Dreamcast:Atomiswave Games
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.

Playing Conversions on Dreamcast
Thanks to megavolt85 (and later yzb), all dumped Atomiswave games are playable on stock Dreamcast hardware. The optimal versions of these conversions come in the form of TOSEC-style GDIs, but using ISO (2048 bytes/sector) format for their data tracks, rather than BIN (2352 bytes/sector). However, burnable CDIs also exist for those using optical media, albeit with notable performance/compatibility issues.
For more information, reference the below video.
GDEMU
If using Dreamcast:GDEMU to play Atomiswave conversions, ensure image_tests=0 is present in the GDEMU.ini configuration file in the root of your SD card.
MODE
Those using the MODE Optical Drive Emulator have seen success by disabling any artificial data-read limits imposed by default for purposes of compatibility (i.e., mimicking a GD-ROM drive as closely as possible). While these parameters can be changed globally via MODE's settings menu, a safer option is to add this configuration on a per-game basis for all Atomiswave conversions. To do so, create a mode.cfg file inside of the game folder itself containing the following lines:
BlockDelay=00 Flags=7
USB-GDROM
Dreamcast:USB-GDROM users report no custom configuration is required in order to successfully play Atomiswave conversions.
Optical Media
Atomiswave conversions will also work when burned to a disc, however some titles will experience slowdowns and other performance issues. In some cases, a game fails to boot successfully at all. If you don't have any other way to run backups, it's definitely worth giving a try though!
