libretro-super VS blueMSX-libretro

For reference, I was told that the latest build of MAME can be gotten through here: https://github.com/libretro/libretro-super

Before I knew this, I informed myself on the documentation for each core: https://docs.libretro.com/library/mesen-s/ But the description is more informative for quick overview. The description is from the .info files, in example in https://github.com/libretro/libretro-super/blob/master/dist/info/mesen-s_libretro.info on the bottom line that starts with description =

Are you missing your core info files? The core info files tell Retroarch which cores support save states. You can download them from the Online Updater or download them manually and put them in the correct directory. To check which directory they go into check:

The source is available here: https://github.com/jamsilva/chimerasnes. I made a merge request to libretro-super so that the core can be automatically built (https://github.com/libretro/libretro-super/pull/1701) but it's probably not going to be available until the next release of RetroArch.

It might be somewhere here or in libretro-super.

In any case I grabbed todays 'nightly' build from here and updated the core info file from here. The nightly core runs fine on the Mini but while the options for save states do appear in Retroarch, they do not function (saving or loading a state results in an onscreen message that states are not supported).

PCSX2 can't load .cue file, it should be removed from the compatible extensions, I even proposed a fix a while ago so that core doesn't appear anymore when selecting a .cue: https://github.com/libretro/libretro-super/pull/1569

I just looked into this for you but no luck I'm afraid. I found the April 2019 fix you refer to but strangely the libretro core documentation still says that saves & states are not supported.

That said...Big fan and request vote mention for blueMSX for MSX / SVI/ ColecoVision/ and SG-1000. The standalone has been quiet, but the core and ports remain active with great compatibility, speed, and use on almost anything (recent port on Armv8).
