### Game files organization

The engine requires the "Data.rsdk" from the different games.

The folder organization is the following:

```
└── roms\
    └── sonicretro\
        ├── sonic1\
        │   └── Data.rsdk
        └── sonic2\
        │   └── Data.rsdk
        └── soniccd\
        │   └── Data.rsdk
```
