Osmeroid wrote Thanks fellow !!! Osmeroid wrote Not for now, but I plan to add the select Background/Playfield colour feature in the next version (and to add support for PAL / SECAM colour palettes) As you know Playfield colour is define by the write address COLUPF. So I'll just add the numbers of the colour used for the background and the playfield in the header of the code generated. It will looks like that: ; Colour used for the Background (COLUBK) = #$00 ; Colour used for the Playfield (COLUBK) = #$66 This may help, but you know that you can change the COLUPF and the COLUBK value every scanline or even many times in the same scanline. Take care, Chris

New version available to download. What's new : - Changed graphic core : smoother mouse drawing. - Negative Playfield function added. - Undo function added. - Re-Positionning Playfield graphics on screen using arrows added. You can find it here (jump to the Tools section) : http://khryssun.free.fr/programming.html Hope this'll help. Chris

Hi, I wrote this utility to draw Playfields for the Atari VCS 2600 and to save the pictures as datas code ready to be included into VCS 2600 programs. This editor is WYSWYG. It supports Asymmetrical, Symmetrical and Mirrored Drawing modes Learn more or download it in the new "VCS 2600 PROGRAMMING" page of my Website : http://khryssun.free.fr/programming.html It's located in the Tools section. Hope this will help.

I never read this article before. In my point of view, it is EXTRA-TERRIFIC (in the scary meaning)

Thanks fellow

The Dig Source Code Archive link into the System > 2600 > programming section doesn't work. Is the site dead or has it moved ? Maybe a mirror exists ? Any info is welcome. Thanks

Just wondering how many are really active on the forums... Anyway Congrats to AA

My top 5 : - Howard Scott Warshaw : Yar's revenge, E.T. and Raiders of the lost ark are my favorites games. - John Van Ryzin for the amazing H.E.R.O. - Rex Bradford for the wonderful SW: The Empire Strikes Back - Carla Meninsky for the Great Star Raiders - David Crane for all the good games he programmed too

I always played for the High Score so far. The Continue option is an evil temptation

Really nice work Krytol. Congrats. lol Moycon, I think yours was made quickly. It seems you use the copy/paste functions very well

Nice work for this April Fool's joke Albert

A modification can be done on the 7800's mainboard if robot tank doesn't work with it. I don't remember where I found the schematics (maybe it's still into the Atari Age Message Board Archives) but I've done the modification 2 years ago (as I remember it's just a resistor to remove). I made an avanced version of this modification with a switch button located at the back of the 7800 so I can enable/disable the resistor. and it works fine.

If you want to build it yourself, it's easy and cheap : http://khryssun.free.fr/joyadapter.html Note : This adapter works with joysticks only. Paddles, Keyboards and Driving controlers won't work. But it works with all games/programs/emulators that use the standard PC joystick Port.

CWshredder has solved my problem, but as you all suggest I think I'd better switch to a more secure browser. Thanks for the info Duane, I didn't knew MyIE2. It Looks good BTW: You made a really nice job with your "To What Degree Do You Love E.T.?" pages ! Well I've got a little secret to tell about E.T. I've posted it here : http://www.atariage.com/forums/viewtopic.p...p=558507#558507

Well I've got a little secret to tell about E.T. The easter egg I've hidden I my VCS Simulator's game "Rays' Quest" was about E.T. As I made it near impossible to find ... I think I can tell now what it is : When doing several short right and left moves with the yar pressing the fire button at the left bottom of the room located just before the Left symbols deposite room, it makes E.T. appear and crossing the screen (and gives extra lives too).

Thanks fellows, I'am gonna keep a close eye on the situation. I'll try CWshredder and/or maybe I'll install a new browser such Opera, I think it's a good one.

Why don't add a "Set Atariage as your default Start Page" link at the top or the bottom of the main Atariage page ? Just got that idea because as a lot of people here I'm surfing the web a lot and I'am bothered with some sites (lottos in particular) which change the default start page of my browser without asking. I've got to go to the option menu of my browser to chage the default starting url manually everytime. I'am sure I'am not the only one in this case, and I think It would be usefull to add a "Set Atariage as the default Start Page" link to the main AtariAge page so we'll just have to click on it to redefine The AtariAge web site as the default one. What do you think about it

Yes, big vs small ship's diamonds was already known as a label variation.
