This is another great title which was released by Konami which people of the generation still love to this day. For anyone who had this for the original console and had friends come over, this was a 2-Player game favorite by all means. The game had a decent challenge and replay factor and was a lot of fun!

Here is a hack that adds an options mode for the title screen with several functions.

v1.13 changes:
- Changed "ULTRA" to "KONAMI" at the credits sequence.
- Fixed the ending sequence bg graphics when using the patch along with the bugfix & polish hack (compatibility).

v1.12 changes:
- Changed the Ultra logo to the Konami logo on the title screen.
- Added "Mania" difficulty setting.
- Added "Fighting" setting. Old = original game, New = rebalanced hp for enemies. Set "new" as default.
- Made it so enemies don't have invincibility frames when attacked when using the "new" fighting setting.
- The special attack does 50% more damage in the "new" fighting setting.
- Redesigned the options screen.
- Moved the "nesrocks.com 2021" credit into the options screen.
- Difficulty settings now also affect the enemies' aggressiveness.
- Difficulty settings now also affect enemies' starting hp if using "new" fighting mode.
- Improved how scrolling works. Standing on the right side of the screen causes an auto scroll to take place. The point at which a manual scroll happens has been moved slightly to the left for a better experience. So now the screen is divided into 3 areas, as far as scrolling is concerned, instead of the original 2. No scroll, manual scroll and auto scroll. Originally it was just no scroll and manual scroll.
- Added compatibility to the "TMNT II - The Arcade Game Revamped" and to the "TMNT2 - Bugfix & Polish" hacks. First apply the revamped patch, then the bugfix patch, and then the options mode patch.

v1.0 changes:
- title screen and options menus can be controlled with the original select button, but also with Up/Down.
- title screen and options menus can be confirmed with the original start button but also the A button.
- options mode with sound test for all the music in the game.
- options mode for selecting number of lives (0-9).
- options mode for selecting number of continues (0-9).
- options mode for selecting the difficulty mode.
Normal = original game.
Hard = you take double damage from all sources.
Easy = you take half damage from all sources, to a minimum of 1 damage.
