Habemus ELFs! Not the fantasy creatures. But just a set of organized bit and bytes.
I managed to make my #kernel #dreamos64 launch its first ELF executable, although is just printing a message.
ELF support is still very limited, but, is still a great achievement for my toy project.

After more than two months another Dreamos64 update. Not new features but fixes and improvements, full story on #ko-fi
https://ko-fi.com/post/Dreamos64-Status-update-U6U71340LC (free).
I found a nasty bug in a core memory function, where i was returning true instead of false and viceversa. Also some code refactor and documentation improvements.

Habemus #scrolling (nearly) :)

I'm working on adding framebuffer scrolling in #Dreamos64
Initially it will be just scrolling the text up, when it reach the last line.
