King's Quest V Persistent Battery Saves

Hack of King's Quest V: Absence Makes the Heart Go Yonder


King’s Quest V was an interesting beast. There was SRAM on the cartridge, but no battery. The developers included a save feature, but without a battery, it didn’t persist across hard resets. Furthermore, they added code that clears out the SRAM upon a cold reboot (presumably to prevent partially-corrupt saves from being loaded after rapid power cycling). For this hack, a few instructions have been changed to prevent the pertinent areas of the SRAM from being cleared upon a cold reboot, which allows emulators, flash carts, or reproduction cartridges to have a fully-functional battery backed save.
