Was thinking earlier about how I used to play GT2 on my Dreamcast with the Bleem! emulator disc, it basically tidied the graphics up, seemed to perform some anti-aliasing and it looked really nice, only small downside was you needed an entire memory card/PDA thing (whatever it was called) for the save, but when I tried it you could already pick these up really cheap.
Then I remembered how the PS2 can render many PS1 games in better detail with faster loading times, so was wondering how GT2 scrubs up on a PS2?
I will probably have a look myself once i've dug out my DC, but am curious if anyone else has compared these two ways of playing!
95% of the PSX library ran at 320x240 (240p, the same as that of the Sega Master System and Sega Genesis) pixels for NTSC games. This is important to note, because it helps explain the differences.
Bleemcast (and your typical PSX emulator on the PC) doubled the
rendering resolution of the game to the default Dreamcast resolution of 640x480 (480p) pixels and added full screen anti-aliasing.
The PS2 (and the PS3) doubles the resolution to the default PS2 (and PS3) resolution of 640x480 (480i) through
upscaling and adds bilinear filtering.
Basically, the two approaches are completely different.
Playing PSX games on the PS2 and PS3 look like this:
And why Bleemcast and PC emulators look like this:
And keep in mind the second picture is technically a
lower resolution than the first (first pic is a PS3 running at 1080p, second pic is
unnamed PC software running at 720p).
And considering the PS3 does PSX emulation entirely in software, I have no idea why they designed their emulator to upscale rather than simply render higher. There is no benefit to it, because the official Sony emulator isn't any better compatibility-wise than
unnamed PC software is. At the very least, they should have compromised (lock the rendering at 720p, and then upscale to higher resolutions if need be) if the PS3 could't render PSX games at 1080p without problems.
