Eliminate Down Remix Mode - ROM Hack for Sega Mega Drive

This ROM hack introduces a wide range of enhancements and a brand-new Remix Mode, all accessible through the in-game options menu. Designed for both casual players and hardcore shooter fans, this aims to be the definitive version of Eliminate Down.

🔧 Hack Features

🎮 Controls

Selecting Control Type:

The control type is automatically detected at boot, for those with a 6 button controller that would prefer
the 3 button layout, holding the mode button when booting your console will detect a 6 button controller
as a 3 button one.

3-Button Controller

• A + B + C: Activate Barrier (Remix Mode only)
• A: Cycle ship speed

6-Button Controller

• X: Rear weapon
• Y: Vertical weapon
• Z: Front weapon

🆕 Remix Mode

Select Remix Mode from the Options menu to enable the following enhanced gameplay mechanics:

• Each of the three weapons can be powered up individually
• Weapon level increases every 3 power-ups collected
• Up to 3 power-ups are stored if the weapon is at max level
• Power-ups trickle down to the next weapon if current is maxed
• Collecting a power-up when all weapons are maxed gives +2000 points
• Dying removes 3 power-ups and 1 level from the main cannon
• Barrier is stored until manually activated by the player (max 9)
• Redesigned HUD shows weapon levels, stored power-ups, and barriers
• Continuing a game restores ship state (power-ups, score, and barriers saved at stage clear)

💾 SRAM Save Features

• Hi-Score and Mini Game High Score saved to SRAM
