Super Mario Bros. 3 and Kirby's Adventure sprite layer error and Audio issue

any time smb3 or kirby is loaded into jsnes, the sprite layer will scramble and also wiith the audio issue, any specific job will freeze the gameplay for a bit and speed up for a second...

Start by reproducing the sprite-layer scrambling and audio behavior in jsnes with Super Mario Bros. 3 and Kirby's Adventure. Trace the emulator paths responsible for sprite rendering and audio timing, since no files or tests are named. Done means both games render sprites correctly and gameplay no longer freezes or briefly speeds up during the audio issue.
