PPSSPP Feature Request Page

[LunaMoo]

^Currently PPSSPP has new MT available only for Vulkan backend which might eventually be backported to OGL backend(no ETA aka it will happen when/if it will happen).
Old MT(experimental) as well as disabling alpha test were causing a lot of problems, those options were intentionally removed and will never return.

If you feel like newer ppsspp versions run worse on your outdated device, you're free to use older ppsspp versions, nobody will ever force you to update and it's actually common practice in emulation for old/hackish emulator versions to be used by people who can't afford to upgrade their ancient devices. Supporting outdated hardware can't be dragged infinitely since it negatively affects future developement especially on platforms like android where average lifespan of a device doesn't go above 2 years and things change from year to year quite significantly.

You should forget about reporting issues while using outdated versions through, time moves only in one direction(at least in practical way following human perception;p) and no changes will ever affect existing builds, bugs those versions have will forever be there.
