I think they must be more beautiful...
Please tell me, what should I do? Need some more softwares or hardware?
My system is Windows XP Professional version2002 servicepack3,
Intel Pentium M processor 1.73GHz
798Mhz, 1.50GB RAM

I can play Knytt Stories, with no trouble(And it's so nice).

Perhaps you downloaded a corrupted file. Have you tried redownloading it? If you downloaded the portable did you remember to extract it? Other than that it may be that you don't have a good enough graphics card.

I tried redownload, both versions(zip, installer). But result was same...
So my graphic card must be not enough.

Thanks a lot for your reply!

The links don't work for me.
TheRealTJ, it's absolutely improbable his download was corrupted. It wouldn't make much sense as he can run the game etc.

I suppose your screenshots show missing sprites.
If so, yes, your graphics card has too little VRAM.
I actually played (and beat) Saira successfully on a Geforce FX 5500 with 128 MB RAM. It worked fine. Your card must be either on-board, or just very old.
It's pretty bad anyway.
