Скачать или смотреть IRQHack64 Cartridge + JiffyDOS image + SD2IEC

The IRQHack64 cartridge autoboots a slightly modified version of JiffyDOS image into the RAM and runs it there.

The main purpose is to imitate JiffyDOS kernal via the IRQHack64 cartridge. This cartridge loads/autoboots programs from a SDcard. This way, a C64 can be booted up with JiffyDOS without any hardware modification.

Just save this jiffyram.prg file ( http://cbm.ficicilar.name.tr/program/... ) in a SDcard. Then power up your C64 with this SDcard and IRQhack64 cartridge. Select the jiffyram.prg from the menu. Later, press its button for 4 seconds to mark it as autobootable.

Of course, it can be loaded and run standalone as well.
