MiSTer FPGA Forum

I have added some improvements to the BIOS menu:

• BIOS writable option
• Fix overlap in OSD menu between ROMs (Fx) and images (Sx) save in config

The solution to the overlap requires an update of the Main, I have already opened a pull request, it is waiting for sorgelig to accept it and finally publish it for everyone:

https://github.com/MiSTer-devel/Main_MiSTer/pull/694

In the meantime, I attach it here so that you can try it out.

Regarding the writable BIOS, the options are:

• None (default)
• EC00
• PCXT/Tandy
• All

This functionality is primarily intended for developers, so that BIOS debugging is possible. However, when XTIDE is not required in EC00 (BIOS that allow F000 hosting), 16Kb of additional UMB memory space can be gained.

And of course, in any case, the associated files on the SD card will not be affected. The content of this memory will be restored when the core is rebooted.

I will soon release these improvements for everyone, but you can try it out.

Enjoy them!
