TBH the whole deal with card speeds isn't a big issue though... I have a bootleg Sandisk 2GB mini-sd card which infact only has a 1GB capacity and gets a 2 rating on the castlevania test (if that), on my SC Mini-SD and Castlevania aside there is no slowdown/pausing/lag in any games in either gameplay or fmv.
A-Data all the way. Kingston is great too. I got a 2GB version, that gets 5/5 on Castlevania. A friend has a 1GB kingston that is also 5/5. We had to "tweak" the card to make it work tho. Here is a quote from what I found on another board:
Another Forum said:
This will *ERASE* All data on your media card. Be sure to back up all your information first. This changed the amount of sectors on the card to allow quicker data transfer:\
Change "CARD" to the letter of the drive that the SD or CF card is inserted into:
Click on Start-> Run-> Type in cmd and press ENTER
8GB CF card:
Format CARD: /FS:FAT32 /A:64K
4GB SD or CF card:
Format CARD: /FS:FAT32 /A:32K
2GB SD or CF card:
Format CARD: /FS:FAT32 /A:16K
1GB SD or CF card:
Format CARD: /FS:FAT32 /A:8192
My 2GB MiniSD card when formated above gave me 5/5, before it was about a 4 (it stuttered only twice). My friends stuttered 4x on his 1GB Kingston. Using the above settings it's flawless.
I'd go over to www.m3wiki.com and look at the carts that are the best, then use those settings. I bought all my media from www.newegg.com no tax to my state, but shippeding was about $4-5.
