No.06529 MetalliC Developer Aug 10, 2010, 16:47	Yes,I have 1GB of RAM, and a lot of pagefile space. But this is something new in 139, MAME .138 load gd-roms without any problems.

No.06531 MetalliC Developer Aug 10, 2010, 23:40 edited on: Aug 10, 2010, 23:48	this is sad news, MAME debug build was useful tool for getting encrypted/decrypted dumps. PS: just wondering, why I can run MSVC10 + other naomi emulator (or two) + a lot of docs/pdfs in background, and able normal play/debug games (also from CHD)?
No.06532 Haze Senior Tester Aug 11, 2010, 01:01	In short MAME will allocate the memory needed for a fully populate maximum capacity DIMM ram board as part of the device. This amount was increased to accommodate the recently added Chihiro CHDs, otherwise they will crash when attempting to decrypt the file. It's not optimal, and the reality is most Naomi games don't need such a fully populated board, however, for the time being it's not considered a priority to specify it per game. I don't consider it a bug because it falls under the usual performance / system requirements bracket and I wouldn't say expecting 2gig of RAM was unreasonable when the system needs upwards of 20ghz to emulate properly with the current driver ;-)
