I just use SPRDEF in Vice 128. So much easier.

Hey everyone. You can always hop over to my Facebook and catch me there, but you probably already guessed that I've thrown in the towel for KZfaq, as others have. However, I will still be posting videos on my Facebook, which has been growing a lot lately. My apologies if you expect another video, but I don't have the energy and patience to edit a video for several days, post it, and still watch the numbers decline. Anyway feel free to reach out to me there. I'm pretty active and will answer your questions. Still working on the project when I have time, so at least that isn't dead. Take care! It's been great! i may plan to make a departure video to be fair, but even that is up for debate. Please do visit my Facebook page below. I care about all the subscribers and everyone who still watches the channel. I'm still here, just doing different things these days. facebook.com/profile.php?id=100063890751740

Steve I want to let you know I really value your basic tutorial series. You have shown a lot of really great stuff here that is really useful for designing a game. You are definitely a great C64 teacher. Thanks again

Update: It is quite possible I may not produce another video for this series, but my Facebook is alive and active these days for this project. Too many other commitments are consuming more time with keeping up my skills for my Web Developer role these days. It takes a lot out of me. So when I get time for researching things, I try to update the game. The world is different for me now, and I apologize if this small channel meant that much to you. So I really don't know if this project will continue here, as I can't make any promises.

Nifty to use the spreadsheet to build your lookup tables, but you should rather use macros in your assembler.

I must be a very stupid person, because I really don't know what the hell you're doing, I just wanted to play the game but I don't know how to load the game files on Vice emulator, I didn't know it is very technical about typing those command lines. WEW!!!

I never owned a C64 but programmed quite a lot in BASIC back in the days. This took me back. Great video!

The decimal number system is from 0 to 9. 9 - 0 = 9, so that must mean it is base 9 and not base 10. Just messing with you. Always add one because the range is inclusive. So for the screen memory, it would be 2023 - 1024 + 1 = 1000 distinct character positions. In another video you said there are 255 possible values in a byte... that is also incorrect. The possible values are 0 to 255, and 255 - 0 + 1 = 256 possible values. If you were just learning it wouldn't be a big deal... my concern is that these videos are being put forth as instructional, so it's more important to get it right.

If you are trying to increment the border color, here are two ways to do that... The hard way... 100 forx=0to22:readn:poke828+x,n:next 110 sys828 120 data 169,32 :rem lda #$20 130 data 133,251 :rem sta $fb 140 data 169,208 :rem lda #$d0 150 data 133,252 :rem sta $fc 160 data 160,0 :rem ldy #0 170 data 177,251 :rem lda ($fb),y 180 data 24 :rem clc 190 data 105,1 :rem adc #1 200 data 145,251 :rem sta ($fb),y 210 data 32,228,255 :rem jsr $ffe4 220 data 240,242 :rem beq -14 230 data 96 :rem rts The easy way... 100 forx=0to8:readn:poke828+x,n:next 110 sys828 120 data 238,32,208 :rem inc $d020 130 data 32,228,255 :rem jsr $ffe4 140 data 240,248 :rem beq -8 150 data 96 :rem rts

This was a fun exercise - thanks for the inspiration. Here is a short program I wrote to output the character set in color... 100 ifpeek(863)=255then120 110 forx=0to35:readn:poke828+x,n:next 120 sys828 130 data 169,147 :rem lda #$93 140 data 32,210,255 :rem jsr $ffd2 150 data 162,0 :rem ldx #0 160 data 142,32,208 :rem stx $d020 170 data 142,33,208 :rem stx $d021 180 data 138 :rem txa 190 data 157,0,4 :rem sta $0400,x 200 data 41,15 :rem and #$0f 210 data 208,2 :rem bne +2 220 data 169,12 :rem lda #12 230 data 157,0,216 :rem sta $d800,x 240 data 232 :rem inx 250 data 208,240 :rem bne -16 260 data 162,8 :rem ldx #8 270 data 160,0 :rem ldy #0 280 data 76,240,255 :rem jmp $fff0

Been hammering out refining some animation techniques (water) in the project. I also fixed a scrolling issue. Be sure to check out my Facebook to see more current updates.

7:32 I'm not seeing the Opcodes listed in alphabetical order. Also, there are a couple of errors on that page: • The Opcode for $16 says ASL aa, Y but is actually ASL aa, X. • The Opcode for $BC says LDY aaaa, Y but is actually LDY aaaa, X. 11:26 While in Immediate mode, why do you keep typing ?CHR$(147) every time you want to clear the screen instead of just pressing Shift+Home? Isn't it easier to just open the Vice Monitor and assemble ML from there, or is the goal to not rely on it?

I downloaded the project zip file from your article on c64Brain website. When I run "Main.prg" in the latest VICE, it shows garbage on the screen and the borders are all messed up (it doesn't crash though).

I’m late to this tutorial some 35 years… 😑

Wow, thanks! Brings back loads of good memories! The joysticks are still confusing to configure (lol) but great program. I remember a game called "Factory" by Hesware - that was certainly ahead of it's time. This rocks! :)

YOU FUCKING LIAR

Super!

Is there a way to decrypt text adventures on the C64 so that you can read what the commands (strings) are? The code usually shows up but it's a scrambled mess in both Action Replay cartridge monitor and Cheat Engine.

Where have you been? Been a while, man.

How to modify file extension.asi ?

Heads up everyone. Now that I got some busy stuff sorted out in my life recently, I'm attempting to revisit the next tutorial series soon. This time though I aspire to use Kick Assembler which requires a lot of code revision on my part, and will delay a little further since I lost the original extraction I created for Kick a while ago. Hang in there. C64 Brain in is dead. Just took a vacation.

ASMR pure thanks.. what program do you use to write asm in your Atari ?

what a beautiful syntax..

Great video

Thank you for making this video. I will come back to this ASAP to develop along what you’ve presented. I’m very grateful for this tutor and the level of in-depth example and explanation you’re giving. Thanks again. 👍

I ran the prg and get the following: "?out of data error in 10". I checked to ensure I correctly entered that line code.

anyone here in 2023 😂, btw it still works for anyone wondering if you are using Gta IV downgrade (which u should be using)

Mod name ?

please get to the point. way to much superficial crap..

Videos que valen ORO!!!!

Este video vale ORO!

Gran trabajo...gracias!

I ried now the link but seems outdated. Could you send a new one? Or could you make is public maybe?

Gracias por tan valioso aporte a la COMUNIDAD ATARIANA MUNDIAL...SALUDOS!

Commodore BASIC v2 does not have a restore statement. Damn you Jack!

1:15:54 I remember this tutorial, from the blue book, I have it typed and saved on a cassette.

Hey how can a sprite detect a specific character?...when the detect register only detects a collision has occurred?...example: a ladder vs some other character and how to make a sprite distinguish between the 2 or 3 character sets?

Hi, the membership is still updated?

I would like to how to print out any program that I might have type in, I tried to find out put I am coming up short. Any help would be welcome, thank you.

only 31 thumbs up?? thats sad because this is great brain food

Thanks good video

👍

Thanks this is great

Your Discord link is probably expired or invalid. If is expired you need set time expire for never. Great video from you hobby

I wish this kind of videos were available when I had my C64 and started some basic programing (before internet age). I really enjoy watching these.

Sprites...now there is a word I have not heard in a long time 🙂

really great work! a part from ther scrolling, how can i make the man walnk an the ground and stop if a obstacle is reached? how is the tecnhique?

Well done!, keep up the good work! I am following whenever I can!

Where was this 40 years ago when I needed it? I've gotten back into 6502 & my old 800s for fun and also teaching my kids (and others). Not just the basics of lower level work but also many concepts which were critical back then are still valid and useful, from efficient memory usage to understanding the CPU and other hardware. Thanks for an interesting video; DLIs were always a PImyA.
