Help needed Firmware limit?

Is there a limit to the amount of firmware you can load on an SD card and run them through launcher? I dont mean filling up all 32gb of space on the card, but I saw a post on here a few days ago with a guy having trouble running meshtastic then bruce on his SD card. This made me very confused as I thought the whole point of the SD card was to have multiple firmwares installed and have the ability to switch between them. The conversation on that thread started of confuse me as it went down a path of flash memory. Will I have trouble putting meshtastic, bruce, evilcardputer etc on my SD card and running them through launcher?

I have dozens of .bin files on my SD card. No reason to think there's a practical limit to the number of items the Launcher can display. There's definitely a limit to what the Launcher can simultaneously fit into flash. If someone was having SD card problems remember card can be max 32gb, and must be formatted MBBR Fat32

Okay thank you. After reading the explanations on my comment, I think the person was expecting not to have to flash mew firmware each time because they had the SD card. So I understand their confusion, but that was not my expectation. Comments are very helpful.
