What websites did you use to learn asm?

Hacking-cult =P

I don't know too much but I know enough to do what I want...

 

I didn't really use a website, but I learnt what I know off other people. Some people seem to learn better with someone explaining things to them rather than reading plain text. Sonic Hachelle-Bee started me off, then I learnt a lot just by studying a disassembly. Finally, Ultima taught me how to use a few of the more complicated instructions. Maybe you should find some knowledgable people with time to help you who can help you learn. You might find it easier than reading a guide.

 

Motorola M68000 Programmer's Reference Manual. It's all you'll ever need.

 

I haven't seen Lewis in a while. Devega was down for the longest time, then it came back up but the forums had vanished. Sucks, too, as I was a regular there (and could also post news).

 

I learned it by tweaking stuff.

 

First I read DRX's guide in Hacking-Cult. Then I've noticed he makes a lot of mistakes (specially he forgots to reenable the interrupts by putting "move.w #$2300, sr") and started to check the real things by myself.

By the way, a tutorial is always better when you start, and a reference when you learned the basics.

 

I use this:

I can't remember where I found this.

 

*I* make mistakes? :P

You can only use 'move #$2300,sr', without the size suffix (it's always a word-long write). Besides, the 'mistake' you pointed out is not really a mistake, since I do *not* always use interrupts, you know.

Btw, my guides really need a major rewrite, they were written over 3 years ago =P

 

drx, have you taken your guide down? I don't see it.

That's what I get when I post while half asleep. Thanks.

 

Believe me, I had to do a lot of things from scratch because some of your routines had something wrong. And I suggest to check your initialization routine, it's pretty obvious you took it from somewhere else :P In fact, the first thing you clear you put "clear some VDP stuff". It's the VSRAM. Etc.

By the way, I put move.w to sr because of custom, nothing more. It gives the same result, right?

 

ASM-to-Hex code reference. Now I understand this website now and it's realy helpful.

Sorry for bumping!

 

It would be a good idea to put a list of places to visit for learning ASM as pinned.

 

Like I said, my guide was written in 2003, when most of the code there were no nifty disassemblies around, and my Megadrive knowledge wasn't that complex. Remember, at that time, the only thing I had was 68kd and long hours of analysing code =P Most of the things I put in my 68k guide was 'cracked' by me, hence some holes in the whole thing.

And no, I didn't get it from 'somewhere else'. That's a lame attempt.

 

I've got this old textbook on M68K programming that I need to finish reading some day =P
