Title: Romset Rollback
Post by: Fighting Fish on March 20, 2008, 07:15:31 pm

Greetings,

I have the rom set .120 and am pretty happy with it.  However, I am creating a couple bartops on older computers.  500-700mhz range.  I would like to use the .60 version of Mame.  So I am wondering where I could find a rollback dat for use in clrmamepro?

I'm am willing to rollback the roms and use the version of mame from anywhere from .55-.60.  I've heard these versions like my speed of processors.

Clrmamepro should use mame to generate the dat file.  Just set cmpro to point at the 0.60 mame like normal, but change the emulator to "old_mame" instead of mame.

Do you have a roll back set of roms?

I guess I am not sure what a roll back set of roms is?  I assumed it was the product of rebuilding my .120 romset to work in Mame .60.

A rollback set of roms has any files that have been removed from previous versions of the Mame rom sets.  For example, if you had the .120 rom set and the .120 rollback set you can build *any* previous rom set using clrmamepro.  You may still be successful enough for the games that you want to run, but there will still be many roms that you cannot rebuild without a rollback set.

The .119 rollback set that I have has a total size of 2.26 GB.
