By some reason that I don't know the patch of DRAGON QUEST 1+2 was CORRUPTED.
It needs to be downloaded again.
I was generating the patch with SNESTOOL and it produces some kind of incompatibility when expanding this ROM. I have generated it with LunarIPS; anyway, it works with both tools now.
Simple sprite hack to change Simon’s sprites to the ones from CV Lords of Shadow - Mirror of Fate. Other sprites like the whip upgrade and big heart were changed to look more like Mirror of Fate as well
