Request For Zero Wing (Genesis) GG Code

[Whipon]

The ram addresses for the level 4 weapons are:
FF0BBA:84 This one sets the level 4
FF0BCC:0E0C This changes the left side shot to the level 4 one. Otherwise it graphics are messed up.
FF0C0C:0E0C Same as above, but right side shot.

The ram address of the weapon level (the one gained by normal powerups) is FF0137.
Set Weapons at Level 3,
FF0137:03.

I'll see If I can make a simple code version. My code is a 3 codes, because of the following:
BTYA-A6ER This one changes the graphics of the side shots to the ones of the 4th level. Otherwise the side shots graphics are messes up. (Only works at the start of a new game).
The remaning two pokes the value of FF0BBA to 84:
TTMA-BA4A
TAMA-BACC

I have a new idea, I'll try to make a shorter code.

I found a nice way to do it.
It seems the routine writing all the values required to get level 4 needs to be executed, otherwise some graphics are messed up, like the side shots and the laser shot.
Here you go:

Spread Powerups Worth Level 4,
AEPT-AACN

Laser Powerups Worth Level 4,
AJPT-AACN

Homing Powerups Worth Level 4,
ANPT-AACN

Speed Powerups Worth Level 4,
ATPT-AACN

Only downside is that you'll loose the choosed item. Its best to sacrifice the speed powerups and use Tony codes for the speed.

You can also use in combination with
Start With Weapons at Level 3,
A2YT-AABA
To get full power from the start. Or you can simply collect powerups until you have the desired level.
