Re: Project: Chip's Challenge for NES
If anyone's interested, I've kept the source code here: https://github.com/Jaffe-/chip-challenge I haven't worked on it since 2011, when I lost interest and belief in the project. I've thought about it now and then since that time, and I think I can make a better effort now than I could back then. W...

Re: The NESIZER
You might be able to fix those phase reset clicks by using the APU sweep units. From what I understand there can be 3 different sequences: when the high bits increment, decrement, or stay the same. Wow, I searched around about this problem and came to the conclusion that I couldn't do anything abou...

Re: The NESIZER
A JMP opcode is sent each time a sequence of APU updates is done. It is immediately followed by the STA zero page opcode, so the 6502 jumps to $8585 and then continues executing STA. I initially thought it was unnecessary, as it seemed to work fine without jumping, but that was until I tried disabli...

The NESIZER
Hi :) It's been a while since I was here last time, but I thought I'd post a project I've been working on for the last year or so: The NESIZER. It's basically a little synthesizer module using the 2A03 (or a 2A07 or Dendy clone). It has buttons and a display for programming patches / sounds and batt...

Thanks, I must admit I never even thought of doing that! The game is still fully playable at 30 fps, but the jerky movement gets quite tiring after a while :/ I do however feel optimistic about eventually adding music to the game if it's acceptable to run it at 30 fps. The same demo as before is ava...

I would also like to see this finished, but I simply don't have the time to work on it now. When I'm working on something programming related I need to work on it non-stop. I can't dedicate an hour here and an hour there and work on it, it has to be more of a continuous process. That's why it has ta...

A little update (playable demo here: http://home.no/johan-af/chip/chip.nes ) Green buttons and toggle blocks have now been implemented. They can be seen in the fourth and fifth levels. To do this, I decided to make my game use CHR-RAM instead of CHR-ROM. This was really the only way the game could s...

I have a bit of a hard time getting an overview of your code. Could you post it in its entirety? The subroutine should not be called during vblank time, at least not before all PPU updates are done. You'll want the subroutine to store sprite data in a page of RAM, and let the contents of this page b...

Thanks for the comments. :) It's been brought to my attention that the compiled version that I have uploaded is a test version of something I tried to do a while ago. It starts of at the wrong level and the game just freezes once you've completed it. This was not what I intended to upload! I have up...

Hi again. I've uploaded a new ROM, showing what I've worked on the last couple of days. The demo shows 6 levels from the original game. My development strategy now is working on successive levels from the game, and implementing the necessary features as I go. Here's what and what's not working as we...
