Redream v1.5.0 Released

Redream v1.5.0

Redream is a closed-source Sega Dreamcast emulator. It was formerly licensed under GPLv3.

2 days ago, version v1.5.0 of Redream was released, as you know, there are currently two editions of the Redream emulator, a Lite and a Premium. The Lite version can be downloaded for free, even if you still have to register on the website.

The Premium version instead can be purchased for $ 5, compared to the Lite version which supports high definition rendering. The emulator can also be run without BIOS, however using a BIOS is highly recommended as some games may have bugs, as the replacement BIOS is not currently perfect.

For those who do not know Redream, it is probably the best Dreamcast emulator ever designed that allows you to play your games in high definition.

Performance has increased dramatically, and new features such as backup states and cheat code support have been introduced to make emulation more fun. Obviously, games should run at full speed on these low-power devices. Accuracy has also been improved, without degrading performance. A February 2020 report was prepared here.
