Re: Starting VIC-20 unexpanded-project UEFA European football championship 2024
This doesn't work for large programs. I already pointed out in the thread " Corrupt end of basic program ", that copying 174/175 to 45/46 is problematic. Actually, it only works immediately after the program has been loaded - the KERNAL load procedure places the address behind the last lo...

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....

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...
