save size is automatic but not the save type. if a card uses a proprietary save the ak firmware can not decrypt or convert it on the fly. setting a save size may cause the rom to fail and in some cases (like kage2) you have to manually set it for it to work on the rpg. your r4 saves will work to a certain extent. the r4 and ak use the same save type. however, if you drop a save on your rpg it may be overwritten. on boot up. the lastsave.ini will overwrite your last played game's save file with whats in sram. try the following…
based on akaio:
run a different rom and play for a second
turn off the nds then turn it back on, the last save is now dumped
turn off the nds, take out your rpg, and put on the new save file for the different game
boot it all back up and give it a try.
i'm still trying to wrap my head around savelistex.bin on the rpg. it seems that it associates games with save files. on first run of a rom a save is made and the associated information is stored in the savelistex.bin. if you add a new save for a preassociated game the save will just be overwritten with the old associated values. when you swap firmware, save this file as it will allow your old games that already have saves to work. (i think ;P)
i haven’t used gelu’s firmware on my rpg so i can’t comment on it.
that has worked for me, i hope it helps you.
