Pas trop présent sur le Fédiverse en ce moment. J'avance toujours sur mon simulateur de processeur 6502 mais la création de niveau est extrêmement longue...

Voici 2 exemples parmi les premières missions.

Something absolutely crazy just happened! I wrote a bunch of code (by my standards, which are poor), then compiled it and executed it as I normally do, and it just worked right away.
It's this jump, blessed by Assembly God!

Refactored my massive CMP branch sausages using the RTS trick, really neat stuff - nesdev.org/wiki/RTS_Trick
Scared of indirect jumping because of the weird non-obvious bug that I stumbled upon. Something about the lower byte of an address being stored on the last memory page. So hard to keep such things in mind 🥵

Une deuxième mission en assembleur 6502. Pas très différente de la première, mais désormais l'aide (le point d'interrogation) est disponible.
