But as Qbix said there's no reason to raise the limit if
nothing uses it.

Some games in MAME for DOS needs more than 64 Mb. Bubble Bobble Memories didn't work in MAME (DOS 6.22), but it doesn't make sense playing MAME for DOS in a DOS emulator... there are versions of MAME for any OS you can think of.

glad that redgaurd myth got cracked.
Couldn't believe that game would need 128 mb memory.

Nobody was claiming that Redguard needs 128MB, but rather that it may be able to take advantage of that much.

Then it's not worth adding it as it might create problems
with games that can't handle it.
