    2. Atari 2600

      661,548 posts

      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

      85,521 posts

      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.

    • Thank you for giving my game a try. I'll look into the glitched title screen and find out what's going on there. I mainly use the Atari800 emulator being that I'm on Linux. I haven't seen the corrupt title screen, but I'll try to reproduce it and fix it if I can.
    • Thank you for the info on the loader, I would not have known to suggest that. I've also heard from a few different people that the initial screen sometimes gets corrupted. I'll look into that and see what's causing it, I myself haven't experienced it but I might be able to reproduce it under certain circumstances.   Also, thank you for playing my game.
    • Cable test check shows it is not set up to what documentation shows in Telco documentation but instead is:   Modem      RS232 1               1 2               3 3               2 7               7 6               20 20              6   There is other documentation that says to just hook up 2 to 3, 3 to 2 and 7 to 7 since at this time only software X-On and X-Off is needed.  I'll attempt this for the connection to see if there is a change.... 
    • I have an OG 4-port and a modded 2-port 5200.  Most of the games are great.  Depending on the game, the controllers are either the greatest thing or the most vile abomination to grace the Earth.  Playing Pac-man on the CX-52 is an exercise in patience and frustration.  Games like Space Dungeon, the CX-52 can't be beat.  Overall, IMO, the CX-52 just makes the 5200 more frustrating then fun.   Now, the Pro-Line Trak-ball controller is amazing...but can anyone tell me why there were the two keypads on it?  I get it, it was designed with symmetry, but it looks like it was designed to be a two-player unit.  What were they going to do?  Fight over the ball?  The dual keypads always bothered me about my unit, but it plays Centipede and Missile Command like it was meant to be played.
    • It would help to share your source code.  
    • For those working on controller adapters this should prove useful. Key for application signing is next up. If anyone has a spare controller they are willing to part with for a reasonable price let me know. Carl maybe I can get to the front of the queue for an adapter?     CONTROL.zip
    • Hey there, it's been a while since I last posted in this thread.   So tonight while I was playing in some of my experimental stuff involving a MIDI controller and Raster Music Tracker, I accidentally discovered what appears to be a POKEY emulation bug involving the 16-bit timing using the AUDCTL Join Channel bits, while also outputting volume on the LSB 16-bit channel (something lovingly nicknamed Reverse-16 Output).   How could I describe it and still make sense? Well to make a short description, modulating the 16-bit frequencies, while outputting the sound in the LSB channel outputs a unique kind of tone, and it does have a lot of nice musical application with enough dedication, notably, creating a harmonic tone in a pulse/distortion motion, that would also be exactly 1 octave higher than the actual 16-bit tone underneath, so this is a somewhat predictable effect, making use of the 2 pair of 16-bit channels.   Well, here's when things took me by surprise: I noticed the sound output from the ch1+2 and ch3+4 pairs is very different to each others! Specifically, only the ch1+2 pair does seem to sound correct, the other would seem to output the exact same pitch that would be in the MSB 16-bit channel output, and it would also crackle a lot whenever a single POKEY register would receive new data, for some reason.   I spent a bit more time earlier tonight to see if this was a normal occurrence, or if I was responsible for the bug in question, and to my surprise, this appears to be a bug present in Altirra for a really long time! I tested versions from the most recent test build, all the way back to 2.80, and as far as I could tell, the behaviour in question (that is, the ch1+2 and ch3+4 pairs having a big disparity in sound output) seems to have been introduced in version 2.90. Version 2.81, 2.80, and most likely further down, did not actually feature this difference, both pairs of channels will sound identical, but unfortunately the emulation accuracy of the Reverse-16 sound is also lower.   Also, I did test the exact same setup on real hardware, using both my PAL and NTSC Atari 800xl, and they do not suffer from the disparity-- each pairs of Reverse-16 channels will always sound identical. Same for the Atari800 emulator, it sounds pretty much exactly the same as hardware, in this specific setup.   TL;DR: The Reverse-16 output is most likely incorrectly emulated between channels, where CH1+2 is the only one sounding proper, while the other pair is very off. What is expected to happen is that regardless of the 16-bit pairs, the sound should be identical, as far as hardware comparisons went to confirm this was not something I caused myself earlier.   ---   Anyway, how to reproduce the effect in question? Written below is a simple way to hear what is going on, and this was also how I tested for the disparity going on for every version/platform I tested it, including RMT (where I initially noticed it):   - Using POKEY Explorer is the fastest and easiest way to showcase the bug, so first, simply load the .xex in Altirra/hardware/etc  - Next, set the 4 AUDF channels to the following frequencies, in this order: $FF, $01, $FF, $01 - Now, press the J and K keys, this will activate the Join Channels 16-bit mode to both pairs, still running in 64Khz mode   Once these initial steps are complete, do the following, and you will immediately notice what I am talking about:   - Firstly, increment the volume level in channel 1 using the 2 key to a audible level - Next, start decrementing the channel 1's AUDF value using the Q key - What will then happen is the Reverse-16 sound in action, and this should sound exactly as expected The pitch will go higher, while also the pulse wave will change its shape to modulate a different timbre as the frequency is being shifted. - Once you are satisfied of what was heard, lower the ch1 volume back to 0 using the W key, in order to test the ch3 for the same setup - Now, increment the ch3's volume level the same as before, using the 6 key - And just like before, lower the ch3's AUDF using the T key, and listen carefully the sound that will be output   From this point onward, 2 things may happen: - The sound produced is exactly the same in either ch1+2 or ch3+4 pairs --EXPECTED Or - The sound produced in the ch3+4 pair is very garbled each time a tiny change is applied, and appears to be identical to the underneath 16-bit tone if it was output the intended way --INCORRECT   The second one is exactly what happens in Every Altirra versions I tested, all the way down to the version 2.81, at this point, the 2 channels pairs will sound the same, but with lesser accuracy to what it should sound like on hardware.   ---   And that's about it, if reading this much text sounds a bit boring, here's the RMT capture I made when I first noticed the behaviour:   simplescreenrecorder-2022-05-28_22.04.18-CUT.mp4   While it is not truly the Altirra emulator, I can say for sure this is 100% identical to what the stand alone emulator also did, before I went ahead and gave a more indepth testrun. Also, for further precision, the Altirra emulation core running through the plugins used in this recording came from the version 4.00.   So yeah, like I said above, what is expected, and should happen, is that the ch1+2 and ch3+4 output must be identical, fact backed up with hardware tests a few minutes later. Thanks for reading a bit of rambling, I hope this may help tracking down why this is happening.
