Original issue 357 created by autofire372 on 2013-08-12T20:25:03.000Z:

What steps will reproduce the problem?
1. Start the emulator.
2. Set Lock-on option for Sonic & Knuckles, with a verified sk.bin in its proper directory.
3. Load verified Sonic 3 rom.

What is the expected output? What do you see instead?
I expect Sonic 3 & Knuckles to boot; instead, S&K boots.

What version of the emulator are you using (official, SVN revision,...)?
Official release, version 1.7.4

Please provide any additional information below (Emulator settings, Console
setting,...)
I am using a Wii with system menu 4.3U and the latest Homebrew Channel installed.

I would like to note that I tested the lock-on feature with another rom (Zero Wing (E), if anyone needs to know), and it also simply loaded S&K instead of booting to Blue Sphere.

There was a regression caused by SRAM handling changes in 1.7.4 which screwed SRAM support in games that use ROM/SRAM switching but also impacts lock-on switching.

It should have been fixed by r805
