Sound Factory (Japan) (Prototype)
- - LuigiBlood

A prototype of Sound Fantasy, when it was still named Sound Factory. Presumed to be the build from the Nintendo Shoskinkai 1993 event.

There are two cartridges known to exist with the exact same ROM data written. Was found by steven78, then sold both cartridges on eBay. Was bought by an anonymous buyer for about $7,000 who dumped the cartridge using a Super Wild Card DX2, and sent to LuigiBlood for release. (ROM dump release date: 2015/04/07)

Contains Pix Quartet (based from Music Insects), Beat Hopper and Star Fly. Does not seem to have any traces of Ice Sweeper.

Pix Quartet has a few bugs with a few insects not playing notes when crawling over colored pixels.

Mighty Max (USA) (Demo)
- - Matthew Callis

A demo of Mighty Max as a 2 player game, but it auto plays both players for you. No intro screen, just the game playing itself. Not much to say, it doesn’t play long and loops. Looks like it might have been for shops to just leave on loops or to take screenshots from, etc.

It has an internal title of MIGHTY MAX DEMO.

Denz Traffic Panic (Japan) (Spark World Prototype)

Denz Traffic Panic (Japan) (Spark World Prototype)

デンズ トラフィックパニック (スパーク・ワールド プロトタイプ)

This is an early version of Spark World, a fun Super Bomberman clone where the players are cars and everything is automotive themed.

It’s close to being finished, I only noticed the lack of a difficulty selection and a few graphical changes in the story selection, the player and the player score area- outside of the title screen overhaul due to the name change.

Titles - Prototype / Final

The title screens are similar but the logos are entirely different, the prototype logo looks more “fun” to me. The barrel obscured by the menu had changed to a battery, and STORY GAME replaces NORMAL GAME in the final.

Some backgrounds have very slightly been adjusted, for the better. Here we see the repeated background changed from TRAFFIC PANIC to SPARK WORLD.

Story In Game

Lots of changes in game, the car looks happy in the prototype, power up icons are slightly different, the border of the player box has changed, and in the prototype player 2 doesn’t look defeated.
