    Working off of what Nabuko78 started, I finally corrected the NTSC Pallette in Prosystem.

     

    I suppose these hex values can be ported to MESS as well.

     

    I will be updating the PSP7800 source files and compiling a new PSP7800 with these as the default later tonight.

     

    Inky is finally Light Blue again!

     

    THIS IS THE FINAL VERSION.

    I REALLY hope in the next release of ProSystem the colors are fixed so that all of us can be sure of the colors we are seeing in the emulator. :(

    ProSystem supports custom palette files. Is there a more accurate one floating around out there anywhere?

     

    If you're using Prosystem version 1.2, it already has the latest Nabuko Palette as it's default.

     

    It's as close as anything has come to accurate yet. But it's still not perfect. Something the light blue/green/teal/light green part of the Prosystem pallete is messed up, as you can see from this and the color of Inky in Pac-Man Collection.

     

    I wish I knew which values to work on, I'd have already fixed it.

    Chopper Command is not a game that has trouble with the 7800.

     

    the only games that *rarely* have trouble playing on the 7800 are:

     

    Dark Caverns 2600

     

    Activision Decathlon 2600

    Space Shuttle 2600

    Robot Tank 2600

     

    even less often: Pitfall II.

     

    any other problems you encounter are most likely a bad cart, bad 7800 console, or both.

    Better sound - fixed the crackly, buggy sound from all the previous versions. sound quality is vastly improved.

     

    JUST ADDED!!! - Final NTSC color Palette, fixes problems with blues/greens - Inky in Pac-Man collection.

     

    Added an Animated Icon, for the XMB, with 7800 BIOS/Impossible Mission Gameplay video.

     

    Changed In-Emu artwork.

     

    Trimmed down the in EMU menu system, renamed some choices to make more sense. Removed annoying redundant "Push X twice to Exit" silliness.

     

    Originally coded by ZX-81 at DCEMU (I worked on it with him, but he did most of the work porting it to PSP), updated by yours truly.

     

    Enjoy.

    an updated DK would need to be like 128k for sure. Quite the undertaking IMO.

    sure, but looking at the quality of stuff like Beef Drop, B*nQ, Pac-Man collection, Space Invaders, Froggie - it's entirely possible.

     

    I waited 21 years for most of those to show up on the 7800. another few months or a year or two to fix the issues with Donkey Kong wouldn't be that big a deal. It's just a matter of hoping that someone who knows how to do this would be willing to and having the time to do it. If I knew how, I would have done it already. Unfortunately, I don't. I know a bit about coding for the PSP, and some SDL stuff, but that doesn't really apply here. and only enough to be dangerous or bugtest/make corrections. Not enough to code something from scratch.

    So 7800 DK has no 4th screen,so what,neither do alot of other versions.Besides the sound,its pretty damn good IMO.

    But that's not what this thread is about.

     

    Now that we have dedicated coders working on filling in the blanks in the potential 7800 library, this is certainly one of the more often requested ideas.

     

    I'm not interested in "good enough". Not now that we've been spoiled with Pac-Man Collection, Beef Drop, B*nQ, etc.

     

    It's like driving a Ferrari, and then settling for a Chevy Chevette.

    Sorry,didnt mean to disrupt, the original post said 7800 DK doesnt have the 4th level,whether or not that doesnt have anything to do with this thread?,It was posted,and everyone seems to complain about the missing level in 7800 DK,which is silly cus most DONT have a 4th level,thats all.

     

    The Original had the 4th level. Even the 8-bit/5200 version had all 4 levels. The 7800 is more than capable of having the 4th level. Shit, Beef Drop has like 4 more levels on top of the 4 original levels in the arcade version of Burgertime, and the 4 original ones are pretty much arcade perfect.

     

    There's no reason NOT to have the 4th level, or possibly more, except sheer laziness.

     

    The only thing that's silly is settling for something that's half-assed, when a complete version is more than possible.

    Also, is there an A78 version of Centipede TB? I would love to play that hack!

     

    I'm not sure why you would want it since none of the 7800 emus support the trackball.

     

    Mitch

    If you have a CC2 or the ability to make a cart/eprom you can play it on a real system.

     

    An A78 file won't work for either of those you need the raw BIN file.

     

    Mitch

    yeah, but you know what I meant.

    You would need the source code to do this. It is next to impossible without it. Even with DiStella. :(

    ... unless you're talking about wtiting it from scratch...

    I figured as much -

     

    It's got to be around somewhere. all these other source codes and stuff popping up.

     

    how were you able to do so much with Ms. Pac-Man, not having access to the source?

    This was discussed in the other New/Homebrew thread, but as suggested, it needs it's own discussion.

     

    Donkey Kong for the 7800 in it's current form, in my opinion, feels like a 75% work in progress version. It still lacks the 4th screen (conveyor belts/pie factory) and the sound and music are atrocious. the graphics are decent enough though, as faithful as I believe the 7800 would render.

     

    As there is now a healthy and growing hacking/homebrew scene around the 7800 these days - is there any way we can convince one of you oh so talented coders (Kenfused, PacManPlus, schmutzepuppe - we're looking at you) to finish what was left undone?

     

    It doesn't seem like all that much work, really. But then - I don't know much at all about coding for the 7800.

     

    Anybody?

    Centipede TB is in fact complete. It was coded by Kenfused, who also coded Beef Drop (burgertime).

     

    I could probably make centipede tb carts, but don't have the equipment to make really good labels yet. I was hoping to hear feedback if it works on both TB's in trackball mode or if I need to add more code for that. I would also probably want to add something to the title screen to distinguish it.

    One thing I thought would be cool to distinguish it from the Atari original version - remove the border box from the playfield. It always bugged me that they put that there when it really serves no purpose.

    Which trackballs did you want it tested with?

     

    Mitch

    It works great with the original white-ball CX-22, and the black-balled CX-80 "looking" one that is actually a CX-22 also that Best Electronics sells.

    Centipede (with Trackball support)

    Frogger

    Q*Bert

    these already exist.

     

     

    Huh. Sweet. I didn't see them on the 7800 game list. Where could I go about aquiring these games?

    http://www.atariage.com/forums/index.php?act=Search&f=4

     

     

    Ahhh.... The old search linky. Clever. Anyhow, before you posted this here is what I figured out...

     

    Centipede TB - There was a thread about it, but it seems it went nowhere.

     

    Frogger - Apparently it was almost complete, but I see no confirmation of a finished product.

     

    Q*Bert - Also looks close, but again there is no confirmation that it was finished.

     

     

    So I would still like those to be on my list since they aren't likely done.

     

    Q*Bert is complete and can be bought from the Atariage Store. It goes by the name B*nQ so as not to offend copyrights.

     

    Centipede TB is in fact complete. It was coded by Kenfused, who also coded Beef Drop (burgertime).

     

    Beef Drop is also Available in the AA store.

     

    Frogger is at release candidate level. It's complete in every way.

    So I posted my short list of wanted games in this thread to be added hopefully to the 7800, given the fantastic hack/homebrew scene that has developed in the last few years.

     

    But just for proper placement, I'll start a discussion about it here as well.

     

    My most wanted:

     

    Crystal Castles

    Spy Hunter

    Donkey Kong ARCADE(with all levels and better sounds)

    Gyruss

    Stargate/Defender

    Time Pilot

    Zaxxon (possible hack of Desert Falcon)

     

    by the way - in case some of you hadn't noticed, the thread I linked above is PacManPlus' awesome new homebrew version of Space Invaders for the 7800, that is nearing Arcade perfection, as it moves along.

     

    I know a lot of you would like to see non-ports, or original games. But I'm really just an old arcade buff, and the 7800 dose such a great job with these types of games.

    I know this isn't a request thread, but Gorf and SI are so similar in gameplay, I'd rather see Bob dedicate his time to something entirely different, if he decides to hook us all up and code up another masterpiece for the 7800.

     

    I'd love to see any one of the following(or really all of them ;) ) ported to the 7800:

     

    Crystal Castles

    Spy Hunter

    Donkey Kong with all levels and better sounds

    Gyruss

    Stargate/Defender

    Time Pilot

    Zaxxon (possible hack of Desert Falcon)

    Another question concerning the RF modulator; once all 4 pins are cut, is it essentially useless? I'd like to be able to remove it so I can have a bit more space to perform the mod.

    I found that trying to remove the box tends to be a giant pain in the ass. It's got 4 mondo solder joints on the bottom of the board holding it in place. but I did snap the board sticking out of the back of it off to make the mod easier to work on.

    I'm also getting really tire of pulling the metal sheilding off the mobo, and replacing it every time. what a pain in the ass that is.

     

    Just toss it. Once you get it modded, you don't really have any need for it anymore. I actually did this with some of my other systems and they work just fine.

     

    Is this true? puppetmark?

     

    I suppose it makes sens the metal sheilding was to prevent interference from getting in the the RF... anyone?

    *Update*

     

    I fixed the POKEY Audio. All I had to do was run a wire from the top of C10 to the audio jack. I actually made the connection by running a wire from C10 to where the audio jack connects to the resistor I added for he audio.

     

    Here is a picture of the wire:

    post-9166-1215482665_thumb.jpg

     

    Here is a close up of the connection at C10:

    post-9166-1215482712_thumb.jpg

     

    Here is a close up of where the POKEY audio meets the audio out:

    post-9166-1215482793_thumb.jpg

     

    Also, Changing R15 did very little to teh brightness of the video, BUT changing R11 from 39K to 47K seems to lower the brightness some. I didn't have to turn down the brighness as much and it seemed to help the aura effect on bright objects.

     

    Here is where to find R11:

    post-9166-1215482949_thumb.jpg

     

    I am glad I got this to work. I hope others decide to try this. Its really not too hard and the results are well worth it.

     

    Thanks again to everyone who helped.

     

     

    Just did this. AWESOME. The glow/Halo around bright/white objects is gone. perfect.

     

    I'm also getting really tire of pulling the metal sheilding off the mobo, and replacing it every time. what a pain in the ass that is.

    The early Donkey Kong machines allowed you to slip a flattened drinking straw along the edge of the coin door and rack up free credits.

    Lots of machines would take "slugs" too, the little circular cutouts from Electrical Junction boxes. They were almost exactly the same weight and dimensions as a US Quarter.
