    The fact that some of you are more concerned about his boxes getting crushed and ruining their value is kind of scary.

     

    Especially since this is so obviously a shot across the bow at the psychotic collector types who store toys most of the world no longer wants in hermetically sealed Mylar cases. If you think it's a cardinal sin to leave these games strewn about, you missed the joke.

    Did you look at the link I posted? http://home.comcast....2600-daptor.htm

    New 2600-daptor II

     

    The 2600-daptor II adds support for 7800 Pro-Line, CBS Booster Grip, and keypads (Keyboard Controller, Video Touch Pad aka Star Raiders, Kids Controller). It has 3 modes - 2600, 7800, keypad - set by switches

     

    Confirmation here if you still have doubts: http://www.atariage....50#entry2500432

    Welll sheeeeeiit. That's new. Never ever heard of it before.

    Looks like we have quite a bit of misinformation, misconceptions, or outdated material in this thread...

     

    1. This... http://home.comcast....2600-daptor.htm ...will allow your Atari 7800 controller to work fine under Windows including MESS/MAME.

    2. MESS/MAME will recognize any controller or button input that Windows recognizes under the Game Controller (Control Panel).

    3. MAME/MESS has trackball support, including fine tuning for the analog sensitivity and a plethora of other adjustments not found with any other emulator for the 7800, including video adjustments/tuning and proper YUV emulation support (Makes your modern display look just like a traditional CRT TV...Example: http://www.atariage....2/#entry2660238)

    4. There are a handful of games with very minor graphical issues for the 7800, a couple with major graphic issues/timing issues, otherwise most 7800 games play perfectly under MESS.

    5. MESS/MAME sound (POKEY) support is superior to any other publicly available emulator for the 7800 (Including Prosystem).

     

    That being said, Prosystem does correct the few games MESS has problems with related to graphics and timing (But you have to tweak or ensure you have the right Prosystem.dat file for it). The ProSystem emulator does allow palette swapping, but outside of that has next to no video options or fine tuning outside of "stretched" and changing the size of a Window or resolution. It does have a prettier/easy to use GUI though.

     

    Neither the Stelladaptor, nor any other modern USB joystick interface will correctly work with genuine two-button Atari 7800 Proline controllers in any emulator. for dual button supporting games. The stick works, but you only get Fire Button A support. Yes, MESS and Prosystem allow for Two Button input, but you cannot use a true, original Atari 7800 controller for this purpose. You would need to either re-wire a real 7800 proline/joypad so that the buttons were truly independent, or use a Sega SMS pad or Genesis pad which don't need this kind of mod.

     

    Also - Neither MESS/MAME nor any other emulator in existence will work with an original Atari CX-80 or CX-22 Trakball in TB mode. This can only be done on real hardware. Trackball usage in MESS/MAME would need to be USB Windows Mouse compatible, or work wiht Arcade emulation hardware like a JAMMA harness, etc.

    It is not possible. There is no commercially available or homebrew USB adapter the correctly recognizes the independent fire buttons of the very few 7800 games that use them. On top if that, there are no emulators that would recognize the circuit anyway. You have two choices: modify your 7800 stick to be true independent firing like an SMS pad, or use an SMS compatible paf/stick instead.

    It's funny though, this thread does accurately pinpoint the late 80's NES era as the beginning of the Participation Trophy era of parenting. Games suddenly needed endings to help with validation issues.

     

    Boo hiss. Make the enemies faster and harder till I die.

    Staying in the topic of Donkey Kong XM specifically, would it be possible for someone to provide a parts list and schematic or wiring diagram to add the necessary Pokey chip to the cart to enable sound in the absence of the XM, if the old TIA sound can't be added back in?

     

    I'm pretty handy with a soldering iron and reading schematics. In the meantime while waiting for the XM to become available, this might be a fun project for those of us who like to tinker.

    [Ron Burgandy]Boy, that escalated quickly.

     

    Tep killed a guy. [/Anchorman]

     

    Here's a suggestion out if left field:

     

    Would be possible to add back in the TIA sound from the original 7800 DK, or maybe the 2600 DK which is less annoying, and have the cart detect whether the XM is present or not like Kenfused did with Beef Drop and Schmutzpuppe did with Froggie?

    Thanks again for all your effort. At this point I just chalk it up to the fact that some of the 7800 game devs were either just lazy, color blind, or were working on a dev station that had a different palette wihtout playtesting on a real 7800 console, because clearly with the YUV default you've made, a lot of them are correct, but a few are just WAAAY off. (and that is how they look on a real 7800 also)

    Ha!

     

    Well then this will send your OCD into flipping jumping jacks:

     

    Here's a screen cap of Pac-Man Collection using the last palette you posted, NTSC_R08EX_CPS, and then an Arcade PAc-Man screen cap from the latest version of MAME.

     

    As you can see, The red-push adjusted palette looks MUCH closer to the Arcade version than the default 7800 output does.

    Thanks. Yeah, been in and around for a while, just getter back into thing, emu-wise after a while away from it.

     

    I always wondered what the coders of Commando and worse, Tank Command were thinking with those color choices. Did they have really bad test monitors, or we're their Dev systems working in a different palette? Same could be said for Ms. Pac-Man.

     

    Maybe they were just really, really high. Lol.

    Tep, this is amazing!

     

    One thing I notice though, this plays great in Prosystem for Windows, but in the PSP port of Prosystem, The top half of the score lettering at the top is Chopped off. I'm sure this is a product of the coding of the PSP port of Prosystem, but it does look like there is some room at the bottom of the screen to move things down and it will all fit. Is there any way to do this in the a.78 file?

     

    Thanks.

    Those look fantastic! I really admire your work here Trebor.

     

    I'm partial to the Vibrant one, but I wonder if those are really how the 7800 coders back in the day intended for these to look, or if that's just how it ended up when the hardware department designed the compromised Luma and Chroma signal crossover for the 2600 and 7800 lines. I also really like the "red push" variants in your previous NTSC Final palettes thread. Particularly the EX R07-09. They seem to give the best representation of "good" color for what these games were intended to look like if you compare the 7800 ports to the Arcade version, or other contemporary console Ports (NES, C-64, SMS, etc)

     

    Specifically you can see what I'm talking about with Commando and Donkey Kong. If you use a palette with a moderate red push (NTSC_R08EX.pal for example) and then compare those to a screen shot of the Arcade versions of those games, and NES ports, the red push seems to be dead on to what the other version looked like.

     

    But yes, the YUV default and Vibrant palette files you've posted here are about as color-accurate as you're going to get with what a genuine 7800 really puts out. Especially a Compositie or S-Video modded 7800, which tend to skew even more to the green scope of things than original RF output.

     

    I've long wanted to add a tint control element to the Composite mod circuit in my 7800 so I don't have to tweak the Tint control on my CRT TV to get the 7800 games to look how I like, since I have other systems hooked up to it which are then negatively affected by the 7800 tint tweak. Unfortunately, I lack the electronics hardware knowledge to create a tint altering circuit for composite video, and there's even less useful information on the internet about trying to make one.
