Commander X16

I am.

I'm trying to load ASMEDIT into the editor via: sarasaworks$ ./x16/x16emu -prg ASMEDIT.PRG -run But instead of running, it either loads to a discombobbled emulator screen or into the monitor with the following readout: B* PC: 9F0B RA: 03 RO: 00 AC: 01 XR: CC YR: 00 SP: 01 Flags: ..***.** The one tim...

Good call! Thanks! I edited my code accordingly

So, after a few videos and deciphering how to manipulate VERA and VRAM, this was my conclusion: stz $9f25 ; Select VRAM Data Bus Zero lda #$00 ; Low Byte, 17bit VRAM address ($1FA00) sta $9f20 lda #$fa ; Mid Byte, 17bit VRAM address sta $9f21 lda #$11 ; High Bit, 17bit VRAM address + 1 byte stride s...

I just know that defining palettes on the NES is as simple as:

P0: 
.byte $00, $03, $42, $D3

P1: 
.byte $00, $01, $02, $03

And then sending them to the proper PPU address... Was looking for something similar.

I'll look at the BASIC file in a bit. Don't have a reader on my phone.

I am playing with tiles and sprites at the moment, but where I am struggling is defining a set of palettes. I saw a small section on palettes in the VERA docs. It shows how the colors are defined, but not how to compile those colors into usable/swappable 16 color palettes that can be sent to VRAM. I...

My name is Rock, and I am happy to be able to follow such an epic project. I have been seeking a robust way to teach my daughter, Sakura how to write for the 6502 for a while. Hovering over the Apple ][ series and the NES as options for her startingpoint. Spending time in the documentation and playi...
