Hi there newest member on the site and absolute newbie
Everybody talks about what they dont now and don't understand.
So i want to tell what i now and we can start from there.
first of English is not my mother language so look threw the bad language.
LOL
Ok i read some things on this and other sites and this is what i know:
( PLease correct me if you see errors already)
I Understand
Number systems and i can read decimal/ binary and hexadecimal (hex)
The nes is a 16 bit addres bus 8 digets get cut in 2 ,twice so you will get
a 4 diget hex number,hex is show with a$ so you will get something like $4017
I understand the nes system
it has a cpu (the 6502) heart of the system
apu (audio)
ppu (grapics chip)
and lockout chip
i understand the nes cart
Prg rom/chr rom or ram/it can hold wram and lockout chip
So how do the work together?
The nes cart is put into the system and put on.
The prg rom will send instructions to the cpu (6502)the cpu gives the apu instructions for sound and the ppu instructions to get images from the Chr rom.
If im correct
I also saw a drawing of the cpu from the nes system and 1 from the nes his ppu,these drawings show all the parts and the $ hex codes that correspond with them.
And i now a little bit about opcodes and stuff,thats about it
NOW.. i saw that exsample from bunnyboy with the PPUMASK $2001 that you need to ad to get a background.
But where excatley?(under JMP Forecer )and what ppumask wont work to long only 3 digits for the upcode? so LDA $2001
So can you people help me with this tutorial and what should i learn,study next,or practice?
