One typo is in 270, the POKE at the end is supposed to be for 7698. That fixes the ; and shows a start countdown. Perfect, thank you. :wink: Edit #2: Munged some other place for the additional char. That is NOT the proper listing anymore, but modified line 170, 290 and 300 to use the init and use t...

Hi! I made some changes to lines 260 and 350, so they're not actually typos. 260: I changed to GR=0 because with -1 you were doing an extra lap. 360: I added PRINT"{HOME}GIRI"GR so that it displays the number of laps at the beginning of the program, whereas before it was displayed after 1 ...

I take advantage of your kindness to ask for further help. In another program, called Grand Prix, some details are not displayed as they should. In the screenshot I attach, you can see that the colon and the traffic light (top right) appear redefined. It is likely that there are some typing errors o...

Okay, I solved it. I also changed lines 840 and 870 because they drew the plane landing badly. I then added a change so that the plane, landing, was drawn correctly. Original line: 910 printleft$(h$,h+4)"{right*9}{space*12}":return My change: 900 ifh=15thenreturn 910 printleft$(h$,h+4)&quo...

Thanks. Should I also change lines 840 and 870?

Last bug: when the plane lands it is not drawn in full. It seems like a line is missing.
Once this is fixed the program is fine.

Yes! Thank you both so much!
There is one more problem: the UFO never shoots down the plane. The instructions say that once the plane is hit three times it falls to the ground, but this does not happen.

Hello to all.
I have typed a listing from an Italian magazine, but I find a problem: the joystick does not work.
Can you help me?
I attach the original listing, PRG and TXT files.
Thanks in advance and happy new year!

Rimosso.

Ottimo, grazie per la miglioria. Un caro saluto!

Grazie a tutti! :) Sarebbe stato carino fare un programma simile a "Season's Greetings" per C64, ma ci vuole un maghetto della programmazione in assembly, e io di certo non lo sono. Sono fermo a LDA, STA, e tutto finisce lì! :mrgreen: Comunque l'intento era quello di creare un'atmosfera na...

Thank you. However, I finally decided to do the program without a snowfall effect. You can download it here. It will however be useful for future programs. Thanks again, and happy Sunday.

Some of you have a snow-effect routine for VIC-20 similar to this video (starting from minute 0:38)? It can be in BASIC or machine language. I tried to do it in BASIC but the final effect doesn't satisfy me.
Thanks in advance and good weekend everyone!

Perfect! Here's the bug!
It was a typo in the magazine, as can be seen in the attached file.
Thanks so much to both of you.

Hello to all. I have typed a listing from an Italian magazine, but I find a problem: the joystick does not move the little man. I point out that the listing is correct, checked several times. I also checked the original version of Compute!'s Gazette magazine, and it's all right. Can you help me? I a...
