Worked on the hacks-guide/Guide_3DS repository to implement a Version Prefix Selector within the Console Version Picker, enhancing the user flow for selecting console versions. This feature introduced options for 'Ver.', 'Sys.', and 'Emu.' prefixes, allowing advanced users to bypass the standard custom firmware check when appropriate. The solution used front end development skills with HTML and JavaScript, incorporating conditional redirects to the 'checking-for-cfw' page for non-'Ver.' selections. The approach streamlined the process for supported configurations, reducing unnecessary steps for certain version types. The work focused on targeted feature delivery, with no bug fixes during the period.
