So apparently I need Fire Red v1.0 in order to progress in my hack. Is there any way to just copy and paste my maps and scripts over to a fresh rom for the same game? I really don't want to have to start all over
No, there's not really a copy + paste method. You can export your maps, trainers, etc out of your current ROM and insert them manually into your new game if you're willing to spend the time. That's unfortunate. If you'd like, you can post what your issue is with v1.1 and perhaps I can point to a workaround.
