For the most part, applications that follow Apple's programming guidelines will work on either ROM 01 or ROM 03 equally well. The main functional differences are that ROM 03 has a more flexible slot assignment scheme (of no interest to typical applications), ROM 03 has more ToolKits wired into ROM (versus loaded from the System Disk), and ROM 03 machines come with more on-board RAM (1.125MB total vs. 256KB for ROM 01). Most GS- specific applications require more than 256KB of RAM; 1.125MB is enough for most (but not all). More significant differences lie in the various releases of the System Disk (GS/OS). Version 5.0.3 is the latest release, with 5.0.4 rumored to be imminent. Newer versions offer features that older versions didn't, so if an application depends on such new features it will fail if you try to execute it using an old System Disk.
