Re: A question Tables, indexing, and banks
This is very helpful thank you. Mode 21 looks interesting but more complicated than mode 20. I'll probably look into it way later on but stick with mode 20 while I am still learning the basics. Those maps from tepples are a great visual! Looks like I am good to go for now. Not to mention a lesson I ...

Re: A question Tables, indexing, and banks
Thanks! On that note I'll probably stick with what I am doing now unless I find I have a particular need to use another way. edit: Also I see it now(The 20 & 21 corresponding to LoRom & HiRom). In Neviksti's original header he has it commented: .DB $20 ; Memory Mode ( $20 = Slow LoRom, $21 =...

Re: A question Tables, indexing, and banks
Thank you both for the replies. Modifying the DBR is exactly what I was looking for. So now I have: lda #$81 pha plb ldy #$05 ldx $77 lda CollisionMap,y sta $10 Which produces the expected result when my table is stored in bank 1.

A question about Tables, indexing, and banks
Hello! I've been writing and studying basic SNES/65816 examples that I can look at in a debugger since visually analyzing things enables me to learn better. One of the more basic concepts which I thought I fully understood but apparently don't is tables. My main question is: Is it up to the programm...

Re: Questions about NMI, VBlank, DMA, & HDMA
This is excellent information thank you. I'll keep reviewing, re-reading, and checking out the links provided in the thread. That's the correct phrase.

Re: Questions about NMI, VBlank, DMA, & HDMA
First and foremost thank you to all 4 of you for your replies. Each one has helped me understand much better certain things I didn't understand before. I'll definitely have to come back and re-read them numerous times though until it's hammered into my brain. However, my initial takeaways are: - All...
