r32466 Monday 29th September, 2014 at 18:08:35 UTC by Fabio Priuli

(MESS) saturn: made RAM / Backup RAM expansion internal slot options. you now mount these with the -cart media switch, i.e. for instance  mess.exe saturn -cdrm ddsom -cart ram32 or  mess.exe saturn -cdrm draculax -cart bram16 and not anymore using the -exp option. [Fabio Priuli] out of whatsnew: this prevents users from passing conflicting setups like "-exp ram32 -cart kof95", etc. these would have lead to unpredictable effects, depending on the order of the option (and whether they were set at command line or inside ini files)
