Automatically Hot-Swapping ROMs in Real-Time ⚡ Software Defined Retro ROM

This week I’ve added support for automatically switching ROM images in a running system to the software defined retro ROM.

I demonstrate this by switching between different character ROMs on the C64 and VIC-20, without impacting the host.

This same feature can be used to rewrite the ROM image while the software ROM keeps running and serving bytes.
