I had a drink and I dont understand this bug...

nes stuff 

@Tanuki
0x800a LDA ABS 0x2002
0x800d BPL PCREL 0xfb
is a loop - that 0xfb is a minus that does not affect the hi byte

HOWEVER

0x8941 BCC PCREL 0x8d
is supposed to branch to 88d0
NOT 89d0 which is what my code does...

@Tanuki​ I didnt want to look at other people's code but I think it might be necessary for the PPU

This code looks pretty clear and clean

The jnternet is bad 

Slowly but surely deleting accounts on the internet of services as they become horrible and dystopian. My phone is gonna have so much free space!!

nes work 

@Tanuki right now we get to:

ROM:8E3B STA $2007
ROM:8E3E DEY
ROM:8E3F BNE loc_8E3B
ROM:8E41 DEX
ROM:8E42 BNE loc_8E3B

where we are clearing the sprite data but causing successive OAMDATA writes in the PPU, which auto increments the OAMLATCH (sprite buffer address) in the PPU

This marks the data dirty and then our DrawNameTables explodes when handling it

Older Americans are always on their phones. Except their phones are 55” on the diagonal, attached to a wall in every room, and blaring their sound to annoy everyone, and also not interactive at all.

Oh good. Fox news is on in the only diner open in town...

Meeting today in 30 min to help Cooley dickinson hospital system set up sliding scale informed consent trans care clinics in western ma woooooo

okay - I feel much better about this now - I'm, ready for @Tanuki​ to solve all my PPU and speed issues for me now that I'm fairly confident in the CPU and debugger

my carry flag conditional for subtraction operations is not right... somehow....

return ((~oldSrc + 1) & 0xFF > oldDst)

NES debugger is getting useful :)

python debugger.py smb1.nes
> bp 90cc
> g

0x90cc LDX IMM 0x7
> d S L2
0x01fd: 2e 80
> bw 01fd
> g
Write at 0x1fd

0x90de DEY

>.< its bit 7 of PPU control register 1... that masks it...

The cpu cant mask it, but the ppu can... thanks internet

How come the NES PPU non maskable interrupt DOESNT run during the first two VBlank cycles of a game's start up, but DOES run later at the jmp loop?

isnt it non maskable? WHAT MASKS IT

I plan to get very drunk with a pack of my friends and roam the neighborhood yelling obnoxious songs until people give us money to go away, and if they don't pay us we'll sack their house

Very traditional <3

HAPPY YULE MOTHERSQUEAKERS!

NOTHING MATTERS DURING YULE

THIS IS THE NON-TIME OF THE NOT-YEAR

ITS NOT 2017 ANYMORE
ITS NOT 2018 YET

GET DRUNK AND DO SOMETHING DUMB!

Ahhrrgggg.....

I'm in that place where I can't stop, but I really ought to stop and sleep, but I don't know if I can sleep right now?

I should meditate...

This 1 pysdl2 trick will speed up your rendering by 20x! doctors hate her.

It'd be cool if VBlank didnt take 45 seconds because it makes each test take a long time :/

Whoa. My emulator is very very very slow. Maybe i need to be less uh accurate and more efficient hahaha
