Kaico PSX Mem Card Gen 2 Memory Card Compatble with PlayStation 1 & 2- Firmware Upgradeable - Unlimited Storage - Includes an 8GB MicroSD Card - High Speed Game Memory Card for PS2/PS1/PS One Console

Well I remembered I last night that I had a SD2PSX card and figured I’d try it and it works no issue. This is the specific one I have https://a.co/d/0hqoRdW9 I also have about 12 original memory cards ranging from PlayStation official to 3rd party ones and they all worked no issue when transferring all my saves to the SD2PSX. So I’m just rolling with the SD2PSX for my saves.
