Joe And Mac - Invincible God Mode Edition (W) (Genesis) Romhack

Author: God Mode

Joe & Mac, known as Joe & Mac: Caveman Ninja in Europe and Joe & Mac: Caveman Fight (ジョーとマック戦え原始人) in Japan, is a 1991 arcade beat em up, action game ported over to the SEGA Mega Drive/Genesis. It is a port of the Data East arcade game of the same name. It was developed by Eden Entertainment Software (under contract to Elite Systems).

Publishing licenses of this version were granted to Takara in North America, Tec Toy in Brazil, and Codemasters in Europe. While the game was released in North America and Brazil in early 1994, the European version never materialised so PAL regions missed out yet again.

The original retail game is extremely difficult to pick up and play as you don’t last long on one single try getting hit by all sides of the screen and the bosses tend to take way too long to die. So this ROM patch changes all that to make the game extremely easy and enjoyable so you can just breeze through it solo or with a friend as it’s a 2 player game.

ROM CHANGES:

Invincibility.
Bosses are easier and much quicker to kill.
You can select 15 lives and 9 continues in the Options Menu.
Skip levels – Pause the game and hold A + B + C and press Start.
Time to continue is infinite.
Infinite lives.
Most attacks do more damage.
Pause the game to get the Wheel Weapon.
ROM header is updated with new date.
Works in all regions with no slow music for PAL systems.

INSTRUCTIONS:

Inside the ZIP file you’ll find the IPS patch, it is Lunar IPS format and simply needs to be patched to the USA version of Joe & Mac.

NOTES:

1. The original unedited retail ROM of this game is very hard to play as the difficulty is quite high! So this ROM patch is a treasure to those who just wanna have fun and breeze through the game.

2. This game was never officially released in PAL regions but if imported from USA, it plays perfectly normal with no slow music or glitches.

3. The game is somewhat listed on various sites as an ”Action Platformer” but I see the game more as a comical, cartoony beat em’ up. There is no actual platforming other than a few high jumps to make as you’re constantly walking around shooting at enemies which is more like Streets of Rage or Final Fight.

Enjoy this banger of a game!
