  1. Atari Systems

    1. Atari General

      A general discussion for Atari-related topics that aren't covered by a specific Atari console or computer forum.

    2. Atari 2600

      The Atari 2600 is the system that started it all for Atari, and is by far the most popular classic gaming console. This forum covers all 2600 systems produced by Atari, as well as 2600-compatible consoles produced by third-parties.

    3. Atari 5200

      The Atari 5200 was Atari's second cartridge-based game console. Based on the Atari 8-bit computer line and labeled the "SuperSystem", the 5200 was Atari's answer to growing competition in a market they were losing control over.

    4. Atari 7800

      The Atari 7800 ProSystem is a contemporary of the Nintendo Entertainment System and the Sega Master System. Based on extensive feedback from Atari customers, the 7800 features a streamlined design, backward compatibility with the 2600, a powerful graphics processor, and simplified controllers.

    5. Atari Lynx

      Lynx was Atari's first portable game system, and world's first color handheld. It was designed by Epyx and the engineers who created the Amiga. Ahead of its time, the Lynx sported a backlit color screen, stereo sound (in model 2) and an impressive range of games. Check out our rarity guide or explore many games listed on Atari Gamer.


    6. Atari Jaguar

      Atari's last game console, the Atari Jaguar represented a huge leap in technology from previous offerings. Featuring a 64-bit architecture, the Jaguar had great potential, but its power was difficult to tap. Even then, many great games were released and the Jaguar has an avid fan base today.

    7. Atari VCS

      Discussion forum for the new Atari VCS console.

    8. Dedicated Systems

      Before Atari produced the famous 2600, they created many standalone consoles such as Pong, Speedway, and Stunt Cycle. Recently, Atari has been creating new dedicated consoles, such as the Atari Flashback.

    9. Atari 8-Bit Computers

      Atari's original 8-bit computer line, featuring the Atari 400, 800, XL, and XE series of computers. Powerful and well-engineered, the Atari 8-bit computers are still popular with fans today!

    10. Atari ST/TT/Falcon Computers

      Atari's next generation computer line, the Atari ST computers were based on the Motorola 68000 series chips, the same as the Macintosh at the time. The ST would also be followed by the TT and Falcon.

    11. Atari Portfolio

      The Atari Portfolio is a palmtop, IBM PC-compatible portable computer released by Atari in 1989, the world's first palmtop computer!

      Time for Slave Zero!
      Standing on the shoulder of Slave Zero - Good Gear Guide by PC World Australia (archive.org)
      I'd advise getting it on GOG.com instead of Steam:
      Peixoto's free patch: https://www.patreon.com/user?u=44312848
      Said patch doesn't require one to subscribe to his Patreon. Hopefully, Night Dive Studios will remaster this game.

      Unfortunately, it appears that the "What have you been up to lately with your Cybiko" thread was an utter flop.

        I found one of those in a box a while ago. I should have it in my lab closet. Is it worth digging out?
      2. Cebus Capucinis

        I doubt it. I'd be very surprised if there's actually any use for them these days.
      3. bent_pin

        Those square batteries looked cool though, and completely impractical. 
      4. Cebus Capucinis

        Apparently you can still get the games with soldering and a ton more effort than it's worth. The other functionality (email, MP3, chat) is fully deprecated now.
      5. bent_pin

        So much work to polish a turd. I'd rather try to swap in an esp32 and microswitches for the kb, or I could just slam my head against the wall a few times for a similar effect.

    • It is an MCP3202, is that not right?
    • This would be a good question for @Andrew Davie   I guessing he could draw the screen like Wen Hop and make a very decent looking version of the game.
    • The dpad is behaving as if the keypad is missing the column bits. If the game controller isn't working as expected you can try it in dpinput mode rather than xinput mode.  You can also try the sdl1 version of jzintv.  Here's a hackfile I might use for Ad&D.  It maps the Intellivision disc to the right thumbstick so I can shoot arrows with the dpad.   Map 0 JS0_BTN_10 RESET JS0_BTN_11 PAUSE JS0_BTN_04 PD0L_A_T JS0_BTN_06 PD0R_KPC JS0_BTN_07 PD0R_KP0 JS0_BTN_05 PD0R_KPE JS0b_E PD0L_J_E JS0b_ENE PD0L_J_ENE JS0b_NE PD0L_J_NE JS0b_NNE PD0L_J_NNE JS0b_N PD0L_J_N JS0b_NNW PD0L_J_NNW JS0b_NW PD0L_J_NW JS0b_WNW PD0L_J_WNW JS0b_W PD0L_J_W JS0b_WSW PD0L_J_WSW JS0b_SW PD0L_J_SW JS0b_SSW PD0L_J_SSW JS0b_S PD0L_J_S JS0b_SSE PD0L_J_SSE JS0b_SE PD0L_J_SE JS0b_ESE PD0L_J_ESE  
    • Thank you for confirming my observation that the artist did no butcher his own work.  
    • To tell you guys the truth, I wanted to get into GameCube homebrew development. Hell, I even bought a set of the mini-DVDs the system used. It would be nice if Bitmap Bureau found a way to have XenoCrisis run on a stock GC...
    • I’d love to see it. My name would be Craig Abruzzese. But if you want to pm me the list I’d love to see some of my old friends name. 
    • Look at this beauty. Texas Instruments MC 390 P   The seller spent time testing and characterizing this camera!  (for lack of a manual).    Here's another one in box.   Bell Labs researchers, Willard Boyle and George Smith, invented charge-coupled devices, or CCD, in 1969.  The idea is an array of cells, which charge up from incident photons. Then the device operates as a shift register.  Stored charges are read out one by one, as they are shifted toward one end. (Parallel in, serial out.)    Curiously, they initially called it "Charge 'Bubble' Devices" because it operated like magnetic bubble memory.  Bubble memory was a non-volatile magnetic RAM,  operating as a serial-in, serial out shift register.  Not so great as a memory, perfect as a camera sensor.   After licensing the CCD invention from Bell, TI built up a profitable and fascinating business.   (More profitable than bubble memory!)              
    • This rule should include not only logical statements, but loop conditions as well.  For instance, consider the following FOR/NEXT loop, which counts down to zero: For I = 10 To 0 Step -1 ' ... Next   That code compiles into the following assembly code (formatted and annotated for clarity): ; For I = 10 To 0 Step -1 MVII #10, R0 ; \_ Initialize the loop control variable MVO R0, var_I ; / T1: ; ... ; Next MVI var_I, R0 ; Get loop control variable DECR R0 ; Decrement it by one MVO R0, var_I ; Save new value CMPI #0, R0 ; Compare new value to final value BGE T1 ; Repeat if greater   It is clear that IntyBASIC understands that the loop counts down, since it translates "Step -1" into the specialized instruction to decrement by one (DECR).  It should then just be a small step from there to also understand that the end value is zero, and use the specialized instruction to test for zero (TSTR) instead of the more expensive general comparison to a constant (CMPI).   That code could look something like this: ; Next MVI var_I, R0 ; Get loop control variable DECR R0 ; Decrement it by one MVO R0, var_I ; Save new value TSTR R0 ; Compare new value to zero BNEQ T1 ; Repeat if not zero   In fact, armed with that awareness of the loop control values, it can skip the test completely!  You see, the DECR instruction will automatically set the Zero or Sign CPU status flags whenever the value decrements to zero or a negative value, respectively.  That means that the outcome of the TSTR instruction is already provided as a result of decrementing.   The code can then be optimized to exploit that: ; Next MVI var_I, R0 ; Get loop control variable DECR R0 ; Decrement it by one (signaling zero or negative) MVO R0, var_I ; Save new value BNEQ T1 ; Repeat if not zero   Avoiding the extra CMPI from the original code saves 8 CPU cycles -- not a bad deal, especially considering that the savings are per iteration.  Those cycles can definitely add up in a long-running loop.         -dZ.
