This is a very simple question: I am not a programmer! :)
I've uploaded a new version of 4goalux.d64 featuring much cleaner transitions between game modes. By hiding the loading commands, the experience now feels a lot more seamless and professional.
Regarding a fastloader: this is a significantly more complex task. Due to the tight memory management of the current engine, implementing one would require a major overhaul to avoid conflicts. I will continue to explore simpler alternatives, but for now, I'm focusing on these low costs improvements to make the collection as polished as possible.
Thanks for the ongoing feedback and support!
