Cartridge and disk emulator

Found a Git repository from Kernalcrash that has made a number of emulator cards for old computers.

He has written that it is a proof of concept. 

Instead of using a Raspberry Pico, I made some cards from his project to save money and make them fit better.

You can find his repository at this link: https://github.com/kernelcrash/.
The cards I made are for the Amstrad, the Acron Electron, the MSX/2, the Dragon32/64, and the Ti99.

All use the same approach. The approach involves using an SD card that contains both ROM and disc images. It emulates the disc drive chip so the computer thinks it is the real thing.
