Best: grab an internal 5.5/8Mb FAST RAM expansion (they are out there, in the internet), A601 or compatible 1Mb chip RAM upgrade, a decent sized HD (I think the installed HD is 4Gb, not 4Mb), ROM 3.1 (with the companion Workbench 3.1 installed) and the WHDLoad program.
First grab the image of your actual ROM to use with WHDLoad using Grabkick (available at Aminet) and save the image to DEVS:kickstarts/ before upgrading the ROM. Also grab the 1.3 ROM from an A500 you might have.
WHDLoad games are vastly available searching the internet.
