CHR Viewer

Enable Game Genie code PTUAOYZY, then go to the Password screen and enter the password for the Sound Test. You'll be taken to the CHR Viewer instead. Here's what the controls do:

Left / Right - Increase/decrease the numbers by 2. Up / Down - Increase/decrease the numbers by 16 in Hex (i.e., 00 to 10).

Stage Select

Enter Game Genie code PENEXTAA, then choose the Password option on the title screen. Not only can you select the stage, you can also select different parts of the stage as well. Once you select your team members, you'll start the selected level.

NOTE: Selecting parts 3-5 of Stage 6 will crash the game after the boss cutscene, as they don't exist.
