Slowdown Super Mario World 2

[MarioSuper]

Hi!
Play Super Mario World 2 - Yoshi's Island and saw slowing. For example Chapter 3 Level 1 with monkeys. (snes9x 32)
On the emulator SnesGT no slowdowns.
Is this a bug?
thanks

could you provide NSRT info of the ROM you were using (or perhaps the CRC32 number)?

In addition, what version of Snes9X are you using? (posting if it's 32 or 64 bits without a version number doesn't help..)

That slowdown is happening because of the monkeys swinging across the trees behind Yoshi and the monkey spitting seeds at Yoshi. Whats weird it does not happen in the ZSNES version.

Must be some slowdown problem, The slowdown happens in both 32 & 64 bit versions of Snes9x 1.53.

This is probably in part to the inefficient Super FX emulation core that Snes9x currently has. MarioSuper, what hardware specifications do you have on your computer? (CPU, RAM, OS, etc.)

So it has something to do with the Super FX emulation.

No way to fix it?.

ATM, no. We're working on it though...

To get this clear, are you also involved with the Snes9x?.

So far Snes9x is one of the best Snes emulators, just with some small problems.

I am not directly involved with development, but I can typically fix common problems that people encounter and such.

Really?. if so what will it take to fix those slowdown problems.

it'll take two things.

first, it'll take the developers spending their personal time (outside of job, family, and the like) to refine the emulation core.

second, it'll take some patience from the end users - if it were a trivial issue, it would've already been fixed (or you would've fixed it yourself and shared the code with the community).

I'm happy the makers fix problems with Snes9x.

Sadly ZSNES will never be updated anytime soon and 30% of games on ZSNES are glitchy or don't work.
