3 /5

This is a port of Sonic CD to the Sega Mega Drive, better known as v0.02, which brings the game to the standard Sega Mega Drive console. It contains the first two acts of Palmtree Panic featured in the demo, as well as Bad Future (Act 3) from prototype 510 and an incomplete version of Collision Chaos Act 1 Present (also from prototype 510). This homebrew incorporates a modern version of Lock-On technology, allowing a level to be saved to a custom PAK file before being added to the ROM.

Started on August 4, 2024, based on a disassembly by KatKuriN. This project won the Hexadecimal trophy for Best Technical Project, as voted by the judges at the 2024 Sonic Hacking Contest.

This port has the following features:
• Zones 1 and 2 of Palmtree Panic.
• NEW: R13D, including its boss ported from 510!
• Functional time travel.
• A Sega logo and title screen.
• New sound effects.
• Pause.

This port is not complete.
Some important missing features include:
• Time trial.
• Time travel cutscene.
• Music: Unfortunately, the complete soundtrack could not be translated in time for the Mega Drive sound chips, so you will hear tracks borrowed from Sonic 1.
• Good Future levels (you can't access them in the original demo anyway)
Most of the bugs present in the original demo remain, but some have been fixed thanks to the porting method.

These include the following:
• Sonic sprites have bugs.
• Time and rings disappear during time travel.
• Time travel does not work on rotating platforms.
• Any sound-related bugs that existed in the original version (The project now uses the Sonic 1 audio driver)
