HLE BIOS

HLE BIOS is enabled by default for Dreamcast games. BIOS for Dreamcast games is optional. However, some games may not perform as expected with the HLE BIOS or you may need additional features provided by console dumped BIOS.

In order to use console dumped BIOS, you may place the files required into the Emulation/bios/flycast/bios folder. You will also need to disable HLE BIOS in the Flycast GUI.
