But "Omega Blast" 0.9 ROM released - https://nendo16.jimdo.com/omega-blast/
Yes, rael16x a.k.a Nendo is good and consistent.
Ixion, Solaris, a lot demos of arcade ports, and now this Omega Blast.
Hopefully we'll get to see ver 1.0 of Omega Blast soon later.
The Shifting Catacombs, Satan Ball, Cthulhu: Tentacles of Hate, The Legend of Leyria, Majikana, Catgirl Pool Party, and many others. I haven't heard any progress of these games. Not sure whether they're still being worked or already cancelled.
