Okay, so I've got to the point that I have a a very early functional prototype of my game engine, with SMB3 style four-way scrolling, object collision, background collision, rudimentary player controls and some basic sprite flickering. I'm to the point now that I need to add CHR bank switching for s...

This is probably a dumb question, but Mega Man's physics work with a viewport of 240 lines, right? FCEUX by default draws 224 lines, so reverse engineering that involved the Y coordinate in combination with screenshot comparison values probably has to be redone. Shouldn't matter. The aspect ratio o...

Are you using $0200-$02XX for Sprite OAM? (I'm going to proceed in my code assessment as if you are. I think you are) If so, you wouldn't typically use that address as your actual object location. Usually, game objects are made of multiple sprites, and the draw locations for the individual sprites a...

The point I'm getting at is that game companies at the time generally did not feel that the localizations needed that much effort. I don't wanna get wrapped up in this I promise. :) (Although the audio stuff was interesting) Lots of different reasons one person could decide or be told one day to cal...

I don't think they put as much thought into localization and translating games of this era as you're giving them credit for. Even games by fantastic developers like Konami and Capcom were not except. "You now prossess Dracula's rib." "I feel asleep!!" "Congraturation this st...

For the sake of hoping they go to homebrewers, I wanted to post that EverDrives are currently available. I just picked one up to replace my much missed PowerPak, and there are now four left. I'm not sure if the EverDrives are available more frequently than the PowerPaks, but considering how many tim...

Hey I got around to playing this and it was pretty cool. Nice start! I really liked the white enemies with their mouths wide open and the boss rabbit. Cool characters. My biggest suggestion would be something with the jump mechanics. I'm not sure exactly what, because I see that the way he jumps is ...

The two background parts are two screens wide and are repeated when the level scrolls. If what you mean by this, is that two screen will simply repeat, you can do this very easily. Just draw two nametables. No complex scrolling code at all, for that part. The parallax effect will take some work, es...

Why such SNES hate? Personally, I always disliked the Genesis. The poor color rendition and the extremely limited tonal qualities to it's sound were a huge downfall to me. Don't get me wrong, I enjoyed some of the games on the system but I generally enjoyed them in spite of the system. I'm curious w...

number_of_different_metatiles * 4 bytes plus all the attribute values. Your color values will generally be tied to the metatile. At least this is how I did it. You only need two bits for color, but those have to go somewhere, so it's a good idea to share that byte with collision data. attributeAddr...

Actually, if you're using vertical mirroring I don't think you'd need to do anything near as complicated as I described. You should be able to draw full attributes off-screen in intervals of 32 pixel scrolls. Then I'd imagine you'd just ORA the four color bytes from your different metatiles. It's st...

I don't know if what I did was "good" so I hope someone will correct if I give bad advice, but what I did was something like this: (my metatile engine draws in vertical columns as they come on the screen) Set a variable as 11001100 or 00110011 depending on whether the attribute is on a mul...

I think that I will not save the individual tiles, but abstract values that stand for a 16 x 16 element. This way, I can save 3/4 of the space. How do I do this best? Do I declare a two-dimensional array where the Y dimension is the abstract value and the X dimension has four entries for each actua...

Have we finally decided that it's much easier to just load and store than to pull and push and do a bunch of other nonsense? To my n00bish understanding I believe it's situational. There are benefits to using the stack and downsides. There are times when the stack is the best option for doing somet...

And yes, I think I can manage with the restriction of the NES, however I would need a little help here and there, the wiki wasn't too informative about this part. (Or maybe it's more simple than I think.) If you stuck to the palette and three colors, I'd imagine the developer would be the one trans...
