Can the sdcard be swapped for different roms?

[tillik]

Without following your instructions, I'm assuming the new SD card will be used not only to flash new firmware but also to host the ports and roms? Is it possible to simply reinsert the SD card you may have had before? If not, it might be helpful to point out to people that they are modifying their device so that it cannot be easily reversed. (And if your new portmaster SD card is smaller than the original one, you won't be able to just copy your roms back over.)

Not sure if this is helpful but Russ @ Retro Game Corp wrote up a decent guide on this for the TrimUI Brick.

It will run old games, old apps that installed on SD card.
