Capcom is known for doing this and the games having these exact problems (framerate drop, wall jumping issues etc). The last megaman legacy collection was nearly unplayable because of it. They knew the issue was the emulator running it, and they refused to fix it. Then they release two new legacy collections and they have the same problem, and no one was surprised. Good thing my phone's emulators have no such issues.
