Mortal Kombat 3 (Genesis)

Like the SNES version, but it has a lot more Kombat Kodes.

Error Handler
A handler for various exceptions is built into the game. This will display information on RAM / variables at the time of the crash.

Other error handler text:

Read Write Not Instr User Data User Program Supervisor Data Supervisor Program CPU Space (Unassigned, Reserved) Reset Reset Bus Error Address Error Illegal Instruction Zero Divide CHK Instruction TRAPV Instruction Privilege Violation Trace LineA Emulator LineF Emulator Format Error Uninitialized Interrupt Vector Spurious Interrupt Level-1 Interrupt Level-2 Interrupt Level-3 Interrupt Level-4 Interrupt Level-5 Interrupt Level-6 Interrupt Level-7 Interrupt Trap-0 Instruction Trap-1 Instruction Trap-2 Instruction Trap-3 Instruction Trap-4 Instruction Trap-5 Instruction Trap-6 Instruction Trap-7 Instruction Trap-8 Instruction Trap-9 Instruction Trap-10 Instruction Trap-11 Instruction Trap-12 Instruction Trap-13 Instruction Trap-14 Instruction Trap-15 Instruction Level-4 and Level-6 Interrupt will never be triggered because they correspond to the horizontal and vertical blank interrupts, respectively, technically making those unused.

Sound Test
Press A, C, Up, B, Up, B, A, Down at the main menu to enable a cheats menu with a sound test function.

Unused Bio Screens
A bio screen for Smoke was planned, but the text was never written, so it just uses Kano's bio text. Use the PAR code to see it during the game's demo mode.

More interestingly, the string "- MOTARO -" appears with the rest of the bio text! Like with Smoke, he doesn't have an actual bio. Unfortunately, since Motaro doesn't have a Versus picture, the game will crash before this text can be displayed.

Ending Text
The last line from the game's ending is never actually seen in-game. This doesn't appear in the arcade version either. Ending text is at : SHAO KAHN IS NO MORE YOU ARE THE MK3 CHAMPION YOU DONT SUCK
