The unique builds for this week are as follows:

A prototype of Death Duel for the Sega Mega Drive. Appears close to final. Contains some spelling and grammar errors as well as code changes.

European Club Soccer prototype (Oct 25, 1991)


A prototype of European Club Soccer for the Sega Mega Drive. No Virgin logo credit, lacks copyright on title screen, no "more options" option.

Growl prototype (Aug 26, 1991)


A prototype of Growl for the Sega Mega Drive. Still has the "EASY" difficulty option despite being removed from the US release. Built a few months before Japanese release.

Paperboy prototype (Oct 28, 1991)


A prototype of Paperboy for the Sega Mega Drive. Built two months before the US final.

Pat Riley Basketball prototype (Jun 14, 1990)


A possible prototype of Pat Riley Basketball for the Sega Mega Drive. Almost the same as US final, except for a one byte code change and different data at the end (possibly padding).

RoadBlasters prototype (Jun 27, 1991)


A prototype of Road Blasters for the Sega Mega Drive. Build date hints one month before final US, though header references Aug 1990.

A prototype of Speedball 2: Brutal Deluxe for the Sega Mega Drive. Lacks trademark on the Arena company logo before the title screen. Demo mode starts with a different timer.

Tommy Lasorda Baseball localization prototype (Apr 30, 1989)


A possible revision prototype of the Tommy Lasorda Baseball localization for the Sega Mega Drive. Either pre-US final or pre-PAL final. Contains additional code to control the Z80 bus in VBlank. The code is present in the PAL final but absent in the US final and JP original, however it could be a debug setting.

Turbo Outrun prototype (Dec 9, 1991)


A late prototype of Turbo Outrun for the Sega Mega Drive. Sound test tracks not named yet.

Miscellaneous ROMs

Just like last week, there are a few ROMs that can be considered “Altered Finals”, where the build itself is based off a final ROM but altered slightly for whatever reason. These ROMs have nothing that changes the game in any way, but are included here as an interesting curiosity.

The games are as follows:


This is the last part of this month's Final ROM archive release. We recently retouched all the entries that we have so far to include some general information on what has been discovered so far. In case you're just tuning in, here's a recap of some of the best ones in case you missed it:

As always, remember to keep tuning in sometime every week for more releases. And expect to see something different every month! Remember to follow us on Twitter, Facebook, and Youtube for the latest as soon as it all happens. Be sure to tell your friends as well!

Until next time!
