+# FAQs
+
+### _Why replace `boards.txt`?_
+
+Replacing `boards.txt` modifies the pid (Product ID) and vid (Vendor ID) to:
+
+* *0x1ccf* and *0x8038*
+*  *0x1ccf* and *0x1014*
+
+for [beatmania IIDX INFINITAS](https://p.eagate.573.jp/game/eac2dx/infinitas) and [SOUND VOLTEX III](https://p.eagate.573.jp/game/eacsdvx/iii) to accept in-game input natively.
+
+### _Is there a difference between other implementations?_
+
+Yes. Older implementations found on the Internet use _NRKO_ keyboard mappings on the Arduino instead. This can interfere with other applications that require keyboard input.
