Disabling layers/sprites in PSX?

First of all, a big "Hi" to all the community members.

I am a mugen creator and a sprite ripper. I am interested to know if there exists a plugin to disable layers or sprites in PSX emus, or if anyone is coding a new plugin with this features

Using Pete's plugins, I can disable sprite masking, so it's easier for me to rip them, but there are some frames in which the sprites become squeezed.
Also, using save-states tricks, I was able to get some background layers moved, therefore making it easier to get a perfect rip, however, using this trick I get pallette problems.


Thanks in advance.
