This info is in jurassic change log (eldir\docs\el-history_jurassic.html folder)... latest EL builds.
Those systems were removed in EL v6.0
Last version you can use is EL v5.9
But know that you can use AGEMAME and PinMAME with latest EL v8.2.9.
You can select a AGEMAME binary in the MAME slot, and select PinMAME binary in the HBMAME slot... if you do this, make sure to use latest versions of those two emulators.
Emu Loader supports old MAME builds all the way back to v0.56.
Remember, you cannot set emulator settings or create game custom settings with latest EL builds. You have to do it manually.
I think MAME v0.140 is the version to use with EL v5.9 (EL v6.0 adds support for MAME V0.141).
Unfortunately I don't have the binary package for EL v5.9 anymore, only the source code... and I don't have the old Delphi components to compile it.
The oldest build I have is v6.3.
You can try googling for this build or ask this in EmuChat forum.
