A "Loading" screen was added to the emulator around the time of version 0.7 or such. Before then, ROMs used to load very quickly. Since then, a selected ROM takes quite a long time to load and start. The "Loading" screen displays a percentage of completion, and the progress is slow. Is the slowdown that was introduced unavoidable and necessary for the better emulation or is this unintended and potentially improvable?

Can confirm this. Updated recently and noticed the slow loading times. First thought this has something to do with save states but had them disabled.

There has always been a loading screen, but the percentage was added in 0.8 IIRC. I tried to make it only update after every large chunk, but I suppose it's possible that the chunk size is still too small.

I can't comment on the back-end of how things work since I can only take note of the cosmetics of the "Loading" screen. However, when it was added, it coincided with a very marked slowdown in ROM loading as well. Again I cannot comment on whether the screen itself is linked to the degradation, I would just like to note that when that was done, it was accompanied by a very big degradation in ROM loading performance and it has been that way ever since.

Yeah, I'll look into it later today.
