Re: Drawing ahead when scrolling up

Thanks tokumaru. Yeah, I'm only scrolling vertically and using horizontal nametables. Sorry, "expanding my background beyond 2 nametables," I meant creating a level that is more than 2 screens high. I'm really making a mess of these posts, both too long and not clear. I appreciate the help.

Re: Drawing ahead when scrolling up

I updated my map so that I have fewer tiles that are all a single color. I figured this would give me a better idea of what is going on, since I'm not updating the attributes along with drawing the rows yet.

Drawing ahead when scrolling up

I'm working on drawing a row of background ahead as I scroll so that I can expand my background beyond 2 nametables worth of data. I understand that when scrolling right or down, you want to draw to the same number row in the opposite nametable. When scrolling up or left, you should draw to the next...

Re: Decompressing NES Screen Tool map

I can't figure out how to write NameTable compressed in RLE. I tried "Selection to the clipboard" and unfortunately nothing is copied to the clipboard (there is also a choice of C code + RLE, but it also doesn't work) My understanding from browsing the forums here is that to get the RLE compression...

Re: Decompressing NES Screen Tool map

Aha! Success. I jumped to the unrle subroutine too soon, and forgot to set my pointers to the background data first. Thanks for the help, lidnariq.

Decompressing NES Screen Tool map

Hi everybody. I started following the Nerdy Nights tutorial last fall. I made it through the Pong lessons and was writing my own game along with some of the sample code portions.
