Hex Cheat:

In the PARTIDOS directory under the install directory, the files named PARTIDOS1.OEM, PARTIDOS2.OEM, etc. hold the player's health level, number of laser shots, number of pears. etc.

Open the file corresponding to the number of the saved game with either a hex editor or, even better, WORDPAD.

EDIT-FIND the string "PERSONAJEM" (without the quotes). Page down to the section called VIDA. The "ACTUAL" line is the amount of health (Max 250).

Several more pages under this is the section PERSONAJE_M. Under this will be found the following:

Superrayo = 9999999.000 (super laser)
Cantidad_Laser = 250.000 (laser shots)
Cantidad_Peras = 99.000 (pears)
Cantidad_Boomerangs = 99.000 (boomerangs)
Cantidad_Huevos = 99.000 (gork chick eggs)
Cantidad_Piezas = ?.000 (spacecraft pieces)

with their maximum values.

Notes:

Note 1:

If you change Cantidad_Piezas to the number of needed spacecraft pieces (or higher) for that level, the game will start the next level when you load the saved game.

Note 2:

There are two lines that say Superrayo = Set them both to 9999999.000 to get super lasers for a very long time
