I've been asked to write Kazzo dumping scripts for two bootleg mappers. I think I know how the mappers themselves work, but some aspects of the script language confound me, and I've failed at finding a good source that explains what those various fields in Kazzo dumping scripts mean. This site at the bottom purports to link to a page that explains how to write mapper scripts, but the linked page only contains something about VirtuaNES that has nothing to do with Kazzo dumping scripts.

My questions are: What is a "size_base" and what value should it take, what is a "mega", what is the difference between the size_base and size_max fields in cpu_rom/ppu_rom compared to cpu_romsize/ppu_romsize? I do understand what banksize means, but wonder again why it must be specified both as part of cpu_rom/ppu_rom and as cpu_banksize/ppu_banksize, and what would happen if they differed.

mega = megabit (128KiB). Not clear why that's the convention.

size_base = the minimum size of ROM to try dumping
size_max = the maximum size of ROM to try dumping
pagesize = the number of pages

The problem I'm having right now is that Kazzo always seems to dump only the specified minimum size, instead of detecting what the actual size needs to be. If I set size_base equal to size_max however, then the actual size is detected properly. That would be all fine except that all the scripts I could find online do not seem to do it this way.
