6502.org

After reading many tutorials, I'm at something that I haven't seen in one.
See the attached photos. image2 is the sprite and image1 is how the sprite looks on the screen.
What am I missing?

Assuming this is a Commodore 64, you are missing the "MOB Multicolor Sel" bit in $D01C.

You need to get hold of the C64 Programmer's Reference Guide and read the parts that are relevant to what you're doing. In this case, page 442. That whole appendix will tell you everything you need to know about C64 graphics.

Back in the Olden Days we didn't have tutorials. We had the PRG and a willingness to experiment, and that was more than enough.

Moreover, the manuals written back in the day (especially by Commodore) were specifically intended to be a standalone, comprehensive, digestable guide to everything standard that the machine could do, written for enthusiasts wanting to learn home computing from scratch. They're made exactly for this sort of situation.

The piecemeal tutorials online are often written by people who are trying to learn themselves, and are often incomplete or written from misunderstanding. Even if they're written by somebody who knows their stuff, they usually gloss over the "well known" parts and don't establish the basics as well as the manuals do.

The user's guide and PRG are available in multiple places & formats online, including archive.org. (Page 135 is the explanatory section with examples, pg 442 is the reference)

Thanks guys. And thanks for your patience too.

(It might be a good idea to put, say, [C64] in a topic title if it's a C64 specific topic. There are a host of 6502 systems and projects of interest here, and many of us are not primed for machine-specific questions.)

Noted.

You can go back to your head post and click "Edit" and change the title. I did it for you.

Thanks Garth. I'll remember that next time.

I will say that there doesn't seem to be any good, major Commodore 64 specific forum out there anymore. Lemon has terrible moderation, allowing tons of misinformation; CSDb is semi-private and intended for those editing the database; and other major one I know of is non-English.

So do feel free to continue posting 64 topics, especially as it relates to 6502 concerns. There's plenty of Apple II discussion and other platforms that occur here as well.

I'm certainly happy to see platform-specific conversations here, so long as they are 6502-related. It just helps to have a bit of context, and it's a sign of mutual respect too, to acknowledge the breadth of the 6502 world: Acorn, Apple, Atari, Commodore, OSI, Rockwell, Tangerine, and so on - as well as homebrew systems, consoles, and so on.

(The other thing is that this is a technical forum: it's not a place for advocacy, platform wars, flames, or belittlement. Being platform-neutral, or platform-universal, helps that.)

I didn't care for lemon64. That's why I made an account here. And going by the help I've received I made the right choice.

Going to chime in on this. Lemon64 USED to be my Go-To location for all things C64. But it's become a cesspool of jerks over the last few years. I was recently the victim of one such jerk over there (it's happened several times). So I no longer will use Lemon64 for anything other maybe some game information. I won't contribute to it any more.

AtariAge is a good place most of the time. That's where I go for Apple, Tandy, Atari and TI stuff.
I like this forum for hardware and general purpose 6502 although many people on here are familiar with the C64.

This place (and AtariAge) have great moderators.

I will mention one more place that I go often for C64 related stuff (and some misc), and that is Shallan50K's Discord.

Discord might not be your thing (if you're offended by foul language that is...lol). But those guys are amazing and bend over backwards to help you out. I can't recommend them highly enough.

Anyway, sorry to take this OT. The C64 deserves a good forum home. Maybe we could get a new forum added here and start pulling some of the *NICE* people away from Lemon?

DanielS,

I'm going to promote Shallan one more time. I wanted to mention he has an excellent YouTube series on making a game from scratch on a Commodore 64.

I've been following his videos for a while and they are very informative.

Anyway, just FYI if you're into C64.
