About the Saturn bios, I'm sorry but you've to look for them on your own as it's not allowed to ask for/post Rom links here, please use
Google, are not hard to find indeed:
Code:
Region Filename Size CRC32
------- ------------ ------ -------
Japan : SEGA_101.bin 524288 224B752C
USA : SEGA_100.bin 524288 2ABA43C2
Europe : Euro.bin 524288 4AFCF0FA
Those are the most usual names, but the size and CRC should be the shame
