 ## Version History
+20230513 - 1.8: Discovered two "unused" images (the yes/no buttons) are indeed actually used, when being asked if you want to overwrite a saved game.
+
 20230512 - 1.7: Added a note about stock battery runtime. Added a section with information about A/V output performance. Added a bit of info about PAL/NTSC region speed for Genesis/Mega Drive. Retitled the "bisrv.asd" section to make it clearer that's the BIOS/firmware. 
 
 20230511 - 1.6: Added a quick note about the display panel to the Hardware section, and added a new section for Emulators, including an incredible collection of ROM notes for Arcade thanks to `adcockm#8175`! Also added a "silent" background music file for download, and a table of contents (this page is getting fairly long 😅). Added a `favicon.ico` to get rid of that one annoying console error.
