You could look at sprites via YY-CHR, although they will not have any color.

I think someone made something similar, except that there is a sensitive tape inside a cartridge that if the cart is opened, it would tear and the cart would no longer be genuine. I guess the same can be here, but instead of a tape it should be some cable that will make it impossible to play the gam...

The ideal way is to use a mapper that bankswitches ROM in small chunks (1KB or 2KB), like the MMC3, because it takes nearly no processing time to load the new graphics and not many static tiles have to be repeated. So this could most likely be the way how in SMB3 the question marks were moving insi...

Sorry for hijacking this thread, but: So "sprites," as in other video game programming, are basically graphics (in this case 8x8 or 8x16 tiles) that animate , move, or may require some collision detection. And background tiles would basically be everything else. Am I correct in my understanding of t...

Ha, I never thought actually putting all these jsr s in the loop. I guess that makes sense, but I thought NES logic was different. Thanks for clarifying that. And actually, I didn't directly copy-pasted the code as I previously thought up of other methods that didn't work, but then again, the jsr s ...

Okay, so I did the following and it doesn't work: I placed this code after the second wait for VBLANK and before all of the jsr instructions: Frames=0 SecondsOnes=0 SecondsTens=0 MinutesOnes=0 MinutesTens=0 NUMBERS_BASE=48 TIME_SEPARATOR=58 NUMBERS_BASE and TIME_SEPARATOR relate to 0 and : because I...

Alright, another question: say I want to place a timer that's constantly ticking. I can't simply put it in an infinite loop that will write the tiles to the same spot, right? E.g: tick: lda $2002 lda #$20 sta $2006 lda #$5f sta $2006 lda #$40 sta $2007 rts I can't do this to place tile $40 onto spot...

I don't know, maybe I'm dumb, but I just can't get anything displayed with this code. And yes, I was switching into PAL mode just to see the top row. .byte "NES",$1a .byte $01 ;1PRG-ROM bank X 16KB/bank .byte $01 ;1CHR-ROM bank X 8KB/bank .byte $00,$00 ;No mapper DSB 8 ;Fill everything with 0s .org ...

Alright, thanks for the answers! I'll try to learn as I go along how to use scrolling and mirroring without mappers. Hopefully the whole mapper issue won't affect me at all . E: would it be possible to create a "background layer" through mirroring or is using sprites the only choice? E2: hmm, I reme...

Really, the only reason I want to use Mapper 7 is for mirroring (HUD, maybe an extra BG layer, etc.) so if there is an easy mapper (or method) to do that without all these issues and whatnot, I'd like some input.

So this is odd. I swapped to Mapper 0, progressed until it was a bit clear to me what am I doing, removed the .incbin, and found out I could only place up to 2 16kb PRG-ROM banks (.byte $02 instead of $10). That's not standard, right? How could I increase the ROM size (at the moment it's 32,784 byte...

Hi everyone! I'm fairly new to the whole NES development scene, so please bare with me. I have attempted numerous times to assemble in ASM6 (which succeeded) and run this code in Nestopia, but I get a "corrupted ROM" message. Please help me if you may. .byte "NES",$1a .byte $10 ;16PRG banks X 16KB/b...

Make up different endings based on the difficulty, e.g. the hard it goes the better the reward is.
