Either I'm insane, or I just saw a post that said "Someone almost set up us the bomb." What is "the bomb" anyway? And I'm pretty sure it was supposed to be "Someone almost set us up the bomb."

What you said though about running out of sprites is certainly interesting. With 128 sprites you have quite a situation when you still run out of them. Like I said, this could have easily been avoided if they had used the 16x16 and 32x32 combination. There is a part in level 3 of that game where th...

Although I'm not adding anything to the subject, have you ever seen Super R-Type? It's quite possibly the most inefficiently programed game I've ever seen. So much so that when the game actually goes to normal speed, (when there are absolutely no enemies on screen and you are not pressing the fire b...

yes maybe u understand the basic grasp now of how to implement jumping, but you should NAIL IT DOWN with a demo. The fixed point math reference tepples made is extremely important on these systems without floating support. It's a useful way to use the bytes/words as a cheap decimal fractional notat...

I actually did make a working demo of a character jumping, (using the walker code) but it wasn't very useful because I basically just did bcc on the sprite y variable so that if it went far enough down the screen, it would "pop" it above the line. I don't remember exactly how I did it (I'm...

Super FX adds sprite overdraw. Look at the title screen of Yoshi's Island. Each of those buildings revolving around the center of the island is a quadrilateral drawn by the Super FX coprocessor, and those are sent to the PPU. What you are calling added sprite overdraw is really just a buffer they s...

Since your still hear, I am just going to ask who or what is Neviksti? I've heard the name several times and I just searched the name on Google and I found a website called neviksti.com and this is what it contained... There really isn't much here at the moment. You may be looking for this: SNES Har...

I was about to ask you as to why you seem so angry until I actually noticed that you were the one who made the tutorials. I really am an idiot... :( The tutorials I were bashing the most weren't the ones you wrote. I'm honestly not making this up (I swear!) when I say that the tutorials you wrote we...

Eh, I don't see what's holding you back. Why not try out my tutorials? They take you step by step.. They'll hold your hand more than I will .. lol Are you talking out the ones at superfamicom.org? most of the tutorials there only show you how do things like load data to vram and scale a bg in mode ...

Now to reply to koitsu monster post... Don't worry I'm not angry at you. :wink: (Why would I be anyway?) You seem to do a lot of complaining about the state of programming (particularly in assembly) in these parts, and I get the impression you are very frustrated with the nature of the beast. Is tha...

I don't see when they built the SNES why they didn't make it so when the x coordinate byte got past 255, it would overflow into the 9th x bit, but maybe this would have been too hard to implement? It does overflow into the 9th x bit. This bit just happens not to be stored contiguously with the rest...

There are automatic disassembly tools; some expensive (IDA Pro); some free (nescom, nesrevplus); some not fully automated (e.g. FCEUX+disasm6) Based on the titles of these (I haven't looked them up) it looks like they are for the NES, unless the work for both. I have heard that coding for both syst...

Again, the only reason I am posting this under SNESdev is because it is pretty much my "comfort zone". :oops: I remember looking at a discussion where tepples was showing an example of how to optimize code for the 6502 and the 65c816 and psychopathicteen said that those were the kind of &q...

What is "hioam"? I have never heard of this term before. If this is a term you invented, please don't do that. :-) "Hioam" is just the 2nd sprite table that is 32 bytes long and contains the sprite size bit and the 9th x bit. Edit: you beat me to it! :wink: He is wondering if an...
