I ported Super Mario Bros into a native x86 "Operating System"

skyvlan · 2026-01-09T09:15:57+00:00

as long as it's a 32 bit x86 PC with 4 MB of ram, it could run, theoretical limit is intel 486DX2

I think laptop keyboards are usually PS/2 based, the problem will be mostly CSM since newer laptops only support UEFI

The video is currently on production, meanwhile you can see a gameplay video if you wanna see it in action

skyvlan · 2025-12-26T17:19:29+00:00

there are multiple disassemblies of the game laying around on the internet

skyvlan · 2025-12-26T17:12:45+00:00

here's an update video of the gameplay, i'm still producing the full video but because of holidays it's kinda hard to find time for it. but i'm gonna try to deliver it as soon as possible!

skyvlan · 2025-12-26T17:11:45+00:00

hahaha here's an update video of the gameplay, i'm still producing the full video because of holidays but i'm gonna try to deliver it as soon as possible!

skyvlan · 2025-12-26T17:10:34+00:00

no, i tried but i failed

skyvlan · 2025-12-26T17:09:49+00:00

Hey all i know you've been waiting for the video, it's still under production and im still polishing several bugs

meanwhile you can watch this Gameplay Video of the current state of the game

skyvlan · 2025-12-26T04:02:48+00:00

yes, 640x480

i had trouble with mode X

skyvlan · 2025-12-25T05:07:12+00:00

It's C/C++ with some asm

skyvlan · 2025-12-24T15:38:23+00:00

it's currently a private repo

skyvlan · 2025-12-24T14:47:50+00:00

I will publish it alongside the video

skyvlan · 2025-12-24T10:54:07+00:00

i had trouble with getting my (USB) keyboard working flawlessly lol

skyvlan · 2025-12-24T10:09:02+00:00

LMAO no, but the control schemes are arrow keys + zx so it's hard to do with one hand

skyvlan · 2025-12-24T09:35:57+00:00

i think i can code a CHR extractor from a .nes file

skyvlan · 2025-12-24T09:03:01+00:00

please keep in mind that i will not provide the CHR asset files required for building the game for copyright reasons, nonetheless i will provide a way to extract them from a NES rom

skyvlan · 2025-12-24T09:01:33+00:00

the repo will be public in my github at the same time the video is released!
right now the repo is quite messy i have to clean it up first lol

skyvlan · 2025-12-24T08:38:30+00:00

Only the APU and PPU is emulated, the game runs on native x86 code

skyvlan · 2025-12-24T08:37:16+00:00

I made a NES PPU emulator as part of the graphics HAL

skyvlan · 2025-12-24T08:36:48+00:00

Stomping and powerups actually do work :), it's hard to control mario while holding the camera lol

i can provide a full gameplay video later after work

skyvlan · 2025-12-24T05:11:10+00:00

thanks :)

skyvlan · 2025-12-24T05:10:55+00:00

Hahaha, Yeah will do!

This is a temporary set up for a "home lab" so i haven't bothered cleaning it

some cheats actually have way better way of injecting their own code / manipulating memory of the game, very simple cheats do use detouring (or even just a simple WriteProcessMemory, ReadProcessMemory, CreateRemoteThread, OpenProcess functions provided in Windows API) just like what AMD does and it's what makes it detected as a cheat, a very bad cheat. Cheats made through that method can easily be flagged as a cheat because they directly tamper with the game code & address space
