I know im new, actually this is my second post, but i have learned alot ( especially from Lt.err…(gotta get his name). anyway i thought i might help you guys out with the “cheats” for gbdoom2.
1)To activate them either…
a)press tilde (~)
b)activate it in the options
And even then the only ones i know is god mode (IDDQD) and all weapons, all ammo, all keys(give all), just type those in when you get to the prompt and press enter.
P.S. If you want infinite ammo, thats also in the options
Happy Busting!

Janine: Would you like some cofee, Mr. Tully?
LouisTo Egon)Do I?
EgonTo Louis) Yes, Have some.
LouisTo Janine{evidentally confused})Yes, Have some.

Actually you can just type in anywhere cheats like
gozer(godmode)
vigo(godmode with ghostvision)
slimer(walk through walls)
egon(all guns and keys but be careful pressing no.1 will result in driving ecto 1)
Ray(All guns but once again watch out for ecto it's ver frustrating)
You can type those cheats anywhere

I forgot the ever so handy cheat Warpme## of coarse you fill in the numbers. this cheat is essential…
