There is a Wi-Fi chip in the cart, because "why not?"

It is rollback netcode, because everything is possible!

First running concept of the online menu. Lacks tons of details, but hey! There is a big earth!

New devlog entry: rollback netcode on the NES, technical tricks to make it work

#emscripten evolves fast, breaking compat every now and then.

As I regularily compile a big project, I may reference such changes (and how to adapt your build) in a thread.

First entry, right now!

Emscripten 2.0.7: emcc no more link in C++ mode.

Symptoms: lots of c++ symbols not found at link time.

Solution: link with em++ if you have some c++ in your project.

Here is some crossplay between a NES and a PC

It is exciting to see it coming to life! If porting modern games concepts to a 8bits CPU and 2 KB of RAM is not an easy task, it is a very rewarding one!

(If you don't know it already: it is an online smash-like, for the NES)

Got interviewed for fanbyte, about what is special in developping demakes in regard to original games, and adapting modern gameplay to constraints from 1980's

🤦‍♂️ Ok, found it. Add "memory" to the clobber list to tell the compiler that the asm block may access memory.

That was clearly stated at the bottom of the documentation... Next time I should RTFM to the end. (spoiler: I will not)

Is there some #gcc guru out there? About #cpp optimization?

In the following code, gcc allows itself to prune the "*buffer = 1;" from "extend_asm()". I marked the asm block volatile, as per my understanding the compiler should be aware that this block may have side effect (like reading global data). Also, with a basic asm block it works as expected. What did I miss?

Once again, I completely failed at writing a good letter to Santa.

Should have asked for electric tools, and a workbench 🤦‍♂️

I have a new shelf!

Exactly 1x1: one macbook deep for one old plank long. Take it metric system!

Hi, I am Roger Bidon, and just migrated from a little instance to the big city!

You may remember me from photos of NES development, like the one below. I am actually making an online game for the NES, with a Wi-Fi chip in the cart.
