This game has no less than twenty five one-hit kill collision checks. Imagine yourself sitting there in an air conditioned room making all those manual edits using Action Replay…and then you have to know all the offsets…and the offsets will change on different machine configurations. Forget it.
Load the game up in WinUAE and make sure the game has started proper so you are actually in the game, then make a save state…but no so fast. You will notice under the save game File name prompt it says ‘WinUAE snap shot files (*.uss)’, left click that and select ‘Uncompressed (*.uss) and then click save.
Now, deep breaths, you won’t be expecting this – open the save state file you created with your trusty hex editor (e.g. XVI32) and replace all occurrences of the following string
29 7C 00 00 00 01 84 12
29 7C 00 00 00 00 84 12
Save the changes you made in the hex editor and close it off. Now, go back to the emulator and load the save state.
Yes! Now there are no more one-hit kills, enemies safely pass through- you’re invincible!
