Wanted: 2600 Donor Carts

[Wanted: 2600 Donor Carts]

I always though you mold them by yourself! maybe it's time to think about homebrew plastic injection. there's a guy at opcodes games who made them for Coleco... or maybe somebody will think about all theses E.T cartridges six feet under the ground...

[Best Joystick for Atari 2600]

the zipstick or a good old speedking are probably the best joystick, too bad nobody make it anymore http://www.retroscene.co.uk/prodimages/joysticks/m/zip_stick2.jpg

[Is there a game manual template?]

you mean the format of ye old ATARI's manual? or the color chart according to the language?

[The Titlescreen Kernel]

Many thanks for this kernel, I guess it will be useful to pin it or create a master Thread where all the available kernel will be displayed (I mean no support thread, because it will be difficult to read, but more like a tool box; maybe in a near future we will have a lot of kernel available)

[Looking for a post by batari about wriggling sprites]

256Ko.. I wish we can access that..

[L.E.M. Lunar Excursion Module]

very funny game.

 

I just wish I can access to asm part to understand how the titlescreen was made.

[PAL 50 in Batari?]

Thank you. it should be ok, I just hope the flicker will not be too awfull on our real TV

[PAL 50 in Batari?]

Can we do PAL50 games with Batari?

 

As far I've understood, I must look at sound side, because frequency is not the same, but is there anything else I missed?

 

please be kind about my english: it's not my native language.

[joyfire with sound]

The problem in a nutshell, is that if missile0y<=240 then you're always skipping the bit of code that increments your sound timer and turns off the sound when it reaches 2.

 

If you move that bit of code above your missile0y check, so it's executed each frame, then everything works out...

 

*** EXISTING CODE

 if missile0y>240 then goto skip
 missile0y = missile0y-2:goto drawlooping
 
skip
 if joy0fire then missile0y=player0y-2:missile0x=player0x+4:AUDV0=4:AUDC0=3:p=0
 p=p+1
 if p=2 then AUDC0=0

drawlooping

*** NEW CODE

 p=p+1
 if p=2 then AUDC0=0

 if missile0y>240 then goto skip
 missile0y = missile0y-2:goto drawlooping
 
skip
 if joy0fire then missile0y=player0y-2:missile0x=player0x+4:AUDV0=4:AUDC0=3:p=0

 

ooh thanks, the logic in programming is merciless..

[joyfire with sound]

Try adding a "=0" to the end of your if statement.

 

Without it "p" will be some value from 0-255 when the fire button is pressed.

 

Thanks, it's working better but I'm still trying to understand how it works: because when I set if p=2 then AUDC0=0, the sound stay as long as the missile is on screen, very strange

test sound.bas

[joyfire with sound]

I'm trying to add sound in a little game,

 

if joy0fire then missile0y=player0y-2:missile0x=player0x+4:AUDV0=8:AUDC0=4
 p=p+1
 if p=10 then AUDC0=0

 

:/ I though the counter will be in frame, but it's too long, it plays during 3-4 seconds, so I wonder what is my mistake.

 

any idea?

[Sci Fi Quest]

is it 100% batari? or is it ASM?

[Sci Fi Quest]

very cool!!!!

 

I like the gameplay

can't wait a PAL version

 

how did you make the boxes? I wish i could do beautiful bow like this one...

[Is there a boxes maker tool?]

Hello, I've found an Atari label maker and I was wondering if a tool for making Atari boxes was available?

 

sorry for english mistakes, it's not my native langage...
