Dreamcast/Homebrew

The indie & homebrew game list
As hackers figured how to boot the Dreamcast from regular CDs without any hardware modding, it became, by all practical means, the most open console ever. That is, until intentionally open consoles came out, such as the Linux-based Caanoo and many Android-based portables, but I digress. Retaining a devoted fanbase even after it was commercially discontinued, it was the platform of choice for many independent developers. Thus it received several original titles, as well as ports and emulators.

Pirate compilations
As many Dreamcast games were much smaller than a CD's capacity, pirates have figured out how to make multi-game compilations. Where to get them? Hint, hint: RetroZone.co, Segahub, CoolROM, DopeRoms, Rom Hustler.

Atomiswave conversions
Shortly after discontinuing the Dreamcast, Sega realized that they still had bucketloads of Dreamcast parts. Rather than throw it all away, they quickly conocted this arcade system that was basically identical to it. Years later, some haxx0rs figured out that it was dead easy to convert Atomiswave games to the Dreamcast. You can find them here.
