H/V tile flipping has been implemented - here is a screenshot (no flipping, H-flip only, H&V-flip). Only took about 2min to do. Probably should have done it before I made the last video. Lol. ><


But then we wouldn't get to see how the PPU actually works, which I think is what that video demonstrates.

Nice to see that my old SNES stuff came to some use. The scrolltext in the VGM player uses 16x16 pixel tiles (with BG0's tile size being changed mid-screen using HDMA), but I guess you already knew that.

Also, cool project. I certainly hope that this could eventually lead to something like the AVS, even if it's someone else doing the productification.

Nope, didn't know that. Now I know what feature I'm missing for it. Thanks!

Awesome progress so far! I'm really excited to see how things go with this, especially once you've got sprites implemented.

Keep up the good work!

Here's the latest progress update. Short video - demos the addition of fine horizontal scrolling.

It is really interesting how the fine scrolling is used for wavy effects.

Here's a new timelapse video of implementing background modes 0/1.

This will probably be my last timelapse video for the VeriSNES. While they're pretty cool (at least I think anyway) they're kind of a hassle and I'd rather spend the extra time writing code than producing timelapse videos. Heh.

You've never done wavy effects on a raster based console before?

Here's another video - subscreens and brightness control:

If anyone is interested in helping me out I would love to hear any ideas on what the heck might be going on with the weird bug in LoZ @ 6:11.

I love how hung up you got on that... :lol: The problem isn't you, it's the people who (haphazardly) made the game. There is actually a blank tile and a color palette entry that mirrors color 0. In fact, there are multiple of them: (the color of the blank tiles don't necessarily have the same value, but some of them do. Also, the first palette entry of that one palette can't show anywhere, but it's not black like the rest of them.)

Oh yeah, I looked, and all the BG layers are using 8x8 tiles for the tilemap, so there's absolutely no reason for duplicated tiles. Cgram is also a complete mess.

That's interesting. So if I understand you it seems like this problem actually will be fixed after I implement the color add/sub feature.

Yup. It was pretty fun learning how big of a mess Legend of Zelda a Link to the Past was though! :lol:

Thank you very much for the insight on that Espozo! I'm also super impressed with how quickly you figured that out.
