Patent and trademark rights are not licensed under this 225 | Public License. 226 | 227 | 3. To the extent possible, the Licensor waives any right to 228 | collect royalties from You for the exercise of the Licensed 229 | Rights, whether directly or through a collecting society 230 | under any voluntary or waivable statutory or compulsory 231 | licensing scheme.

The disclaimer of warranties and limitation of liability provided 351 | above shall be interpreted in a manner that, to the extent 352 | possible, most closely approximates an absolute disclaimer and 353 | waiver of all liability. 354 | 355 | 356 | Section 6 -- Term and Termination. 357 | 358 | a. This Public License applies for the term of the Copyright and 359 | Similar Rights licensed here.

Where Your right to use the Licensed Material has terminated under 364 | Section 6(a), it reinstates: 365 | 366 | 1. automatically as of the date the violation is cured, provided 367 | it is cured within 30 days of Your discovery of the 368 | violation; or 369 | 370 | 2. upon express reinstatement by the Licensor. 371 | 372 | For the avoidance of doubt, this Section 6(b) does not affect any 373 | right the Licensor may have to seek remedies for Your violations 374 | of this Public License. 375 | 376 | c. For the avoidance of doubt, the Licensor may also offer the 377 | Licensed Material under separate terms or conditions or stop 378 | distributing the Licensed Material at any time; however, doing so 379 | will not terminate this Public License. 380 | 381 | d.

For the avoidance of doubt, this Public License does not, and 398 | shall not be interpreted to, reduce, limit, restrict, or impose 399 | conditions on any use of the Licensed Material that could lawfully 400 | be made without permission under this Public License. 401 | 402 | b. To the extent possible, if any provision of this Public License is 403 | deemed unenforceable, it shall be automatically reformed to the 404 | minimum extent necessary to make it enforceable.

No term or condition of this Public License will be waived and no 410 | failure to comply consented to unless expressly agreed to by the 411 | Licensor. 412 | 413 | d.

Headphone, serial and link cable adapter in one. 3 | 4 | ## Idea 5 | The idea for this multitool is to have a single adapter board which plugs into the EXT port of a WonderSwan and handle different tasks. 6 | More specifically, this board can do the following: 7 | * **Headphone adapter**: You can plug in regular headphones with a 3.5 mm connector and enjoy the enhanced 16b audio output. 8 | * **Serial adapter**: Using the RP2040 Zero-based USB dongle board, you can use it as a PC serial adapter. You connect the WS adapter to the dongle via a male-to-male 3.5 mm cable (stereo cable) and connect the dongle via USB C to a computer. Useful for, e.g., WonderGate emulation, WonderWitch or ExtFriend. 9 | * **Link cable**: Using the WSMtool link board, you can connect two WonderSwan and use a 3.5 mm audio cable (stereo) as a link cable. 10 | 11 | ## Usage 12 | For regular headphone mode place the switch into a UP position. 13 | For serial or link mode, place the switch into a DOWN position. 14 | 15 | The RP2040 dongle works with [asie's ExtFriend](https://github.com/WonderfulToolchain/ws-extfriend). 16 | It follows the same GPIO pinout, hence no changes in the code are required, it should work out of the box. 17 | **ExtFriend Note**: The digital audio signals are not carried over to the dongle board. 18 | This means the digital audio capture via ExtFriend is not possible. 19 | 20 | **NOTE: NEVER connect two WonderSwan using two main boards or two link boards.
