@mz: I just looked at a YouTube video, and it looks like there's a really obnoxiously long load time every single time one of your units clashes with an enemy in the PSX version. Considering I could just play the SNES version with no load times, I would find this unbearable. If you use Google, you can find other people complaining about the load times, so clearly I'm not the only one bothered by it.
I think you're kind of exaggerating how much better the PSX version looks. Overall, it probably looks better, but honestly not by that much—and I actually dislike the PSX version's font. Even if the graphics look a little better, they don't make up for the load times, especially if someone did an enhanced music hack for the SNES version. Obviously it's totally fine if you prefer the PSX version, but it's not for me.
