Problem loading game with slow CF card with SuperCArd

I experienced some loading problem when I played “0083 - Osu! Tatakae! Ouendan (J)” with my Super Card (with Firmware 1.52, of course). I suspect that it’s mainly because the game loaded directly from the card, and the card I used was a regular slow Transcend Compact Flash 256Mb card. I tried Kingston Elite Pro 50x Compact Flash with 2Gb this morning, and didn’t experience any problem at all. So maybe a faster CF can solve the problem.
