Alrighty. I've gotten an NSF included in my program and I've gotten the play routines and everything. One problem I'm having involves sound effects and music. I can play music fine, though I need to reset the sound registers when the track is done in order for sound effects to work. Obviously, I can...

I mentioned on another site that I'm using page $0400 for sprites instead of $0200 and this seems to be working. The real trick now is to get sound effects that I already have play correctly while music is playing.... They do play, but they sound all weird.

Well, the NSF certainly does cause problems unforeseen... Although I don't know what I could do other than not using one. Is there any easy way around all this or is it probably going to be a lot of trouble to find out? I've heard of ways of doing music without using NSF's, although they sound quite...

Alright. Things have been fine for a while, but in chat I have learned about sprites and conflicts. This has only come into play now that I've been trying to add NSF support to the game. What basically happens is that some graphics don't show up and others are "moved over". I've even gotte...

Alright, I've been trying to use a guide to simply play the NSF song I made up as a standalone rom. http://www.nullsleep.com/treasure/nsf_cart_guide/ Basically, I did it to the letter, looking up all the addresses in the NSF header and whatnot. I'm just wondering, is that guide erroneous or are ther...

Well, the only reason I'm using NESASM is because I could get it to work and because it's my first program ever and the step-by-step tutorial on how to set things up was useful. I took an assembly class last semester and we used MASM in there, so a lot of assembly-related concepts are similar here. ...

Demo updated. The link up top is the same, but with a newer file. Features a lot more stuff and a result screen after 20 levels. See if you can get a perfect 20/20! All I need to do is get random numbers and possibly some music in there (maybe better sound effects too) and try fixing the vblank bug.

Alright. We figured it out. I had used up my first 8KB bank from $C000 to $DFFF. I just needed to declare a new one starting at $E000

No problems now.

Right now, the only "fix" I have done is to just comment out a bunch of my .db statements. Mainly the text ones in screens I don't need to see. I also got rid of that .org $C000 as that makes it compile and not work. Heh. So... Could it be that I have way too many .db's in there? I have qu...

The error: Out of range, bank offset > $1FFF! I'm assuming this means I have too much code or something... But I thought I had a lot more space than what I have... A whole bunch of the nes rom has 0's in it... One "fix" I've attempted: .bank 0 .org $C000 That is basically above my constant...

Site may have been down. It works now.

Bug: The first frame that each background is scrolled incorrectly. Possible cause: You are turning on rendering during draw time. If so, here's a fix: Wait until vblank time to turn on rendering. I know about this. I actually have tried doing that "wait for vblank" using a variable counte...

very nice, i managed to beat the computer once. do you have plans for 2-player support? Thanks. The computer is easy to beat when you know the algorithm. :) As for 2 player, I don't know. I don't know if it'd be worth it. I'd have to modify some of the flow of the program for it too. The main big t...

SPEEEEED!

So awesome.

Even though it's a rom hack, what about an NSF rip from Rockman no Constancy?
