i've noticed a "cheats" option in the menu listing through the hex editor however this game is evil and refuses to let me see it
looks like to me theres something with the scratch pad
as i could not find anything period for it no way to try and slip into it any help would be appreciated.

I just backtraced the "menu1 cheats" label. I poked the RAM address referenced in the ASM, that was set to load a value of 1.

Cheats Option Unlocked (main menu)
3008CC44 0001
Note: You'll be able to select any planet and toggle debug mode (the Cheats option in cheat menu). The "Cheats" option enables the following features (that I noticed):

Infinite Lives
? info (Gold text; far left of screen)
? set to 100 (Gold text; far right of screen)
Complete Level (press Select on Pad 1)
Kill Enemies (press L2+R2 on Pad 1)

Good teamwork. You guys are finding quite a few debug cheats.

Woah, from those screens that looks like it'd be a fun game to play.

Hybrid, if you want to see the build info of the game, goto this address in memory (ASM): 8006BE98 (MAIN). My copy had the following:

That's not the entire routine; just the necessary info to show.

This code auto activates the "Cheats" option, after entering and exiting the "Credits" option. I set a breakpoint read on the "Cheats" address, and it is read in the Credits screen ("set" to 1). There is either a button cheat to enable it here, or it's unlocked after beating the game (unknown requirements).
