The annoying part is that Nestopia and Nintendulator set the sprite overflow flag at very different parts of the scanline (and I wouldn't be the least bit surprised if real hardware is different still), You really need to test on the real NES as there are no emulators as accurate as those for the C...

Behold! Wow! That's amazing. If you get that thing to run on a real NES it'll be the coolest thing made for the NES to date. I find the distorted perspective cool. 3D on retro machines is usually very "vanilla", and it adds a bit of flavour. I'd love to see a version with one palette entry reserved...

... or write a tool to convert them, which probably is easier. I know nothing about this "bills world", but the data format used in SMB1 should be pretty well documented in doppelgangers disassebly.

Another guy was supposed to make some music for this, so I just whipped that one up in NT2 as a placeholder (I'm no musician (nor graphic artist) which is quite obvious). But since stuff came in the way and he didn't have time I decided to go with the placeholder. It's just a small christmas greetin...

The christmas program I posted uses a simple 8-bit linear congruential generator that looks like this: lda random_seed asl asl asl clc adc random_seed clc adc #53 sta random_seed ;random number is now in A So in math terms it's just r = (r * 9 + 53) mod 256 . It could easily be expanded to 16bits or...

haha, I never thought anyone would run it for close to an hour (even I haven't done that), so I never bothered to make it behave well when it reached the top of the screen, but ofcourse that's the first thing blargg goes to do. I hate you blargg. :) Merry christmas!

Merry Christmas!

I thought I should celebrate the fact that I'm finally able to run my code on a real NES with a small holiday intro . Uses no mapper, 16k of PRG and 8k of CHR RAM. It detects which video standard is used (I stole the code for this from Years Behind (With permission from Michel ofcourse)) and simply ...
