SpiceWare's Blog

Added ARM and Further Reading sections.

Putting the banking hotspots at the highest addresses possible makes for easier coding as programs typically grow from low addresses to high addresses. Also, because the interrupt vectors are at the highest addresses, that chunk of memory is already "used", so reserving a few more addresses for hotspots leaves the maximum number of address chunks available.

 

Hmm... using the interrupt vector addresses as hotspots could be useful as it would auto-initialize which bank the program starts in.

That makes sense.

I do like the ZP hotspots better, like Tigervision's 3F, as they don't waste any of the ROM. Additionally, each trigger of a bankswitch uses 1 byte less ROM and 1 less cycle of CPU time.

supercat's X07 bankswitch format, used for Stella's Stocking, has a slick feature that lets you do a bankswitch without wasting any cycles, but the feature only works in the last 2 banks. He needed that ability in order to bankswitch during the kernel for his music playing menu. He posted a little bit about it here.

Found a few more links for the Further Reading section.

Revised the Display Data section.

Finally had some free time last night and was able to finish the code for Part 7. I still need to add comments and write up the blog entry, so it's not ready to be posted yet - but at least some progress has been made!

Thanks for informing us about the MAM bug! I ran into this last night and would have probably spent several days debugging it had I not read about it here.
