Anyone get this working? Been trying to build from the git. Tried the main fork and the RetroPie forks, both seem to fail because of "Makefile:325: recipe for target 'obj-dreamcast-armv7h/rec-ARM/ngen_arm.build_obj' failed". Seems to be related to not being able to replace gl2platform.h and khrplatform.h and using the ones from sunxi-mali-r3p0 doesn't seem to work.
