Re: Starting VIC-20 unexpanded-project UEFA European football championship 2024
Hello there again! I am still there. But I was/am very busy with my work. Now, in the long weekend, picking up this project again. The chaining of programs keeps me worrying: "that means POKE45,PEEK(174):POKE46,PEEK(175) with a follow-up CLR will also do the job and won't need to be corrected a...

Pretty neat! And now I know all about the linewrapping INPUT-bug.

Re: German Magazine - Type-Ins - Compute Mit
My computer refuses to download the zip, because of the firewall.
But there is an archive of this magazine: https://archive.org/search?query=subjec ... ute+mit%22
Very nice. But I understand that most members here don't talk German.

Re: Jeff's VIC 20 Book
I just ordered a copy from Amazon. I can't wait to get it! I ordered a spirald one! :mrgreen: It can help me a lot during programming. Now I am looking up things in PDF-books. I bought myself a spiral version for Christmas. Thanks again for making this book, Jeff! THank you, all! Your support is ve...

Re: VIC-20 joystick - which is the real way?
I saw a ping-pong-game with paddles. That is a step further in coding.

Re: Corrupt end of basic program
I am pretty sure it is not a bug in VICE, because it happens too often and I can't find anything about it on the internet. And no, I never use the @-replace-option when saving the program. My programs always begin with OPEN 15,8,15,"S0:program":CLOSE15: SAVE "program",8 And I sta...

Re: Corrupt end of basic program
What tool did you use to create the program file in first place? This error is typical for a BASIC program file that for whatever reason was saved with a missing last byte . By itself, the SAVE command of BASIC does not produce that problem - but once a BASIC program is loaded that has been produce...

Corrupt end of basic program
This happens to me in VICE regularly: When I saved a Basic program to disk or tape and I load it again I see, when I list it, a line of garbage with a strange linenumber at the end of the program. When I look it op in the monitor I see that the last line is not ending with three zero-bytes. A Basic-...

Re: New BASIC game for the unexpanded VIC: TINY QUEST
This is very nice! I didn't solve it yet, I am now in the castle watching a tower to the west. I was developing an text adventure for the unexpanded too for Christmas (Christmas adventure). The target was to get a christmas tree. But I had an accident on the way, so I develop it later for Christmas ...

Re: Starting VIC-20 unexpanded-project UEFA European football championship 2024
It is not necessary to do the POKEs to 47..50 and 51..54, provided you follow up the POKEs to 45/46 and 55/60 with a CLR statement. CLR will set the pointers in 47/48 and 49/50 from 45/46 and the pointers in 51/52 and 53/54 from 55/56. Sorry for my late reply, I had to work this week. Now it's week...

Re: Starting VIC-20 unexpanded-project UEFA European football championship 2024
Lessons learned: Loading longer programs from another program. I made a menu-program for this system from where I load other programs. I knew this would go wrong, because the VIC doesn't update the pointers to the memory where variables and arrays are stored and this will corrupt the program loaded....

Re: Recommendations for VIC-20 assembly tutorial, tools
I am learning assembler with this book: Compute! Machine language for beginners. Written by Richard Mansfield. You can download this book for free. It is for the 6502-chip and among onthers, the VIC-20.

Re: Starting VIC-20 unexpanded-project UEFA European football championship 2024
I know, and that is the interesting part of it. The match-table is what bothers me. Integers take two bytes of space and as you look at the table, most variables fit in a single 8-bit byte. Looking at the date, the tournament takes place from june 14th to july 14th, so I can nibble of the monthnumbe...

Starting VIC-20 unexpanded-project UEFA European football championship 2024
This summer 24 European countries will fight for the championship football (In the US it's called soccer). 51 games will be played in 10 stadiums in Germany. I started programming a system on the unexpanded VIC for following the tournament. It will be a memory-fight, but that is what I like. First I...
