Problems with multicarts

[Arcus87]

Many of roms doesn't launching or writing errors (often problem - Game has crashed - Invalid OP code cpu crashed) Maybe the problem in roms, not in Mesen? The problem is that there 457 roms , in Multicarts Collection.7z from GoodNES

A big thanks will be if you check and fix games.

Support for some new mappers has been added since you created this issue (mostly UNIF mappers), which probably fixes some of the multicarts.
There are still about ~30 UNIF boards I need to add support for, so it's possible some multicarts still do not work properly.
I just created #128 to keep track of all issues with unlicensed games. If you have any specific multicarts that don't work properly and use a mapper that Mesen supports, please post a comment in #128.
Thanks!
