It's not really anything special, content wise. It's a nice little project but all that's new is the Redbook audio. There's tons of videos you can find. Zero new graphics. I think Bonknuts is just too busy to finish it.
If you want it so badly, go visit 4chan's /vr/ board and maybe if you beg enough, someone might send you a file link.
The Genesis remake of MegaMan (better graphics!!) and the PS1/PS2 version (same graphics but CD audio) may be worth looking into for better or similar experiences.
Also literally none of these developers give a rat's ass about their games being sold illegally, half of them are basically dead anyway. Konami is quite a greedy company and yet they've never given a Cease & Desist for the bootleg Rondo copies, despite all the angry fanboys emailing Konami.
