Okay, one more thing is bugging me as I try to crunch some numbers. A while back, I had gone frame-by-frame on some footage from some Mega Man NES games to try to reverse-engineer exactly how the player moves, so I could use that to build a game that felt more fun in its control. What I found was th...

I was looking through this thread again and it occurs to me that I never thanked tokumaru for his helpful information. Thank you for explaining how the NES handles its framerate. Especially after reading it again, I think I understand. The NES hardware, I assume, calls a frame to be drawn at an exac...

DMC = delta modulation channel Ooooohhhhhhh!! That makes sense. The DMC has a 7-bit "current value" register. Raw PCM playback feeds individual samples to this register. When I read that i thought... Could you feed the DMC the result of an algorithm to produce another simple wave, like an...

I'd change the brown color on the blocks to a dark blue, because I'm under the impression that the lighting in the room is more blue colored than it is brown because of the purple background. Hey, actually, you'd also only be using two palettes instead of three. Have you thought of adding torches o...

Marscaleb, can you clarify which you mean...PCM samples or DPCM? Okay, I was not really aware of these differences. I was reading on some other thread and the gyst I got was that "DPCM" was just being more specific. I was under the impression that the NES could not do formal PCM (as compa...

Each sample takes a bit, but the amount of ROM you want to dedicate to DPCM is up to you. Huh? Just one bit? Oh jeez, I totally forgot what "sample" refers to with PCM data. That's just any one of the dots in my wave, when I zoom in real close. I was thinking of sample as in a clip of sou...

And here's a sample tileset for a dungeon-like level. http://eightballgaming.com/img/Sample006.png I also have a couple different variations on the stairs included. Plus, I have plenty of space left over for extra tiles, so maybe I'll add in some more variants or extra detail, but honestly there isn...

I was thinking about the capabilities of the PCM channel in the NES, and I started to wonder if I could create some samples that meet the requirements/restrictions. I don't think I will truly understand what kind of sounds the PCM channel can handle until I am condensing the samples myself. So, what...

This is really coming together! I think his head should move a little. In fact his body should bounce some. It seems strange that he's running without going up and down. I could do that. http://eightballgaming.com/img/SampleRun.gif http://eightballgaming.com/img/SampleRun002.gif Also, here's an alt...

http://eightballgaming.com/img/SampleRun.gif http://eightballgaming.com/img/SampleFull.gif I decided to splurge and use six frames for the running animation. Using CHR-ROM I can easily swap out tiles for new animation frames, so I have some extra space for extra frames. I'm not very experienced wit...

But they only use two shades when everything else uses three, and there doesn't seem to be anything else tying up that extra palette entry anymore. I drew this leaving one whole palette unused (and at least 64 tiles unused) so I can add extra elements later. This is still just an early experiment, ...

I spend some down time at work restarting the second forest tileset, and decided to spend my time today finishing it up. I've also got another revision on the main character; I took the two palette trench coat version and turned it into a single palette version, and modified the design of the outfit...

It's 06 and 07.
And 05 and 06 look even more alike.

Yeah, it does look better when I use the dark/outline color from a different hue. Thanks for that pointer! I've tweaked the leg for the main character, plus the neck in Darryl's version. I also tried a different version wearing a trenchcoat that uses two palettes. And made some more monsters. http:/...

Wow, you turned the trenchcoat into a cape! It looks awesome, but I also keep thinking... I thought I was gonna slay Dracula, not become Dracula! :) (Actually not developing the story yet, but Castlevania inspired and all, so final boss is likely to either be Dracula or some original demon lord.) Yo...
