Hello to everyone, I'm working a new project and this time I need more memory to store my sprites. I've always used NROM for my test, but now I think I will switch on an MMC3. My question is: Can I load sprites from a specific CHR bank and other sprites from another? For example, can I put all anima...

Wow! Looks amazing! Thanks you!

My question is, why you should make a NES without coding? To me the only reason to make games for NES is to understand how to program for old console with limited hardware, it's all about challenge. NES Maker take off all of this, so why should I make games for NES with a tool? Why don't use Unity o...

Oh thanks, I will try!

Hello to everyone, I've a "matrix" space where i translate the player by 16 pixel at time on X and Y, as you can see in the image attached. Now I need to translate an object ( sprite, pickable object, enemy etc etc ) by N cells. The first thing that I do is to put the object on the cell 0, 0 and so ...

There are other ways, but here's one of the simpler ways to select from a list of addresses (allows up to 128 of them): address_table: .dw level_0_room_0 .dw level_0_room_1 lda #1 ; change this to load other rooms asl tax lda address_table,x sta MATRIX_LVL_ROOM_ADDR + 0 lda address_table+1,x sta MA...

Ok thanks! I will try as soon as I can!

Hello! I'm working on a "level switch room", I just load my background in this way: level_0_room_0: .db $30,$31,$30,$31,$30,$31,$30,$31,$30,$31,$30,$31,$30,$31,$30,$31 ...... .db $40,$41,$40,$41,$40,$41,$40,$41,$40,$41,$40,$41,$40,$41,$40,$41 level_0_room_1: .db $D0,$D1,$D0,$D1,$D0,$D1,$D0,$00,$01,$...

I'm working a Roguelike on NES but create a randomized tiles is too slow, so I created some pre setted rooms and a random path from a room to another.

This is the first "transiction" test from a room to another . Thanks for all tips!

Thanks. Another solution could be to create a "fade in" effect that draw one column at time every t interval.

But, my question is, how Zelda room transition works? It scroll the entire screen without problem.

Hello again, I'm using your tips to implement creation of the matrix, ( 16x16 tiles ), everything works great when I start the game and i generate it with this code: gen_level_0_room_0: ldy #MATRIX_ROWS gen_rows: ldx #MATRIX_COLS gen_cols: ;jsr generate_random_tile lda #$D0 sta PPUDATA dex bne gen_c...

This code will run only once at change of the room. So it's not so critical. But thanks, I will try to study your code anyway.

This should do the trick (untested code!!) PPUSTATUS = $2002 PPUADDR = $2006 PPUDATA = $2007 START_ADDR = 2103 MATRIX_ROWS = 10 ; arbritrary value MATRIX_COLS = $13 TILE = $c2 generate_random_walls: lda PPUSTATUS lda #>START_ADDR sta PPUADDR lda #<START_ADDR sta PPUADDR ldy #MATRIX_ROWS lda #TILE g...

Thanks a lot, I will try as soon as I can.
