I tried to address long standing requests and newly arisen bugs. In the process, I found I really don't enjoy the game anymore, I've played it way too much in 2012-2015. So I tested the changes quite minimally. I'll fix bugs reported over the coming weeks.

As for the changes... here is what I found and what I did/did not do about them:

1) Crashing on vanilla DS:

I was really surprised to see this happening. As I can't roll back to older versions of the game, I cannot tell whether this was always there or not. I'm sorry I didn't believe the reports.

It turns out that some of the API required to implement the filtering functionality of the mod is missing from the vanilla code. It is implemented (redundantly and independently) in both RoG and SW. I have filtered out the offending lines to avoid crashes, at the cost of removing the corresponding functionality when running vanilla DS.

2) Supporting Scythe mod:

As it appears to be a very popular mod and two users asked for it, I looked into the issue. Unfortunately, Handymanness requires hacking into the DS action button handler much deeper than foreseen by the modding API. I could not come with a way to move back from this stance, i.e. make Handymanness comply with the modding API's limitations and therefore compatible with other mods that also modify the action button handler.

3) The future of the mod:

Did I forget anything? Time for requests, new or renewed! As I just got the code into my head again...
If anyone would like to inherit the maintenance and continued development of this or any other of the mods I wrote, please contact me. I'm happy to help.

Enjoy your playthroughs! I had so much fun with this game, it is kinda sad it ran its course. It is one of the best games I've ever played.
