    They have lead in the lid I think, or something else that smells very metallic at any rate.

    I was surprised at how heavy and not-cheap the console felt, but this explained that.

     

    So if its back in stock, did they fix anything?

    [Final] Monkey King

    The code wont compile (missing goto's)
    The invicible icon in score_graphics.asm is different than shown
    You don't need pfvline here it's already in the branch clearing stuff
     ; pfvline 8 0 11 on
 ; pfvline 24 0 11 on
 
 gosub clearP0left
 gosub clearP0right
 gosub __sprite_color : drawscreen
 gosub clearP1left
 gosub clearP1right
    you don't need all these joy0fire clauses in the if statements
    you already tested that in the first if statement
     ; power up activation
 if !joy0fire then __skipfire
 ; if joy0fire && player0score > $0 then gosub __firesound
 ; if joy0fire && player0score = $a then gosub __slowdown : player0score = $0 
 ; if joy0fire && player0score = $b then gosub __killbranch1
 ; if joy0fire && player0score = $c then gosub __livesplus1
 ; if joy0fire && player0score = $d then player0score = $0 : _invisible0 = 1
 ; if joy0fire && player0score = $e then player0score = $0 : gosub __mkbranch1
 ; if joy0fire && player0score = $f then player0score = $0 : _invincible = 25 : _left_right{6} = 1 : _F0 = 25
 
 if player0score > $0 then gosub __firesound
 if player0score = $a then gosub __slowdown : player0score = $0 
 if player0score = $b then gosub __killbranch1
 if player0score = $c then gosub __livesplus1
 if player0score = $d then player0score = $0 : _invisible0 = 1
 if player0score = $e then player0score = $0 : gosub __mkbranch1
 if player0score = $f then player0score = $0 : _invincible = 25 : _left_right{6} = 1 : _F0 = 25
    You can flatten the killbranch routines a little (but you still need the labels for the individual routines
    since you're calling them to setup the playfield)
    killbranch1
   player0score = $0 : bally = 100
   gosub sprite_color
   if left_right{4} then clearP0left
clearP0right  var1 = 1 : var5 = 1 : var9 = 1 : var13 = 1 : var17 = 1 : var21 = 1 : var25 = 1 : var29 = 1 : var33 = 1 : var37 = 1 : var41 = 1 : var45 = 1 : return
clearP0left   var0 = 0 : var4 = 0 : var8 = 0 : var12 = 0 : var16 = 0 : var20 = 0 : var24 = 0 : var28 = 0 : var32 = 0 : var36 = 0 : var40 = 0 : var44 = 0 : return
    Since you allways call the sprite_color routine before drawscreen you can move drawscreen into sprite_color and get rid of a bunch of calls to drawscreen
    and you can do it with a tail call optimization (you need the prepended dot because that's what bB assumes
    ie "goto drawscreen" becomes "jmp .drawscreen" so you need to declare .drawscreen)
       if startgame then sprite_color_return
   ;Check if player is invisible
   if invisible0 then invisible0 = invisible0 + 1 : COLUP1 = $C4
   if invisible0 = 200 then invisible0 = 0
 
   if invisible1 then invisible1 = invisible1 + 1 : COLUP0 = $C4
   if invisible1 = 200 then invisible1 = 0
 
 
 
   const .drawscreen = drawscreen
 
sprite_color_return
 
    goto drawscreen
    I think you're calling drawscreen a lot more than you need to
    Since your pfreads are with constants, just use the screen variables
      ; if pfread(9,1) then return
  ; if pfread(25,1) then return
 
  if var5{1} || var7{1} then return

     

     

    Strange it worked when I uploaded it, but I was in a rush so maybe I messed up :S I'm stuck on a mountaintop on a island until the end of the month (looking at the Sun, or trying at least), but maybe I can get bB to work on my Mac. All my saves are on my home PC though, so I can't access them. I'm hoping that its just the .asm files that are wrong. I'll get back to you asap.

     

    Thanks for the upgrades also, this should shave off quite some bits again. :)

    Astronomer 2600 now has a patch that you can earn

    in Atari 2600

    Posted

    Today the boxed version of Astronomer came out in conjunction with the Orionid Meteor Shower (Take a look outside if you can!), to celebrate this we have released a patch that anyone can win. If you have the cart or the boxed edition then shipping is free otherwise you need to pay a small fee for shipping. The patch comes with a special letter.

     

    To win you need to get a score of 20 in any game mode and send in a screenshot to the email in the flyer. Feel free to post them here too!

     

    To buy the game go to ‘packratvg.com’ and use the Order Form, for the rom go to the astronomer thread.

    Homebrew Boxes

    in Atari 2600

    Posted

    There are etsy pages that print one off boxes if you give them a template. For the ones that don't have a box you could ask the creator and see if one can be made for people who really want them. The place that I used to get an Astronomer box is decent but there were jpeg artifacts on it and the resolution was not the best. But unless you watch it very closely it looks great.

     

    IdK how Al feels about printing sold out AA boxes, so I'll warn against that unless he says yes.

    more than one missile question

    in batari Basic

    Posted

    You can probably hack it in with assembly somehow depending on how the game looks. Like if you have a space invaders like setting you could set NUSIZ0 to different values above scanline X and to something else below it. But that would limit the move space of your character. (Not sure if you can change something like that after like half a scanline if you want the game to be flipped 90 deg.)

     

    I'm not an assembly wizard like others here, so they can probably call out my BS or give a magical script. But I think any possible fix will be very specific so explaining your game might help.

    custom fonts for bB, all-in-one score_graphics.asm

    in batari Basic

    Posted

    I stumbled across a strange effect with this .asm. If you move the font to be all the way on the left. e.g.

           .byte %00000000 ; TINY
       .byte %11100000 ; TINY
       .byte %10100000 ; TINY
       .byte %10100000 ; TINY
       .byte %10100000 ; TINY
       .byte %11100000 ; TINY
       .byte %00000000 ; TINY
       .byte %00000000 ; TINY

    Then it will give a strange error for the most right score digit, inserting an always active row of pixels. I'm using this in conjunction with KarlG's player_score kernel and he also thinks its probably some kind of glitch with the lefter most pixel not getting erased.

     

    Is this a known issue? I could really use the extra pixel to align my fonts with.

    I tried to reach out again but nothing unfortunately. I hope that you guys get some answers during the PRGE!

    I really like this console TBF but it should play everything..especially new home-brews.

    Yars revenge 'safe zone' effect in player sprite?

    in 2600 Programming For Newbies

    Posted

    Is there a simple way to get the yars revenge safe zone effect into the player sprite? I tried pointing the color to some random adres Banks, but most don't do anything interesting and don't give a psychadellic number. The best I found was playfieldpos as it loops between 1-8.

     

    In my current code it also colours the entire player in one solid colour. I imagine that a better way is possible where every row has its own color?
