Prehistoric Isle in 1930

Prehistoric Isle in 1930 is a shoot 'em up about dinosaurs living on an island chain near the Bahamas during the Great Depression. Mmmhmm.

Programmer Messages#

There are three hidden messages and a small piece of uncompiled C code starting at 0x004A8 in the main CPU:

Prehistoric Isle Software System. Version 1.12     

PROGRAMMED BY TAKOGUTI KAMEN OOI AND ITSAM MATARCA.

THERE IS A WHITE DOG. VERY INTERESTING.            
(SHIROI INU GA IMASHITA. OMOSHIROI.)

/* Error /*                                        
error()
{
    printf("ERROR !\n");
}

Regional Differences#

FBI Screen#

All versions feature the "SNK Presents" screen during the attract mode, but the US version has an additional one shown before it: the blatantly obligatory FBI "Winners Don't Use Drugs" screen that was common of the era.

Title Screen#

Japan	Europe	US	Korea

High Scores Screen#

International	US

In addition to the standard "Winners Don't Use Drugs" screen, the US version also (redundantly) adds the same text to the high score and gameplay demo screens, plus another "INSERT COIN" message and helpful arrows.

Credit Slot(s)#

Like some Alpha68k (e.g. Gang Wars) and SNK68k (e.g. Street Smart) games, in all versions of the game sans the US one, players share one credit slot. In the US version, each player has its own credit slot.
