ACouple of newbie questions

[rapscallion]

I have a r4 card which is a clone. I have the games working on a 2gb micro SD card. I have copied the files to another 2gb card and put new games onto that card and they work but I cannot get a bigger sized SD card to work.
How do I found out what the software is on r4 card revolution card and also what firmware is on the D's lite. Is there firmware to get a bigger card working.-

those cards don't support sdhc cards, so you wont get anything bigger than a 2gig non sdhc card to work.
