Re: Why preserve video games?

I think a really simple reason is if you don't preserve game while you can you lose the opportunity to preserve them in the future. Just because some people don't see value in the media right now doesn't mean nobody ever will. The wikipedia article on "wiping" is pretty tragic https://en.w...

Tested on FCUEX 2.2.2 but no sprites on flashcard (solved!)

I am working on a little program to make test scroll across the screen based on a user entered string scrollnesmod-0.png This part works fine. I added in a little sprite field in the background on the scrolling text scrollnesmod-1.png which works fine on FCUEX 2.2.2 but when I try it on my flash car...

Re: Help horizontally scrolling more than 2 screens (solved)

Thanks so much that was it! Is (foobar),x in asm6 the same as [foobar],x in ASM3?

Help horizontally scrolling more than 2 screens (solved)

I am working through the advanced nerdy nights tutorial and I am able to get 2 screens of data scrolling nicely. However when I try and add in 2 more screens I run in to problems. I am pretty sure this is as I am drawing the columns off screen incorrectly as this is what I get. It looks like my code...

Re: Some sprites not displaying on Everdrive but OK on Emula

The singular most common reason for sprites to not work on hardware is failing to do the DMA as the almost-first thing in your NMI. And, in fact, trying running your demo in Nintendulator shows that DMA is being started at scanline 21 or 27, alternating every other NMI. You have to start your DMA b...

(solved) sprites not displaying on cart but OK on Emulator

I have a little homebrew rom which displays a scrolling text background with some sprites in a star field in the background. https://i.imgur.com/JOubzY3.png This works fine on emulators I use but when I launch the program on my famicom with an everdrive n8 everything works fine except the sprites in...

Re: List of techniques to fake 3D graphics with 2D hardware

It isn't an answer to your question but there are two examples of 3d effects in the High hopes Demo which I think are really good (I am sure everyone knows them already!). The first is the rotating rectangular cube. I have no idea at all how this is done. https://youtu.be/eQ-OcS2Gwvk?t=56 The other ...

Re: ppu corruption when trying to buffer nametables

Sorry, I should have explained that a bit better. Basically the desired behavior at this stage is pretty much what nesanimation.nes is doing. It buffers one nametable, once it is full, it flips which name table is being displayed and starts buffering a new one. The thing I am trying to fix is the pp...

ppu corruption when trying to buffer nametables

I have been fiddling about with ccovells anims demo for a while with a view to making a simple animation program but I have hit a problem. When using the rom the graphics are garbled so I checked in the ppu viewer in FCEUX and it looks like the PPU data is corrupt. I am honestly a bit stumped with t...

Question about smoothly handling multiple loops in asm.

This might be a bit of a silly / obvious question and I am not sure what the correct terminology is so it is a bit hard to google. Using asm6 something like this function1: ldx #$00 loop --do something-- inx bne loop function2: ldx #$00 loop --do something-- inx bne loop Will obviously give me a &qu...
