Its not magically easier, it's easier because enough interest was there for some people to take great pains to develop and release versatile and capable homebrew SDK (with very recent breakthroughs on that front being what enables some of the ports discussed here, they definitely weren't possible some years ago). With how many PS2 dev kits were out there I imagine it's way easier for those interested to gain access to the official SDK and with how supported the system was for that SDK to also be of much higher quality than DC's was, with it being so short term on the market and common complains about the lack of tools/still in dev tools they had to use back then. Anyway, another shitty thread of nothingness...
