The code looks correct to me. Are you sure that this is the part that's not working properly? Have you debugged the code and traced through it instruction by instruction to verify where the problem is? BTW, are you sure that Temp is in ZP? Pointers will only there, and NESASM has been known to sile...

I had an Eureka moment thanks to you guy's. The pieces are falling together. Also my apologies for creating confusion by using "Background sprite" instead of "Background tile". So here is my new code (which I still have to try): ; declare variable(s) Temp .rs 2 ; reserve 2 bytes because of 16 bit LD...

Hello everybody, For some while, I've been trying to find the background tile number of the tile based on the location of my sprite. I've been reading (and learning) in these threads: 8x16 sprite is really a 16x32 pixel image? Object collision But I still have some trouble figuring it out and fittin...

The link on your site for the Zapruder code is not working. Fixed. Pin Eight just moved to a different provider, and a few files didn't get copied correctly. Thanks, going to take a look to see if I can learn some extra stuff. Thanks to everybody for the input ! I implemented the code and the balls...

Thanks guy's, I'm going to try both solutions to learn the advantages/disadvantages of both. My own Pong clone runs physics at 120 Hz, but that's because objects can move up to 20 pixels per frame, fast enough to have an object move "through" another in a single frame. Individual half-frames still u...

Hello everybody, many of you will know the Pong like game tutorial over at NA. After a long break, I am now continuing those lessons by creating my own pong game. I created a nice playing field where my ball bounces around. I also managed to add the functionality of increasing the speed. But here is...

Ik dacht: ik zal nog maar eens posten in deze thread aangezien ik mijn interesse in NESdev opnieuw heb opgevist. Ben momenteel bezig met de beginselen: Ik kan al een bal mooi laten bouncen in een kader, allemaal met een mooie achtergrond. Ik kan de snelheid van de bal aanpassen, en dit ook weergeven...

Note that after each write to $2007 you don't skip over the other compares, so even after you've found your number and drawn it, you will still compare for every possible digit after the one that got written. All compares will fail and nothing will get drawn until the #2, but since you don't specif...

Hello everybody. Thanks to bunnyboys nerdy nights over at NA, I've been doing a attempt at homebrewing. The tutorials started with how to make a PONG game. I started from there and made a closed area where the ball keeps bouncing around. The speed of my ball is adjustable (1-6). I can adjust this sp...

Instead of making a new thread I thought I'd ask it here. I get the following error from my willem programmer (PCB 4.5C): Error at 0x000300 Chip = 0x00 buffer 0X18. I'm trying to program 27C512 Eproms. The dip switches and the jumper (only 1 on the image) were all set according to the image on the s...

From the site: Are Game Copying Devices Illegal? Yes. Game copiers enable users to illegally copy video game software onto floppy disks, writeable compact disks or the hard drive of a personal computer. They enable the user to make, play and distribute illegal copies of video game software which vio...

Is that bad or good

Hallo, zijn er hier nog andere nederlands sprekende leden? Ik ben zelf van België. Ik heb in de andere thread gezien dat Hap nederlands spreekt maar die leekt niet zo blij met de NESdev international thread

Kzie er naar uit om over NESdev dingen te praten

Hey everyone. I wanted to post something in the usual "Introduce yourself" topic by I can't seem to find one here so I made a new one. :D My name is Kenny, I'm 21 years old and I live in Belgium, Europe. My hobbys are collecting/playing nes games and soccer. The reason I registered on this site is b...
