Shadow of the Beast is getting a faithful Neo Geo port

Developer bendk97 has released a technical teaser and development page for a new homebrew port of the 1989 Amiga classic Shadow of the Beast for SNK's Neo Geo MVS and AES hardware. The project aims to bring the complete game to the 24-bit system, and the first footage is available on the creator's official itch.io page.

This is not the first time someone has tried to put this specific game on SNK hardware. Developer Jeff Kurtz built a primitive proof-of-concept demo back in 2006. This new attempt is a completely fresh project, built as a fully fleshed-out visual conversion rather than a simple tech demo.

13 parallax layers on real hardware

When Reflections Interactive and publisher Psygnosis released Shadow of the Beast in 1989, it was an unprecedented technical showpiece for 16-bit personal computing. Programmed by Martin Edmondson and Paul Howarth, the game pushed the Commodore Amiga to its absolute limits. It featured 13 independent layers of parallax scrolling, 128 on-screen colors, and a massive physical box featuring artwork by Roger Dean. Psygnosis built a reputation on these lavish, technically demanding computer games long before Sony acquired them to make Wipeout for the PlayStation.

The game was infamous for its punishing difficulty and finicky hitboxes. Players often died within the first two minutes. Despite the brutal gameplay, the technical achievements made it a massive hit, leading to ports on the Sega Genesis, Super Nintendo, and TurboGrafx-CD. Reflections eventually moved on to 3D games, creating the blockbuster Driver series a decade later.

The Neo Geo MVS launched in 1990. It shared the Motorola 68000 CPU architecture with the Amiga, but SNK designed its custom chips specifically for massive 2D arcade sprites. Moving a game built around the Amiga's bitplane graphics over to a sprite-based arcade board requires completely rebuilding how the visuals are drawn on the screen.

According to the developer, this port replicates the original Amiga graphics color for color. It includes every original sprite, enemy, and animation frame. The audio is also intact. David Whittaker's atmospheric soundtrack and the original sound effects stream directly from the cartridge ROM through the Neo Geo's Yamaha YM2610 sound chip. The YM2610 handles FM synthesis and ADPCM samples, making it well-suited for playing back the Amiga's original sample-based tracker music.

Still in the emulation phase

The project is currently in active development and remains untested on physical cartridges. The teaser footage shows a MAME capture of the Neo Geo ROM replaying a recorded Amiga play session, rather than live gameplay running on a physical AES console.

I am curious how the final build will handle the memory constraints once it moves from an emulator to an actual SNK motherboard. The Neo Geo has become a popular destination for ambitious homebrew conversions over the last few years. Just as with Sega's Altered Beast port for the Neo Geo, independent creators are using modern tools to push the 1990 hardware in ways SNK never officially supported.

The port is an unofficial, non-commercial fan project and will be released for free. There is no target launch date yet.
