It’s the first ever ROM hack made by S.D.A. that is not a translation, although it is very simple. Here, the Jumpman sprite is changed to the Mario sprite from SMB1.

This was made from the simple fact that if you notice, the Jumpman and SMB1 sprites (at least the walking sprite) are really similar. Here are the only changes:

Original Jumpman sprite replaced with the SMB one (except for the climbing and death-lying sprites which were intentionally left as they are, while for when the player picks up an hammer the graphics are simply modified). Hammer powerup is now changed to the SMB1 style.

Two patches are available, one for the 1983 ROM and the other for the “Original Edition” ROM (the one with the additional “Pie Factory” level).

August 5 update: Even if this hack was a success, S.D.A. hated it and so he took it down.
