Defender_2600

...5200 have many barrels, fireballs, etc. ... The 7800 and NES are even limited in the number of barrels, fireballs, etc. ...Hmmm.. ...Here a comparison 'up-to-date' :

So generalizing ...high resolution BUT poor palette, low number of color, low number of _small_ sprites, abundant flicker ... ...or low _horizontal_ resolution (with the advantage of wide pixels) and huge palette, high number of colors, high number of _large_ sprites, no flicker ... Therefore, again: the 7800 320 mode (320×240) shows square pixels (pixel aspect ratio: 0.9 NTSC and 1.0 PAL) and can replicate the correct aspect ratio of the arcade graphics. Asteroids Deluxe, AstroBlaster, Astro Fighter, CrazyBrix, Dungeon Stalker, Frenzy/Berzerk, Froggie, Moon Cresta, One on One Basketball, Pac-Man 320 / Ms. Pac-Man 320, Rip-Off, Scramble, Space Invaders,Tower Toppler: these 7800 games are all made in 320 mode! The NES with 256 horizontal pixels by 240 vertical pixels display wide pixels and therefore wide sprites/tiles compared to arcade graphics / 7800 320 mode . Same goes for ColecoVision, Sega Master System, CoCo 3, etc., for these systems the pixel aspect ratio is approximately 1.2 NTSC and 1.4 PAL. On the other hand, the 7800 160 mode (1.7 NTSC pixel aspect ratio ) can display a large number of color and an enormous number of sprites on the screen, each sprite/ tile can use from 3 to _12_ colors plus transparency _without limits of size (great flexibility)_ and flickering absent. The 7800 features a broad palette of 256 colors, in layman's terms it means having more than a dozen of blue, green, orange, etc., that you could use it to design night scenery, forests, sunsets, etc., therefore the color depth can be considerable despite of the wide pixel aspect ratio. The NES features a palette of just 53 colors, 8x8 tiles / 3 colors, 8x8 or 8x16 sprites / 3 colors. In conclusion, each system has its strengths. Darryl, putting words into action, you watch carefully the following images and 7800 Mess screenshots , play 7800 Ms. Pac-Man 320 _exclusively under Mess_ (you will see _little_ black box around the sprites, ProSystem creates an _enormous_ black box as artifact!) and download my 'round' 160 Ms. Pac-Man (Graphics Hack) (WIP) with proper lipstick and nice bow!

Lynxpro, since in the beginning it was your initiative to ask the Trak-Ball support for Centipede Frameless hack, I've just invited you in our private conversation. You're welcome. Marco

And in case may be of interest to try a version with alternative graphics, recently I made a 7800 Centipede hack in which I removed the frame/border around the playfield along with some other graphical update. Kenfused's Trackball support is included (Thanks again, Ken! ). http://atariage.com/...cade/?p=3257450

I would like to see greater use of the 7800 160B mode ...

Indeed, all these beautiful photos tickle one of my old temptation. Nice project, Bob!!

Merry Christmas Bob and to every one here!

No, just 208 lines for graphics and status / score.

Therefore... the EGA standard (1984) just has more colors than the CGA standard (1981) ... The 7800 160 mode (1.7 NTSC pixel aspect ratio ) can display a large number of color and an enormous number of sprites on the screen, each sprite/ tile can use from 3 to _12_ colors plus transparency _without limits of size (great flexibility)_ and flickering absent. And without tricks. For instance, 7800 Ninja Golf (Dragon Boss) :

...I found this mockup in my hard disk :

Arcade Sound: 1x Atari POKEY @ 1.512 MHz

I'm happy that you like. Regarding the POKEY support..."Maybe down the road"... : http://atariage.com/forums/topic/214447-colecovision-vs-7800-vs-5200/page-7?do=findComment&comment=3257175

Yes, I have purchased two PCB's! Simply, I thought the question was referring to the release of the game (ROM) in electronic form. KevinMos3 Rampage (Graphics Hack)

Not yet, the player sprites graphics is still a work in progress.

Believe it or not, Perry has made the 7800 Donkey Kong remake without having the source code!! Simply, he is a alien man born on the planet Krypton...

Thanks for your interest, guys! Here the .a78 file and .bin file with signature valid. Centipede_Frameless_tb_v2_(WIP).a78 Centipede_Frameless_tb_v2_(WIP).bin

Here some updates, I have edited the graphics of the damaged mushrooms and the graphics of the poisoned mushrooms. Curiously, in the original 7800 version the sprites of the poisoned/damaged mushrooms change the color and graphic detail instead in the arcade version they change only the color so I have corrected this difference. I've also updated some colors/details on the title screen. Centipede Frameless _tb_ v2 (WIP).bin

Therefore a first look ..

Really ingenious!

Blue Azure does a great (new) job of disassembly, he is a generous guy. And in the Atari (VCS) era a variation of the game is a new game!

Spoiler please! Splendid work, Illya!

7800 Crossbow deserves a complete updated graphics with characters / sprites redrawn from scratch, updated tiles and new colors. I would like to work on it so I'm giving a first look at the graphics / rom , however it will be a very long project because currently I'm already working on some 7800 projects.
