I ment the HEX address of the file. I found it though. I wanted to correct the timer to an actual second. If you wanna know what it is search the value 18 thoughout the file. It's over the 1000th address I know for sure. But now another question, how could I make the second digit loop back to the n...

You know, Nintendo wrote an interesting document on converting NES games to GB. You oughta track that down and see about doing the same but in reverse.

doppelganger, It would seem to make the most sense. Perhaps to avoid copyright issues, I should make people have to get a hold of the CHR data themselves. Other than that, it seems like it's a pretty long task. ^_^ How long did it take you again? :D EDIT: Though the RAM addresses are almost complet...

Well, good luck with that. I don't really mind if you use smbdis.asm to do smb2j, just as long as you give credit where it's due.

How are you going to organize this? Will it be by the files themselves?

It's a waste to have more than 120 pixels for vertical resolution?

Exactly how is this?

Are you trying to make a CD player out of the NES or the game cartridge?

And haven't you already been down this road before?

Pfft. That looks fourth-rate, amateurish. Anyone with 5 minutes and a copy of mspaint.exe could do that. Just give me the file, and I'll write in light-grey text on transparent background, then rotate 180 degrees and paste.

And I'm not even sure those numbers stand up to scrutiny either.

Yes. It effectively shuffles around in memory which sprites get used for enemy, fireball, air bubble, block and misc objects so that one sprite object never stays in either a low or high-numbered sprite set for longer than a frame. The sprite offsets get shuffled every NMI (long, long after the DMA ...

No, I don't think the original programmer(s) intended for there to be two outcomes from one set of demo data. On the other hand they probably also decided it wasn't worth the trouble of fixing to break deadline.

There is a three-frame delay on the "second" demo that isn't present on the "first" demo. This is caused by the interval timer continuing to run between the two demos. When Mario touches the goomba and dies on the "second" demo, the master timer control freezes all time...

I get the feeling we missed something. <goes over thread again> Are you referring to this: How would I edit it so that the fireflower doesn't use h-flipping for the right half of the sprite? I really want to know this and I think an example of how to change something would help me a little. or somet...

Actually, I'm curious, what did you do to add the labels? Did you just work them in manually, or did you have a program that added as you disassembled the code? Additionally, what do you think of using a code data logger to help disassemble? I worked them in manually. The only things I used were a ...
