It is an issue with freeshop, related to 'screen sleep' feature.... Great work to you arc13 and lets not forget the original creator.
You certainly got the cream of the crop, so to speak, in choice of projects to continue and have shown tenacity and grace in taking it on. All respect and appreciation from myself and many others.
Not to take anything from your work or undermine your ability, but do remember there are many talented minds here on gbatemp to bounce ideas around with and help troubleshoot if you need a hand. Don't be shy in moving things forward with assistance if needed, understanding that it does not take from your fork, nor does it questions your ability or takes anything from the reputation and appreciation you deserve in taking this on.
Good work mate.
