DIY: ROM emulator "RPROM" for A500, A600, A2000
RPROM is a ROM emulator for 16 bit Amiga computers (A500, A600, A2000) based on the RP2350B microcontroller.
The RPROM board has a 4 MB SPI flash memory. Each ROM image is 512 kB in size, and therefore the 4 MB is divided into 8 slots of 512 kB each. The first slot is dedicated to store code and configuration data for the RP2350B. The seven remaining slots are used to store ROM images.
ROM images can be written to flash memory either via USB, or directly from the Amiga using a program called RPROM. This RPROM program is also used to switch which slot is the active slot.
The repository contains the hardware, firmware and software for RPROM. (dr)
