This is probably a stupid question, but for what reason would a processor be forced to use a certain instruction width? (Well, THUMB is either 16 or 32 bit, but cannot be larger than that). ...I was just about to say about I'm just confused as to why there would be a 16 bit instruction that contains...

I recently started programming on an STM32 microcontroller (ARM Cortex-M0 processor) for college and was naïve enough to try programming in assembly. There's little way to work with immediate numbers, and the limitations always seem to change heavily based on the instruction (sometimes it's an 8 bit...

Writing the Super FX code like that looks like it would have been hell.

Okay, I see now. I wasn't expecting whatever is mapped to the start button to enable you to modify the values.

What are the controls? I can move the cursor around, but I haven't been able to make anything happen beyond that, unfortunately. It might be a good idea to include a readme file at some point for if you plan on distributing it outside of NESDev. Fantastic work, by the way.

I agree that b. would not work. I have yet to meet someone in person who has heard of NESDev.

Metal Slug 2 says "hi"

Well, for example, if you wanted to add more graphics data for another sprite animation frame between two others, you would either have to fit it somewhere where it would no longer be intuitive, or you would have to insert the graphics data and move everything after it, but then the pointers pointin...

I got to thinking about this recently... With a system where tile data is copied to VRAM from program ROM, the assembler will update all the pointers if data is inserted or removed, but it obviously can't do that here. It might be worthwhile to create a program to parse through the text file cointai...

Probably Ninja Gaiden for me. It's difficult for me to choose an NES game with the best music because a lot of it starts sounding similar to itself due to how inflexible the sound hardware is, imo.

Wow, thank you for compiling that information! It's mildly unfortunate a lot of this information isn't available outside of source code anywhere. And I'm really impressed that it's in time (segaretro actually specifies line buffers and pixels per scanline), as I've never seen any sprite pixel per li...

Haven't been able to find this information anywhere; does anyone know how the Super Scaler series of arcade systems (Hang On, Outrun, X Board, Y Board, System 32) actually drew the scaled sprites? I would guess the systems are framebuffer (not just linebuffer) based, but System 16 gives information ...

Wow, that's a great resource! I found the TV I was interested in ("RCA" 204F24) but sure enough, it appears to have an all together chip. The only doubt I have is that there's a sync out; what is the neck board responsible for?

I figure I'll just open it up and look around; I presume it would be pretty obvious. I also imagine whatever chips being used will have part numbers written on them with a data sheet hopefully online somewhere. I wouldn't think a company would make new chips for every TV model?

Yeah, shoot, both of mine are from about that period so they might not be eligible.
