Looks great 
And that effect with 'crazy rain' (tweaking some rain-related values?) was funny 
Currently using 80% CPU time with the bulk of the CPU-heavy work being done, and with some room for optimisation. Tile drawing is still a bit too slow; 45% CPU time with diagonal movement, while I should be able to do it in 30-35%. And there’s the 30 fps animation 60 fps motion trick I mentioned earlier as well, which also accounts for some 10%. So I think performance-wise it’ll be allright on the Z80.
I got a nice CPU usage profiling script going in openMSX by the way:
x: Total cpu usage per frame (81.22%)
0: Updating player position (01.82%)
1: Updating map view position (01.81%)
7: Updating sprite patterns (02.66%) (animation works!)
2: Updating sprite attributes (08.62%)
3: Updating sprite colours (19.72%)
6: Setting base table address updates on interrupt (04.37%)
5: Submitting draw context (00.12%)
4: Drawing new map tiles (44.42%)
As I said before, it looks super pretty and smooth. I'm starting to wonder now if there are already some concepts for game mechanics and maybe even a story.
I have some ideas written down about the outline of the story from intro to outro, but it’s still very rough. In terms of game mechanics, I’m thinking of pushing some boxes, unlocking doors in certain combinations / orders, finding objects, etc. That kind of puzzles.
You're scrolling way too fast for an rpg imo, those usually walk at snail pace . slow it down and you could probably use less cpu time.
Oh right my bad, I just watched some vids
I think its because of the lack of walking animation that makes it looks floaty /fast
Btw thanks for pointing me to those profiling scripts, I'll test them with my own scroll routines (which I showed to a few ppl during the Beuningen fair)
