What is the scientific reason that Sonic Pocket Adventure / SPA enters debug mode when using an emulator? I have the actual hardware and pressing Options at the SEGA screen does not work. It might be that debug mode is removed from my build if there are others capable of entering debug mode without an emulator. So are there? Debug mode's activation is often cited as an emulator bug. Did anyone look into it further? The most prominent Sonic Pocket Adventure hacking was done by Rolken in <a href="http://forums.sonicretro.org/index.php?showtopic=8262" target="_blank">this</a> thread, but being in 2006 it seems his efforts are long dead and so are the links.
