Underball

same as above. Final* version now. *until I find something else wrong with it....

Updated one last time. Palette file and sources updated.

If you don't mine me asking...What was changed? -Trebor One of the Red/pink values was off. If was showing as yellow, and the colors in One on One were wrong. I made a typo when I was adjusting it in the Hex editor.

I think it might be time to set up separate subforums for homebrew by console type, and brand. Lots of stuff here isn't really Atari homebrews, even though this is a predominantly Atari site. Kind of confusing.

Exactly. Mine is the same. Model 3, no expansion port - not a single problem. Robot Tank, Space Shuttle, Decathlon, none of the "suspect" games have ever given me trouble. It also depends on the cart itself, as most of those games had several iterations. The end result is that your chances of getting a bum system that won't play the suspect games is pretty rare.

WRONG. One on One runs just fine, provided you have the most updated prosystem.dat file that corrects the timing issues in One on One. Here it is: This one also fixes the problems of: No pokey sound in BallBlazer allows Missing In Action to sort of work has update hash entries for the latest version of lots of 7800 homebrews ProSystem.dat.zip

Just RE-UPdated. It was a little off on a few. Now it's FINALLY* right....I think.

Just RE-Updated it. There were problems with the palette in the PSP port, all fixed.

how do you do a level select, other than starting on the first one?

updated - see above.

Just did this - Also (Sorry bob for taking your SI thread way off course, but it's kind of relevant) - Look here Missing in Action is now fully playable in Prosystem. Woo Hoo!!! I promise - back to Space Invaders only talk from now on.

So as I was poking around the prosystem.dat file, seeing if I noticed anything peculiar - I realized I didn't have an entry for Missing In Action, even though I knew it didn't work right in Prosystem. After a bit of testing - I figured it out. Here's the proper entry: [017066f522908081ec3ee624f5e4a8aa] title=Missing in Action type=2 Pokey-false controller1=1 controller2=1 region=0 flags=2 Turns out it needs "type=2" because is a 145kb rom, and it need "flags=2" because it uses the same weird ass banking scheme as Kung Fu Master. I've attached the file for those not wanting to edit it manually. Plays perfect now. Without this entry in the prosystem.dat, the game is correctly identified as type=2, but it doesn't automatically identify the proper flags=2 banking scheme. UNFORTUNATELY - I just discovered taht once you pass the first stage and go to "bridge of fire" you get nothing but garbage. bummer. ProSystem.dat.zip

That hash isn't valid for all versions of Beef Drop. the Hash for the final demo from July 18th 2006 is: [7adbd2cec2e2cbc1e0ad237778ee46b9]

You should really check out the latest version of PSP7800 I posted in the 7800 porum on this site. ZX has apparently abandonded it, or just has too many things going on, but I updated the sound and color palettes recently. It runs a whole lot better now. It would be creat is someone could figure out the sound problems in the Prosystem source. I agree that Beef Dop and even Ms. Pac-Man sound like ass, on every version.

Done! Updated the attachment at the top. These are direct NTSC values from a video-modded composite out 7800. You may notice that all around the colors are punchier and more colorful than using a real 7800 with RF out. RF tens to mute a lot of the tonal qualities. ALSO - attached here is the updated ProSystem source files for the Updated NTSC palette, if someone wants to incorporate them into an official release or port them to MESS, etc.

As I said, tonight I'm going to hook up my recently A/V modded 7800 to teh composite video capture port on my PC's webcam - and try to get a good screeshot. that way - if it's accurate, I can open the screenshot in Photoshop and use the eyedropper tool to get the actual HEX values for each color bar. The way the Palette files work - in any HEX editor - set the HEX display to 20 lines vertical, by 48 lines horizontal. Essentially this lines up the hex values with how they are displayed in the 7800 color Demo. Each color is made up of 3 HEX strings. So for Black the HEX value is 00 00 00, or the first 3 HEX editor boxes. And so on down the list. Photoshop can give you the exact HEX value of a color in an image file with the eyedropper tool. So just open the accurate screen shot, check the HEX value for each of the 256 colors from the colored boxed in teh 7800 Color demo, and then type them into the palette file in the HEX editor. The pain in the ass part is putting them into the actual palette.cpp file int eh Prosystem source files so I can update PSP7800. I have to open the Palette.CPP file in Wordpad, and the new Palette.pal file in a HEX editor side by side and transcribe them manually, as the Prosystem source pallete file has the "0x" before each HEx value, and a comma after each, plus the layout is different.

DUDE! Hi-Res Old School Half-Assed Invaders.

Beautiful..that would be excellent...But let's continue this elsewhere as I don't want to lose the focus of this thread or hijack it from the attention Bob's Space Invaders deserves. -Trebor done... http://www.atariage.com/forums/index.php?showtopic=128755

updated above.

Possibly, it could just be my 7800. I do believe there is a "pot adjustment" for the 7800. And I do have one of the original (84) models with the full expansion port. The maze always appears deeper, darker, or/and more saturation than any of the palettes I have ever seen. From what I recall, the color is extremely similar to the snapshots on Mobygames by Servo (Posted earlier)....Just not as "red"...slightly more "pink". Which of course, all the above can be expected with the NTSC standard. Which is why I really would love to see an NTSC palette developed for Atari emulators, the same way it has been done for Sega and Nintendo systems. Regardless, like I said earlier from what I can initially see, your latest posted palette is the best that's out there. You should have it submitted to the ProSystem and MESS authors. -Trebor What I'm going to do tonight - is try to get a screen shot of the 7800 color demo from the real hardware/CC2 through the A/V port on my PC. That way I can open it in Photoshop and get the actual HEX values for each color bar from a real 7800, and then update them in the palette file. Up until now I've just been winging it, and going eyeballs only. Using the actual HEX values from a screenshot from a real 7800 with composite video out (like mine) might yield closer to perfect results.

It looks real good so far Underball. Probably the best palette yet from the few games I was able to quickly review... I am at work now. Although, Ms. Pac-Man's maze still appear too light Pink/Pastel and should be darker (Or at least more saturated) in color. -Trebor I'll have to check it against the real thing tonight. I'd never noticed Ms. Pac-Man's maze being that dark before.

*crossing fingers* I *think*, I may have finally gotten it about as perfect as it can get. greens look good. blues look good. none of the existing games look wonky. Inky looks good. Shields look good. test it and let me know. NTSC_test_palette.zip

To me the bottom one looks closer as far as the shields shade go.. I agree...and I am presuming that is the color (Or very close to what) Bob sees on the 'real thing'. I am trying to figure out which matches closer to the real thing (AKA Atari 7800 connected to television). Both screen shots are from Post 182 images. The top one is using Underball's latest palette. The bottom is using the palette based off of the work done in Stella. Which ever one sticks closer to what Bob sees on the real deal is the palette I want to base my opinions on. -Trebor Trebor - can you post this palette file that has the work done recently in Stella? I have a feeling the proper colors are somewhere between that one, and what I've been fiddling with. Your greens look good on the sheilds, but I got the value for "BB" looking right with Inky in Pac-Man collection. Now that I have the process for changing the values down fairly easily, It shouldn't be too hard to get it right. **NEVERMIND - duh - you posted it on the last page. It's defintely inbetween that one and the NaBuko. NaBuko's is too green on the BB and surrounding colors. the Stella one is a little too pastel, and the grass in Commando ends up being a sickly teal/aquamarine. Hopefully I can get a decent one by later today.

Why is your metal sheildings covered with the cocaines?

Yeah, I missed the green shades. here the FINAL corrected version. I compared them directly with the Color Demo running on my CC2 on real hardware. It won't get any closer without a X-Rite Calibrator and a colorimeter. Prosystem_NTSC_Corrected.zip
