Nintendo DS and R4 Revolution

[True Blue 32]

Can anybody tell me the difference between R4 Revolution for DS and the R4 HCSD Revolution in leymans terms.

My daughter had one bought for her for christmas and liking the look of the games, i decided to copy a few onto another micro SD card which i succeeded in doing with the hardware that was supplied with the card.

If i put the new Micro SC card into her R4 HCSD Revolution cartridge it works fine. If i put it into the new R4 Revolution cartridge I have, it gets stuck at loading.

Does anyone have any ideas?
I guess i must have ordered the wrong one, but it did state that it was for use with the DS lite when I bought it.

The r4 sdhc (high capacity) will support a higher memory card (4gb upwards) as opposed to the r4ds which will only take 2gb sd memory.
Please note the r4sdhc is in fact a clone and not made by the r4 team.
The firmware is different on both cards hence the reason it will not work when you place the memory card from the r4 sdhc into the r4ds.
