@aftermath You're welcome 🙂
Yeah, a 1TB SD card is probably a little bit overkill ^^
One idea is you could use the SD card as an external storage to store your roms if you use a USB card reader.
Or if you want to invest in a handheld retrogaming console in the future, you can use it for Recalbox + roms (for this kind of hardware, you don't have the choice generally)
Have fun with Recalbox 🙂
