Backward Com patibility

Com patibility with older software can be done in two ways: Hardware and Software.

Hardware:
a) Install a Kickstart ROM Switcher to allow you to switch between Kickstart 1.3 and later Kickstart

Software:
a) Use a SoftKicker program  to load old Kickstart into m em ory e.g Skick

b) Use Disk to Hard disk program s such as JST and W HDLoad to copy the gam es to hard disk and
em ulate the older system .

c) Use the CPU com m and to turn off features such as Caches on processors such as the 68020 or
later.

d) Use the Kickstart Startup screen (press both m ouse buttons at startup) to select which Chipset to
use.
