I don't have alot of experience, but, MMC3 seems like a clear winner as far as feature set and compatibility.

I assume most every clone console and hacked together emulator can run Super Mario Bros 3 without many issues.

You've been busy! Ill answer quickly and go into more detail in later posts if necessary. You want to take your existing sprite and store a different tile. That is the second entry of each sprite. It would be (roughly) something like this: https://i.imgur.com/nQfMzF8.png For homework, you need to ma...

I updated Snowbro's old SNDTEST rom, added some features, and made it work properly on console.

It is useful for quickly designing Sound FX / Instruments. Enjoy!

Hey stranger. The length counter (cutoff for sound timing) is bits 3-7 of the fourth register of each non-DPCM channel, so, $4003 %LLLLLxxx, for example. As long as bit 5 of the first register (for square and noise), say $4000, is %xx0xxxxx, the length counter will halt your sound after a specified ...

That camera movement is gorgeous

Any more advice I can steal from ya?

Nah man, fresh out. Step through debug your logic until it works. Keep at it!

I'm not seeing any sprites besides the ball with that build...

Yeah. Zip and link your source code folder! =p

Are you using a step through debugger?

How do you "unload a background"? Oh, i phrased that poorly, i meant storing blank tiles in the nametable(s) where the old tiles were so they aren't still on the screen when you load your new tiles. That depends on how you design your code, though; if you update the entirety of one or both nametabl...

Any tips on next step? Well, however you decide to do it, you're going to need to make a system to handle different screens and game states. If it were me, my next step would be making JSRs to load the title screen background, the gameplay background, the game over screen background, and unload the...

I think you got a handle on it mostly. The "optimized" read code looks good, i would use that. You can keep it in NMI, for now, as you probably want to check the buttons every frame, but a good rule of thumb is to process drawing / graphics first, as they should be updated in vBlank when not changin...

Ok man. More or less, you can't just "merge" these two files together and have them work. It seems like you're basically trying to run both of them at the same time. You're gonna need more code to determine what screen you are on and which inputs to process to do what. Multiple screens require a str...

Hey man! Congrats on starting your journey. I took a look and didn't fix everything, but you were RTS'ing into the great beyond on line 216 from xxx:, so the JMP xxx on line 1238 should be a JSR xxx. Otherwise, it looks like you're trying to load your entire title screen on every frame after that in...

I've been trying to get SCad to work, not much success so far... it's entirely in Japanese and is clearly missing some SDK, and probably other requirements; it also seems to need specific tweaks in the options, none of which i can read. I'd love to use it though... Files seems to be split in PRG and...

Dragon Warrior uses the BRK command to call an IRQ to run subroutines on different banks and has 1 or 2 data bytes after the BRK to indicate which subroutine and memory bank to use ... It was very time consuming to manually review all the code and find these sections. Ahhh, i see now. It's probably...
