it has been noted by AJR that the main ROM is a bad dump at the moment, so setting this to draft until it's redumped

The cartridge, by the way, is titled "Shoujo Manga Collection" (少女マンガコレクション), and its nominal media type is "Illust-Cassette" (イラストカセット). Unlike the main ROM, it doesn't seem to contain any V25 code.

As for the mapping of the main ROM, I suspect that all the program code is contained within the second 512K bytes of the main ROM, which should be permanently mapped at 0x80000 to 0xfffff, with the rest being bank-switched somewhere else. Unfortunately the second half of that 512K is presently missing.
