[QUESTION] How to enable/disable engines? #1

Closed vanfanel closed 2 years ago

Hi @diablodiab

I am very happy that you did this, because Scummvm games benefit ENORMOUSLY from shaders and RetroArch in general!

Reading the build instructions, I couldn't find any mention to engine enabling/disabling, and looking at the build sources themselves I found that engines.mk mentions using the configure script to enable/disable engines. However, the only configure script I see is the upstream scummvm one, that doesn't seem to do anything to the libretro build files.

So, what's the intended method? Manually editing config.hd?

Thanks!

All engines can be enabled/disabled in /build/config.hd, /build/config.hdlite and /build/config.nohd. To disable some, just comment any line with #.

@DrUm78 Thanks! In the end, if manual enabling is the way to do it, I will use my own custom .config

DrUm78 commented 2 years ago

That can be set in the Makefile too with NO_HIGH_DEF, LITE or NO_WIP: https://github.com/diablodiab/libretro-scummvm-backend/blob/cb6918cf0f700d638466ff23c11ed2c057a0e1d1/build/Makefile.common#L14 But this way is less flexible if you want to enable/disable only some of them.

@DrUm78 Yep, I am passing my own config to the include in Makefile.common
