Build tool option InstallRAMISR is used to automatically select RAM in page 0 then copy data there at startup, so ROM cartridge can take advantage of 16 KB of additional RAM.
As page 0 (addresses 0x0000-0x3FFF) is the place where MSX will search for interruption handler (ISR), the build tool will automatically copy the selected ISR (see CustomISR option).
InstallRAMISR can take 3 values:
- RAM0_NONE: Don't install anything in RAM
- RAM0_ISR: Install only ISR
- RAM0_SEGMENT: Install ISR and segment data (for mapped-ROM)
