Pengo 2-28-84

This is a later version of Pengo that still has several differences from the final. The nicer title screen from the earlier version has been removed at this point, but the earlier graphics for Pengo are still there. Some new features have been added to this version such as the different colored ice blocks, two player mode, and level select. The difficulty has also been adjusted so the Sno-bees are much slower than they were in the previous prototype. This version also keeps the older stage layouts.

Prototype Differences

Upon starting the game, Pengo's graphics on the title screen appears to have glitchy movement. This is because the initialization code misses a CLD command which clears the decimal flag. So all addition and subtraction operations are assuming BCD numbers (Binary Coded Decimal) and leads to wrong results.
