UltimaVM: Update 2025-11-08 – More features added to Ultima – Function pointers, Code sections and more

Began refactoring the Drop Rock code this morning - breaking the main source into separate files, renaming functions accordingly.
Two days before setting off for the #RISC_OS London show was probably not the ideal time to do that. It's taking longer than planned. 🫤

Later this week, I'll try to rewatch @bigcar2.bsky.social's follow-up video, and try to add Golf 2024 as a third version in the same script.
Note: the purpose of this exercise isn't really to 'port' the game(s) to #RISC_OS this could be done in BASIC (and more faithful to the originals)

Wow!
At first glance.... 😲😬!
I suspect it will take quite a bit of time to solve - so I'm not even going to try right now (I do need to prep for the #RISC_OS London Show this week, after all).
Bookmarked to come back to when I have more time.
Such as when I retire. 🤣
