Mario Bros. 6-8-88

This is a late WIP of Mario Bros. that was found on a hard drive. While the graphics are almost exactly the same, the gameplay and music are still being worked on. The music is much slower and far worse than the final version. The movement of all the objects in this version is also very choppy making the game much more difficult than they should be. There's also a strange white object on the first phase which is also seen in other prototypes being developed by ITDC which doesn't appear to do anything if touched. This might be some sort of trademark from the developer.

Differences

The music on the title screen is different much Much slower. The tune appears to be roughly the same though.

The demo is completely different and shows the first phase instead of phase 10 and 13

The title screen option selections are laid out differently. Instead of selecting the difficulty and number of players by highlighting it with the cursor there are four options that are selected by moving the icon next to it. These options are laid out similarly to the NES version with choices for One/Two Players and Game A/B. Game A seems to be similar to Standard difficulty while B seems to be either Advanced or Expert difficulty.

The font for the HUD is different. The letters are larger as well

There is an odd object to the right of the vines on the first screen. This object also appears in prototypes for other games that ITDC developed such as Mario Bros. and Donkey Kong. If touched it makes a brief sound and then disappears. This might be some sort of developer trademark.

The title screen logo is missing the (R)

During the demo the number of men shown in reserve is 0 instead of 1

The life counter uses a different symbol

The copyrights on the title screen are different

All the music during the game is different and slower. Generally more rough and unrefined sounding.

The movement for the graphics isn't as smooth and is a bit choppier. This makes precision jumping more difficult.

Mario jumps slower

Most sound effects are different

The PHASE # text is missing at the beginning of each level

The bottom of the POW block is miscolored on the bonus stage

The timer on the bonus stage runs much slower

The message for getting all the coins on the bonus stage is wrong. Instead saying 'Perfect 3000PTS !!' it says '3000PTS !! Perfe'.
