Patch Anex86 to allow more than 14MB RAM ttp://forum.softhistory.org/showthread.php?tid=28
Basically, at three seperate places (startup, going to settings, changing ram value in settings), Anex86 checks the amount of RAM given to the VM (in the settings this is a DWORD of the amount of RAM in bytes), if it's 0xE00000 / 14680064 bytes (14MB) or over, it sets the value to 0xE00000.
However, the emulated PC-98 works fine with RAM over 14MB.
So, you basically need to open anex86.exe in your hex editor and make a small 3 byte patch. For Anex86 version 2.77, patch 7E to EB at offsets 0x4bd05, 0x4a5fd and 0x4ccbe. For Anex86 version 2.78, patch 7E to EB at offsets 0x49d89, 0x4b706 and 0x4c87a.
After you've done this, you can set more than 14MB RAM in the settings, and the emulated PC-98 will work fine.
EDIT: Apparently, the OS will only see 32MB RAM. Still more than 14MB.
