emulators_libretro-kronos.shar

Last month I ported libretro-kronos to FreeBSD, which although on the surface appears to be yet another Sega Saturn emulator, it has some value since it also emulates the elusive Sega Titan Video platform.

I tried Cotton II and Cotton Boomerang, which run slowly, but as far as I can tell, rather accurately.  This port is capable of running both the Saturn and ST-V versions of the games.

It is worth noting that anther productive port maintainer also ported Mednafen's Beetle Saturn libretro core, which is the fastest and most accurate Sega Saturn emulator in my experience, although it is Sega Saturn only:

(The only other emulator to cover the ST-V platform is the current core of libretro-mame, which I have also ported to FreeBSD, and is coming shortly.  There are tradeoffs in that emulator as well, which predominantly has value in that it supports the full compatibility of current MAME versions to retroarch, but this port is the best ST-V emulator when other factors are considered).

As another basis for comparison, here is my new port of emulators/libretro-mame, which IIRC also emulates ST-V, although not nearly as well:

Doesn't build in 13.0-R poudriere: https://gist.github.com/d43481557a6dec7b45856491894bc480

emulators_libretro-kronos.diff

Thanks for letting me know, I must have built this on a system with lots of libraries installed.  I added USES qt:5, sdl (sdl2), among other revisions, so it should build with this patch

I still got error in the configuration phase about some dependency missing. I tried to fix it. Please check this patch. Thanks.

(In reply to Li-Wen Hsu from comment #4)
I will try it in some VMs that I didn't have when I first wrote this patch.

Sorry about the repeated problem in this cycle of submissions where I missed dependencies, I'll try to test my submissions on an empty jail or VM going forward to save everyone time.

Confirmed working on an empty bhyve VM running FreeBSD 13.0-RELEASE, looks like your last patch fixed the USE_QT flags fixed the qt5 problem

[PATCH] emulators_libretro-kronos.diff (tested with poudriere)

Updated patch to latest tested version, which builds on poudriere and addresses any remaining issues, if applicable.
Comment 8 Timothy Beyer 2022-05-17 04:41:20 UTC 
Note that the patch I just submitted obsoletes all other patches still present that I cannot mark as obsolete, and is standalone.

I hope that someone can commit it soon.

fix subject in patch, but otherwise identical

Note that I cannot mark other patches as obsolete, but only this patch is needed.
