Region invalidated problem

[ShimaPong]

In options -> search memory areas, if you choose "OFF" region then press "Shift + Delete Cheat", MAME crashes instead of "region invalidated".

I haven't had a chance to test this yet, but at around line 9179, change:

Code: Select all

static void InvalidateEntireRegion(SearchInfo * search, SearchRegion * region)
{
	memset(region->status, 0, region->length);

	search->numResults -= region->numResults;
	region->numResults = 0;
}

to

Code: Select all

static void InvalidateEntireRegion(SearchInfo * search, SearchRegion * region)
{
	if(!region->status) return;
	
	memset(region->status, 0, region->length);

	search->numResults -= region->numResults;
	region->numResults = 0;
}

I'll make a diff of all of these recent changes and submit it tomorrow night.

Thanks. I have confirmed that the crash problem is avoided with your fix.
