I guess I missed the part on SMS R-Type, I thought the port was very good considering the hardware. The PCE port is much closer to the arcade but still has sprite dropouts and flicker at busy moments. The real disappointment is the SNES port, graphics look good but there's slowdown in every stage.
Sapphire would be a masterpiece on any 16-bit platform, goes to show that by the mid '90s developers knew how to get the most out of the hardware. The fact that it can load tons of pre-rendered animation from a CD to 2.25 MB of RAM certainly doesn't hurt.
