This thread's topic is clearly derived from another thread's topic, as are many threads here.

Oh, right, content.

    AND AL,0x0F

    ADD AL,0x90

    DAA

    ADC AL,0x40

    DAA


I wrote some code that runs on the boot sector of a floppy disk and loads a 320x200 image directly to video RAM, complete with palette. That section right there is part of the error handler, which ran far more times than it should have as I worked around a BIOS bug.

I think I want my next project to involve an endless triple-fault loop. (Okay, it won't be very useful, but it will make me feel better.)

I could not possibly agree more.

I've compared 6502 to MIPS III and I have decided both are much better than x86.

MIPS is pretty great. Actually compared to 6502 I'd say MIPS has a huge advantage in the convenience department alone. The problem is that, as far as I know, there really aren't any simple-but-useful MIPS-based platforms like there are for the 6502 and family (like the C64, NES/SNES) and so on, so I never really had any reason to mess around with it that much outside of the college course where I first learned it.

Of course my knowledge of actual MIPS-based platforms is pretty slim so

I actually wonder if I could pick up Z80/680x0 at some point. Might look into it.

6502 would probably be the most useful of 8-bit types, though...

6502 and its variants are pretty simple, mostly. Most of the real work is learning the details and intricacies of whatever platform you're trying to code for and using that knowledge to make something useful/nonbroken

I'm gonna start learning how to program music for the 65816. Problem is, the NSPC isn't totally consistent throught the games D:

The 65c816 has very little to do with playing music on the SNES. All of the real work is done by the SPC700. (It's similar to a 6502, and the official documentation makes perfect sense if you understand 6502/65c816 programming.)

So wait, not only are you looking at the wrong chip, you're using pre-written software? Pff. That takes all the fun out of it.

Ok, so what I should've said is I'm going to learn to program music on the SNES.

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
