Cheat Mode
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.
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.
Memory Cheat
Start up a "Trainer" program such as Magic Trainer Creator. In the game, make sure lasers are at 99. ALT-TAB or ALT-ESC out of the game and do a search of the game's memory for the hex string 00 7a 43 00 00 00. The one you want will probably be the last one listed. Freeze the bytes containing the 7a 43. Be sure to unfreeze before loading a saved game or else the game will crash. Since this location will always change when a saved game is loaded, it is a lot of work to keep lasers frozen at maximum. Editing the saved game as above seems easier.
