Also: The reason I've gone to the trouble of making a copy of my SD card and uploading it, is because the Pistorm Github is very much 'in flux'. It has changed 900 times since we got my H5 build up and running. The firmwares are all different now. They've had multitudes of tweaks for various STe platforms and as far as I know, it might not work 'out of the box' on the H5.
My SD card has a H5 setup configured perfectly, with a H5 tuned firmware all ready. It also auto-starts the emulator on boot. It also loads the Gemdos paritions and shares them over SMB... none of this is automatic. It's all manual. It also has fully configured TOS paritions and apps pre-loaded. I honestly don't think you understand how much work you're gonna have to do. (I don't want to put you off! Don't get me wrong!)
And writing an SD card image? You're on Linux man, you have access to thousands of apps that can do it for you. I simple use gnome 'Disks'. You can also get Rufus and other random things.
I basically just wanted you to get a good experience out of the box. At this rate you of course can follow the guides and do everything manually. But any issues you encounter you'll need help from
@dad664npc on Discord to guide you through troubleshooting processes - and basically I wanted to save both you and him all that hassle!

I know for a fact 1. you hate discord, so how's that gonna happen and 2. Cryptodad is inactive at the moment as far as I know.
