Lua

Lua is a lightweight programming language usually used to extend other programs. In this case, I use lua in emulators to add new functionality to games.

Emulators with Lua (WIP)

Scripts

Power Blade

JDV1W.png
This script is intended to make the game a little more challenging and fun. Some enemies are modified, but the main feature is adding guest enemies. At the moment, you can add the eagles from ninja gaiden and the flying shells from megaman. The guest enemy positions can be saved and loaded with the script. Currently you will have to add them yourself, but I'd like to save several modification files in the future.

Changes:

Bionic Commando

This script lets the player select a rocket pack instead of the Bionic Arm. I've fixed a number of issues, but there may be some bugs, especially with the jump option.

Super Mario Bros. 2

Instant in-game character switching by pressing select.

— Changes:
— * Change character in game by pressing select
— ToDo/Issues/Bugs:
— * Pressing select when not in game can cause undesired effects, such as
— distorted graphics, wrong palette.
— * Luigi gravity isn't quite perfect
— * Some things may not change when switching, like root holding position .
— * Character switching can be abused in some ways, like continuing a
— princess float with another character, or switching mid-jump with toad
— to get a higher jump with Luigi. A good fix would be to make switching
— only possible on the ground, or have switching cancel a jump.
