是通过调节速度来欺骗软件，具体的，我完全不懂
以下是原文
For everyone experiencing drop offs or connection issues playing MHFU or MHP3 when starting quests, here is a trick I tried which has worked for me 100% everytime.
First off I am going p2p via tunngle (hamachi was too slow). In ppsspp go to settings>graphics>alternative speed and set it to 25%. Next go to the online hall as usual and start a quest. When everyone has joined the quest and you depart, switch on the alternative speed when the loading screen appears. Once it loads in, you can switch it off. For me, clicking in my right thumbstick switches alternative speed on and off.
Essentially, I think the monster hunter games check network latency by comparing the time it takes to send and receive a packet to some internal clock and speeding up the game seems to cause the packets to be sent and received faster but the clock is still running in real time, tricking the game into thinking the connection is better than it is. I have played both games with my friend across separate countries with no issues and drop off this way. Absolute magic. It may help in other games too, but I have only tried those two so far.
Massive thanks to everyone who made this possible, it really is amazing.
首先

设置自定义速度（自定义速度不是马上生效的东西，先设置好）

右摇杆往下按，以及’这个键就是加速按钮（其实命名有问题，是速度切换按钮），按一下就会变成你设置的自定义速度，按一下又会变回来。
于是先有人接任务，大家也接任务，然后按下变速，以25%的速度出任务完成loading进图之后再按一下切换回原来的速度。
据说很好用，我没用过，这个人用的是类似hamachi的东西，也没说几个人。
群里有人在试了，貌似还不错，大家也来检验下吧！
