Great! This works!

Then to Pong Robot stops moving. I thought of adding/subtracting #$0: f1fe adc #$00 f200 sbc #$00

Hmm... the game freezes if I change this. The routine seems to be used by other parts of the program, too.

The common typo! How often have I made it?? Would it be possible to bypass the routine with: f1e3: jmp $f202 f1e6: nop ... make the "Pong Robot" invincible?

Great, thank you. In the next days I will tinker around with the code in Stella to see what happens if I change the mask. µP/Stefan

Hi, I am searching for a specific function in the "Video Olympics" code: The AND mask that is used to "diffract" the Robot's paddle from the vertical ball position. I found a hint to this in a quote from Bogost's/Montfort's "Racing the Beam": (p. 39–40) Does anybody know where this AND mask is located within the code? (And is there a disassembly of the "Video Olympics" code with comments anywhere on the internet?) Thanks! µP/Stefan

I'd like to order one of the "RZ Pen-B". µP

Please add me to the order list.

Thank you so much for your helpful hints!

noone?

Hi, for a lecture about the Atari VCS game "E.T." I need a photography of the cartridge's circuit board (upper side with the ROM chip). Does anyone know where I can find one or can anybody take a picture of it and post it here for me? THANKS! µP
