It's no secret that NIS used AI (for image upscaling) in the PC ports of their older titles like Rhapsody 1, 2, and 3, and La Pucelle. I know this because I've played them (the PC version on Steam) and I did notice the AI-upscaled images.
Disgaea 3 and D2 suffered from the difficulty of being ported to PC because the console they were made for (PS3) had a very unusual architecture (Cell Processor).
Now, with AI, it's possible to reverse-engineer several games and port them to different platforms.
I'M NOT ASKING ANYONE OUTSIDE OF NIS TO PORT DISGAEA 3 AND D2.
I want NIS to take advantage of this opportunity and port those PS3 games that their community has been asking for.
PS: I hope they don't do heavy Vibe-coding and end up with an inefficient port full of glitches.
