Great work, thank you very much, Chili! All the sram issues are gone, the Save Ram manager now works flawlessly!
Found a possible bug: can't start Sega CD in BRAM mode with SCD_SRAM.bin. Tried CDx and the Sega CD II models, both didn't boot. I noted the Run Mode is: 0x1 - Type MD. Tried burning the ROM by the Myth Programmer and by Madmonkey's programmer.
