Refactored my massive CMP branch sausages using the RTS trick, really neat stuff - https://www.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 🥵 -

You know what, lying on your back crying sucks - your tears get right into your earholes.
I made significant progress on my game this week btw.
Colors are still not fully consistent with my layout because who cares, like, omfggg who cares??? C'mooon! -

Successfully ported the #C64 #KERNAL and #BASIC to my small #ASM6502 #assembler.
Was able to produce exact replicas of the original ROMs. Nice to see the own built ROMs booting 😀

PROGRAMMATION ASSEMBLEUR 6502 #001
Deuxième chapitre aujourd'hui où il va être question de code compilé et de l'importance d'en connaître le fonctionnement.
En cas de difficulté avec un exercice, n'hésitez-pas à demander un indice en cliquant sur l'icône associé en bas à droite.
A bientôt pour le prochain chapitre.

PROGRAMMATION ASSEMBLEUR 6502 #001
Ce premier chapitre est extrêmement simple. L'objectif ici est de se familiariser avec l'interface du simulateur en chargeant différentes valeurs dans les registres A,X et Y du processeur.
N'hésitez-pas à re-booster ce toot et à remonter tout problème rencontré sur ce chapitre.
A bientôt pour le prochain chapitre.

Dès demain, dans le cadre du projet #jlodb, je vais essayer de proposer ici et de façon régulière, une formation à la programmation assembleur sur processeur 6502 (5 à 10 minutes par session).
Aucun prérequis n'est demandé, si ce n'est une légère notion sur les bases. S'il le faut, je rajouterai peut-être un chapitre ou deux là-dessus.
A demain.
