On to packaging - first the box protectors are cut out of large sheets of cardboard. The scored to allow folding. The local Staples as attacked for supplies... And then the box is carefully wrapped up for shipping and labeled. And finally off to the Post Office to send them on their way!
  13. Here is WNivek's description of the issue - does anyone have a similar hardware config? Or any suggestions? thank you!
  14. I'm looking to purchase a large number of the regular boring Atari Basic cartridges. If anyone has a set that they want to get rid of, please contact me!
  15. Good news all 'round! I'm just packing up the next batch and I have only 8 carts left! Once these are gone, there will be no more - ever! Don't miss out! Remaining carts are: Red Blob, Hypno-Toad, Spider, Bat, Witch and Imp Blue Witch and Imp
  16. Happy Birthday! (I wish I could say I planned that!)
