I'm really sorry about the double post, but some guy I've never heard of on kodewerx made a code for geometry wars, and I modified it and made a few versions. here:
By Thnatos the Loonie:
Press L+R+Select for 1 Million Geoms
94000130 FCFB0000
021AAF24 000F4240
D2000000 00000000
Press L+R+Select for 100,000 Geoms
94000130 FCFB0000
021AAF24 000186A0
D2000000 00000000
Press L+R+Select for 10,000 Geoms
94000130 FCFB0000
021AAF24 00002710
D2000000 00000000
Press L+R+Select for 1,000 Geoms
94000130 FCFB0000
021AAF24 000003E8
D2000000 00000000
This code was found on an unknown chinese board:
Press Select for 9 Lives and 99 Bombs
94000130 000003FB
1231D05C 00000009
1231D040 00000063
D2000000 00000000
I used it to put together this template:
Set Lives to (X) and Bombs to (Y) (Start+Select)
94000130 FFF30000
1231D05C 0000000X
1231D040 0000000Y
D2000000 00000000
Using this template, I was able to divide it into 2 sections, and make codes using that:
Set Lives to Three [SELECT + RIGHT]
94000130 FFEB0000
2231D05C 00000003
D2000000 00000000
Set Lives to Five [SELECT + RIGHT]
94000130 FFEB0000
2231D05C 00000005
D2000000 00000000
Set Lives to Seven [SELECT + RIGHT]
94000130 FFEB0000
2231D05C 00000007
D2000000 00000000
Set Lives to Nine [SELECT + RIGHT]
94000130 FFEB0000
2231D05C 00000009
D2000000 00000000
Set Bombs To Three [SELECT + LEFT]
94000130 FFDB0000
2231D040 00000003
D2000000 00000000
Set Bombs To Five [SELECT + LEFT]
94000130 FFDB0000
2231D040 00000005
D2000000 00000000
Set Bombs To Seven [SELECT + LEFT]
94000130 FFDB0000
2231D040 00000007
D2000000 00000000
Set Bombs To Nine [SELECT + LEFT]
94000130 FFDB0000
2231D040 00000009
D2000000 00000000
From an unknown chinese message board:
Press Start+Select for
94000130 000003FB
1231D05C 00000009
1231D040 00000063
D2000000 00000000
I don't know what you'll do about credit for that chinese board, but You should give credit to Thnatos the Loonie, and... well, I deserve a tiny bit of credit for assembling the template and the codes and modifying Thnatos' codes.
EDIT: well, I just found the site and I guess you should give credit to "ymh". Take a look:
