Sonic Genesis for Master System v1.05:
This is my attempt to make the Master System version of Sonic to look and sound more like the Genesis/Megadrive version. The graphics of all zones have been replaced, including sprites. The music has been replaced as well. 
I like the gameplay of the Master System version, so i kept the gameplay exactly the same as the original Master System version.


How use this patch:
The ips patch must be applied to the Master System version of Sonic the Hedgehog
- Unpack both the original rom and this patch
- Use Lunar IPS to apply the patch to the rom (it will overwrite the original rom)
- Play!
