Jiffydos-c64.bin ((install)) Site

The C64’s Kernal ROM is soldered on many older boards. You may need a ROM adapter, a Kernal switcher (for dual ROMs), or strong desoldering skills.

On physical Commodore 64 hardware, this binary is burned onto an EPROM chip. This chip is then installed into the KERNAL socket on the motherboard, often using a "switcher" that allows you to toggle between the original Commodore KERNAL and JiffyDOS. jiffydos-c64.bin
