The test button is marked as 'PSW1' near the USB connector. The other button is an 'enter' button. To find out which region/version your system is, take a look at the opening where you insert game carts. You will see a large chip with something like EPR-21576D. EPR probably just stands for E-PRom. 21576 is region. The 'D' is the software revision.

We have a list on the Sega-Naomi main website. Cick here--->BIOS list
