Yoshihiro, unarguably the most controversial person in the scene, has decided to leave the PSP scene in light of the accumulation of recent and past happenings. He's so controversial, that the second his name is brought up on our boards, we have about 11 pages in under an hour relating to the topic, of which had just resulted in a closure of our discussion thread.
Yoshihiro has been credited for the PSP Version Changer (widely used before Devhook and UMD Launchers were evident). He also contributed (credited for at least) to the first flashing application for the PSP, the first button swapper, the first UMD game launcher (via Memory Stick Pro Duo), proposed the first downgrader method for 2.0+ (largely responsible for the creation of the 2.0 downgrader). Many will argue that Yoshihiro had little to do with these creations, but this can not be entirely proven. The majority of the scene has a huge dislike/hatred towards this single man, and as a result he has decided to leave.
Many of you will rejoice in this news, many of you may feel sad, many wil feel frustrated at this man, but let's try to keep such comments to ourselves. We are not here to discredit this man anymore than many have already done, this is a goodbye post to one of the scene's longest members and contributors. Before Yoshihiro leaves however, he will be releasing a new build of his PSX emulator in which he will include the source (very large argument about the source for previous version due to his bad reputation). Please keep the comments civil and just say goodbye to the scene's most controversial person!
