I made some comments in a post here regarding FPGA selection for Replay2 https://www.fpgaarcade.com/replay2-the-saga-continues/ One of the reasons we have been targeting the Arduino Vidor board is to get a low-cost alternative for Replay1 for people to play with -...
Here "Erique" the world renowned Amiga demo coder is doing some actual hardware debug. I think he got a bit over excited if I'm honest.... The Vidor currently has some limitations with it's USB OTG support, primarily connecting a hub doesn't work. This is rather...
I've released a new version of the Amiga core (svn.fpgaarcade.com). New features : 48M XRAM mapped as Chip and all chipset DMA pointers support 64M addressing (optionally enabled in OSD / .ini file) CPU cache stable - 2 way I + D with full snoop. ~16000 AIBB...
The Replay Board
The Replay board is a high quality base platform for the development and usage of “cores”.
A core can be thought of as a hardware model that closely recreates the hardware of a specific home computer (Amiga, C64…) or arcade machine (Pac-Man, Phoenix…) and runs on the on-board Xilinx FPGA.
Beyond the hardware, the Replay also includes a comprehensive framework library and firmware to aid developers with core implementation and reduces the maintenance burden of supporting future replay hardware versions.
The Replay also provides ample opportunity to expand the hardware with various daughter boards for specific applications such as the 68060 Daughter Board currently in testing.
The Daughter Board
The 68K Daughter board provides a socket for an optional 68060 CPU and 128MB local/fastram for use by the 68060.
A floppy drive can also be attached to the daughter board (for use with supporting cores), making this an ideal upgrade for Amiga / AtariST enthusiasts.
In addition, the board expands the Replay’s I/O capabilities with a second SD card slot (dedicated to the FPGA), *Ethernet and *USB ports, a real time clock, *audio in socket (24-bit 96KHz stereo ADC) and Midi I/O interface.
* Audio In Record & Sampling will be driver and core dependent.
* Ethernet consists of a 100Mbit controller.
* Dual-port USB 2.0/Hi-Speed host controller.
Here’s a list of recommended parts and where to get them. Unfortunately the Replay board is out of stock and discontinued, but fear not, the Replay 2 board is in the making and will hopefully be ready soon(tm). (This version will also include USB Ports for HID Keyboards & Mice).

Cores for your FPGA Replay
Although this project started out for recreating arcade games, I wondered back in 2003 if it was possible to implement a complete home computer system. The available FPGAs were much smaller in those days, but a complete VIC20 still fit.
Now we have a large number of platforms ported, including 16bit systems such as the Amiga and Atari ST.
The focus is always on implementing the original hardware as accurately as possible, but optional improvements are available too, such as a higher speed CPU, and in the Amiga case more Chip ram, RTG graphics, and modern sound with AHI support.
