Hacking Using R4 to boot slot 2 for GBA ?

[Romnerd]

Hi - I have a Supercard SD slot2 and supercard lite Micro SD for a number of DS Lites and am considering replacing them with the best slot 1 solution.
The best slot 1 solution appears to be the R4 DS and considering I already have a number of Micro Sd's its cheap too.
However my question is about running backups of GBA games.
Am I correct in thinking that the R4 has a built in passme that enables you to use the slot 2 supercard SD or supercard lite. If the supercard in slot 2 had GBA rom backups in its SD card is it the case of just simply running the rom by selecting it and pressing "A" ????
How can you manage the GBA savegames ? Do you still need to manage these with the supercard transfer program > ?

Thank you.

When the R4 boots the slot 2, it'll act just the way it did if you had just used a passcard, so you will probably need to use all the software involved with using the Supercard normally.
