Dreamcast Atomiswave Ports

Here’s a list of all the Atomiswave games that have been ported to the Dreamcast:

Performance Updates:

If you’re running these games through a GDEmu, you might need to set “image_tests=0” in the gdemu.ini.

People using the MODE Optical Drive Emulator have the ability to overclock the MODE to reduce slowdown. To test this, just create a “Mode.cfg” file inside of the game folder itself containing the following lines:

BlockDelay=00
Flags=7

These ports will work when burned to a disc, however you might run into some slowdown or loading issues. If you don’t have any other way to run backups, it’s definitely worth giving a try though!

What is Atomiswave?:

The Atomiswave arcade platform is seen by many as a spiritual successor to the Neo Geo MVS, being a collaboration between Sammy, SNK, and Sega. Interestingly, it was very similar to the Dreamcast hardware, even more so than the Sega Naomi. Unlike Naomi though, Atomiswave has been largely overlooked due to its rarity and relative failure to successfully break into arcades. The Dreamcast Junkyard has a great piece on the history of the Atomiswave with more technical details that I encourage you to check out.

How can Atomiswave games run on the Dreamcast?:

Unlike the Sega Naomi arcade platform, the Atomiswave uses pretty much the same hardware. While the GDROM and discs are replaced with cartridges, the main processors and RAM are the same. The main difference between the Dreamcast and Atomiswave are how it processes it’s I/O and that’s what these conversions are centered around. For more info, please check out the video below:
