Well, other than:
1) PAL vs NTSC systems. True compatibility breaker.
2) Two different versions of SID sound chips (and every SID being more or less unique)
3) Different VIC-II versions (or at least some chips where VSP (variable screen positioning, a fast method for horizontal scrolling) works and some where it doesn't)).
