# Helios

A Java-based multi-system emulator mainly focused on Sega 16-bit systems.

Initially created as a Sega Megadrive/Genesis emulator and then evolved to emulate
the following systems:
- Sega Megadrive/32X
- Sega Master System/Game Gear
- Sega Sg-1000
- Colecovision
- MSX v1
- NES

## Performance
 
Sega 32x: The target is a modern mobile cpu capable of boosting ~4Ghz 
(ie. [AMD Ryzen 5 PRO 5650U](https://www.amd.com/en/products/apu/amd-ryzen-5-pro-5650u)),   
this should allow perf close to 60fps for most titles, YMMV.

# How to Run
Requires java 21+ installed.

Get the most recent zip file from the download section,  
for example `helios-19.1108.zip` and extract to a folder.

## Windows
Double click on `launcher.bat`

## Linux
Open a terminal and run:  
`chmod +x launcher.sh`  
`./lanucher.sh`
