I was thinking about something and ended up in this discussion. I hope you guys help me:
Why aren't there (please correct me if I'm wrong) no Konami 48kB or 64kB games? (I guess they went from 32kB games to 128kB and on). Is is for a technical reason?
48/64 KB ROM need the programer to handle a lot of slot swaping because the cartridge ROM overlap with the BIOS (page 0) and/or the BIOS work area in RAM (page 3).
It's not impossible but it's complex because page 0 must contain an interrupt handler (or the program must disable interrupts) and page 3 contains the call stack (which requires to write a code without call/push/pop/... or to move the call stack elsewhere)
I guess they had to put this complexity (and its small space saving) in the balance, against the solution of a more expensive but simpler MegaROM (also offering much more space). Only the guys at Konami know what made the decision in favor of MegaROM, but good for the MSX because it led to much deeper games.
48/64 KB ROM need the programer to handle a lot of slot swaping because the cartridge ROM overlap with the BIOS (page 0) and/or the BIOS work area in RAM (page 3).
Not necessarily.
You can also simply use a normal mapper for a 48K/64K rom.
