The issue has been fixed. I reinstalled FMCB and added grimdoomer's OPL v1.2.0.6-1996 Beta, and that did the trick. Still, thank you for your time, gentlemen.
I do not. As specified in the post, I am using FreeMCBoot. I tried to set OPL to autoboot using FMCB Configurator, to no avail. It always results in a black screen, as does trying to launch OPL from uLaunchELF.
Title says it all. OPL works fine when I launch it from the FMCB menu, but every time I try booting it from LaunchELF (uLaunchELF) or set it to autoboot, I get a black screen.
This happens with versions 1.1.0 as well as 1.2.0 beta; for some reason, it worked fine with 0.9.4.
Any help would be...
