The MAME Reference Sets are listed below:
|MAME 0.37b5||2000||mame4all-pi, lr-mame2000|
|MAME 0.78||2003||lr-mame2003, lr-mame2003-plus|
|MAME 0.94||2005||AdvanceMAME 0.94|
|MAME 0.106||2006||AdvanceMAME 1.4, AdvanceMAME 3|
Emulators starting with lr- are libretro cores, so they enjoy all the benefits of that: centralized controller configurations, many customization options, netplay, shader/overlay support, etc.
In general these modified older versions of MAME were created for smaller systems with underpowered processors such as the Raspberry Pi.
|ROMs (non-merged) sets||can be built using the recent "MAME ROMs" and "MAME Rollback ROMs" source sets with a ROM Manager, the (non-merged) dat-file and the guide linked to the sets.|
|CHDs (merged) sets||can be built using the recent "MAME CHDs (merged)" and "MAME Rollback CHDs" source sets with a ROM Manager, the (merged) dir2dat dat-file and the dir2dat guide linked to the sets.|
N.B. using the dir2dat dat-file for CHDs ensures building the correct CHD version (v3, v4, or v5).
|Sound samples||can be built using the "MAME Reference Set Samples" set with a ROM Manager, the dat-file and the guide linked to the sets.|
The dat-files are not available to be downloaded currently.
The guide on how to create the Reference Sets is at MAME ROMs Set Creation using a dir2dat (With ClrMamePro).
It's recommended reading MAME Split Merged and Non-Merged Sets.
