Question: Following the discovery of a buffer overflow vulnerability in the Wii version of Twilight Princess, an exploit known as the "Twilight Hack" was developed, allowing the execution of custom code from a Secure Digital (SD) card on the console. A properly designed save file would cause the game to load unsigned code, which could include Executable and Linkable Format (ELF) programs and homebrew Wii applications. Versions 3.3 and 3.4 of the Wii Menu prevented copying exploited save files onto the console until circumvention methods were discovered, and version 4.0 of the Wii Menu patched the vulnerability.
Is there an answer to this question: Which issue of the Wii Menu fixed the issue with Twilight Princess?

Answer: 4.0

Question: This technique was very expensive, though, and could not be used for applications such as telemedicine, distance education, and business meetings. Attempts at using normal telephony networks to transmit slow-scan video, such as the first systems developed by AT&T Corporation, first researched in the 1950s, failed mostly due to the poor picture quality and the lack of efficient video compression techniques. The greater 1 MHz bandwidth and 6 Mbit/s bit rate of the Picturephone in the 1970s also did not achieve commercial success, mostly due to its high cost, but also due to a lack of network effect with only a few hundred Picturephones in the world, users had extremely few contacts they could actually call to, and interoperability with other videophone systems would not exist for decades.
Is there an answer to this question: When was the first slow-scan video systems researched?

Answer: the 1950s

Question: Information of the oldest teachings may be obtained by analysis of the oldest texts. One method to obtain information on the oldest core of Buddhism is to compare the oldest extant versions of the Theravadin Pali Canon and other texts.[note 27] The reliability of these sources, and the possibility to draw out a core of oldest teachings, is a matter of dispute.[page needed][page needed][page needed][page needed] According to Vetter, inconsistencies remain, and other methods must be applied to resolve those inconsistencies.[note 28]
