X-Troll Products - Danger Zone for Megadrive

Danger Zone was planned to be released for the Sega Mega Drive (aka Sega Genesys) but since I got no documentation and failed to produce sound, the project was aborted.

A playable image of the Danger Zone engine can be downloaded by clicking onto the screenshots, the Sega and X-Troll logos are not included in the demo. I have added them, to show that we leave the world of Atari here.

How to play Danger Zone with a real Mega Drive

You will need a Super Magic Drive or a similar device to play Danger Zone on the real hardware. With that device you can simply load the image from a floppy disk or transfer it via a parallel cable. However the Super Magic Drive might be rare nowadays so you might want to try an Emulator instead of a real machine.

How to play Danger Zone with an Emulator

The image works fine with Mega Drive / Genesys emulators like Gens, which I recommend since it's nearly perfect. You will have to adjust some settings in Gens to get a proper setup.

Set Country to Europe (PAL), because Danger Zone was coded for the European Mega Drive versions, otherwise the visible screen area will be too small. You have to use the Menu CPU > Country > Europe to get that done.

Enable vsync, to get a smoother display without glitches. Just make sure that the menu Graphic > VSync is checked.

Set frameskip to automatic to get the approximated speed of the real version. You simply have to select the menu Graphic > Frame Skip > Auto.

Configure your joypad or some keys if you don't have a real game controller. Controls can be configured with the menu Option > Joypads...

How was it developed

It was developed on an Atari ST which was connected to a Sega Mega Drive via a Super Magic Drive copy-station also known as SMD800. Of course I used Turbo-Ass for coding and NEOchrome for the graphics of this unfinished game. Beside that I rewrote the transfer routines from the SMDsend. This allowed me to assemble directly into the Super Magic Drive without the need to put anything to disk.
A Z80 debugger was started too, but was never finished. I intended to use it for reverse engineering the usage of the Mega Drives sound hardware.
