MiSTer implements the Amiga's custom chip set (Agnus, Denise, Paula, CIA) directly in FPGA logic on the Intel Cyclone V DE10-Nano board. This is not emulation — the chips are synthesised as digital circuits, running with cycle-accurate timing on actual FPGA hardware.
The result: near-perfect Amiga compatibility, zero emulation overhead, HDMI output with scanline simulation, and USB controller support — all on commodity hardware that costs less than a mid-range GPU.
The Terasic DE10-Nano is the base board hosting the Cyclone V FPGA. Available from Terasic directly, Amazon, and Arrow Electronics. Approximately $120–150 USD.
Adds USB hub, analog audio out, user port connector, and direct board mounting. MiSTer FPGA I/O Board v6.1 or later. Available from multiple vendors including MiSTerAddons and Antoniovillena.
The 128MB SDRAM add-on board is required for the Amiga core. Standard 32MB module works for most uses. 128MB recommended for AGA and WHDLoad game libraries.
The Vampire V4 Standalone is a fully self-contained Amiga FPGA computer with no original hardware required. It implements the Apollo 68080 processor (a custom 68k-compatible super-scalar CPU) and the SAGA chipset — a superset of the original Amiga chips with enhanced graphics modes up to 1080p.
Runs Apollo OS, a Workbench-compatible OS, or standard Kickstart ROMs. Available in V4 SA and V4 SA+ models.
Vampire cards plug into real Amiga motherboards as accelerators, replacing the CPU slot with the Apollo 68080 FPGA core. Available for A500, A600, A1200, and CD32.
Dramatically increases speed (equivalent to a 200MHz 68k) and adds the SAGA chipset's enhanced graphics and audio capabilities to existing hardware.
The Replay boards are FPGA platforms from FPGAArcade that also support Amiga cores alongside arcade hardware simulation. Less mainstream than MiSTer but respected for build quality and the Amiga OCS core accuracy. The Replay 2 supports AGA. Community-driven, open-source cores.
| FACTOR | MiSTer FPGA | Vampire V4 |
|---|---|---|
| Primary purpose | Multi-system FPGA (Amiga + 100+ other platforms) | Amiga-first FPGA computer |
| Amiga compatibility | OCS/ECS/AGA — near-perfect for classic software | SAGA superset — runs classic + enhanced SAGA software |
| CPU | Original 68000 cycle timing | Apollo 68080 — faster, not 100% cycle-compatible |
| Standalone? | Yes (DE10-Nano + I/O board) | V4 SA is standalone; accelerator cards need real Amiga |
| Other platforms | C64, NES, SNES, arcade, 100+ cores | Amiga-focused only |
| Verdict | Best for classic accuracy + multi-platform use | Best for Amiga power users who want an enhanced Amiga |
