Looking to mod my SCPH-102 PAL Slim PSOne console, and set it up with freepsxboot/tonyhax. However I don't know how to determine the exact BIOS version that the console is? I've attached pictures of the bottom of the console, the BIOS screen, the memcard screen and the CD player screen in case it can help, and if not, if someone can let me know a way to determine it?

Thanks in advance

Boot into Unirom. It can determine the BIOS version (or at least some kind of checksum which can be compared to known values).

But for the decision which file to use for flashing a FreePSXBoot Memory Card there is no reason to know if v4.4 or v4.5. A lot of differently named files have been prepared for FreePSXBoot – for the case that additional differences show up when adding features (if I remember that correctly). In practice not all files are unique. Your case, v4.4 and v4.5 is exactly such an example. Please have a look at the md5sums:
