Nothing specific. I've been very busy with work and life, and have had very little time to work on any big projects.
I (of course) have a big project that is basically rebalancing classes and abilities, and eventually making battles less frequent and more interesting.
I would like to keep working on bugfixes, but a lot of them require more thorough rewrites. For example, all the equip bugs in battle (Thornlet, Mirage Vest, Mix bugs, a few others) can be fixed by rewriting the recalculation function to take into account stuff. It's a larger undertaking than it seems at first blush though.
I would love to do more thorough work on understanding C1 and graphics/animation in general. That's not really a romhack though, just information gathering. It's been a long time since I've looked at any of that. Specifically, I really want to get a handle on window drawing.
