BIOS without logo
This is a custom Vircon32 BIOS meant for developers.
It should be functionally the same as the standard BIOS, but it will play no sound or display the logo animation. Instead it will begin execution right away. That way, programmers will not have to wait for the logo every single time when doing frequent tests.
You can make the Vircon32 emulator use this BIOS file by exiting the Settings.xml file. Another option (not recommended) is to just rename the file and replace the standard BIOS.
