Code: Game Code/ID : YVTE 7BAECEA9 For the fun of it, here are different versions of an infinite life code. I hope it will not confuse too many peoples... : 1) As it uses the C4 code type, this code will only work on the real AR v1.54 (or higher I suppose), the trainer toolkit (with the AR v1.52 or 1.54), and I guess NitroHax. 17 lines total. Code: Infinite Life * C4000000 00000000 00000054 000040E4 C0000000 00000003 C4000000 00000000 D9000000 0000003C D4000000 00000004 D6000000 0000003C D3000000 0209DA40 60000000 00000000 B0000000 00000000 DC000000 000040E4 60000000 00000000 B0000000 00000000 00000104 00000060 D2000000 00000000 * It should work for every warrior (tested with 3 warriors up to level 2). 2) The same code without the C4 code type, a bit longer (15 more lines, for a wooping 32 lines !) and less interessing to do, but that will work for everyone. Code: Infinite Life * 6209DA40 00000000 B209DA40 00000000 DC000000 000040E8 F2000000 00000004 62000000 00000000 B0000000 00000000 00000104 00000060 D2000000 00000000 6209DA40 00000000 B209DA40 00000000 DC000000 000040EC F2000000 00000004 62000000 00000000 B0000000 00000000 00000104 00000060 D2000000 00000000 6209DA40 00000000 B209DA40 00000000 DC000000 000040F0 F2000000 00000004 62000000 00000000 B0000000 00000000 00000104 00000060 D2000000 00000000 6209DA40 00000000 B209DA40 00000000 DC000000 000040F4 F2000000 00000004 62000000 00000000 B0000000 00000000 00000104 00000060 D2000000 00000000 * It should work for every warrior (tested with 3 warriors up to level 2). 3) Asm hack. Works on anything that holds the AR code handler, and is way faster to execute than any regular code. 14 lines. Code: Infinite Life *
023FE074 012FFF11 E0000000 00000058 E92D0007 E3A02060 E59F0044 E5900000 E3500000 0A00000C E2800901 E59010E8 E3510000 15812104 E59010EC E3510000 15812104 E59010F0 E3510000 15812104 E59010F4 E3510000 15812104 E8BD0007 E12FFF1E 0209DA40 023FE074 E3520003 * It should work for every warrior (tested with 3 warriors up to level 2). |

what's the use of this C4 one? |

| Post subject: | Re: [NDS] Operation Vietnam [US] [AR] |
The C4 code type (as I explained in the AR codes types thread) makes offset = address of the C4 code type in RAM. With it, I can then choose to modify any codes 'on the fly', as I know exactly at which distance from(/to?/of?) the C4 code type they are stored. In the code I created for Operation Vietnam, I used it to modify the data of the DC000000 000040E4 code type. In that game, the pointers to the 4 players life value are at [pointer + 0x40E4], [pointer + 0x40E8],[pointer + 0x40F0], [pointer + 0x40F4]. As you can see, I used a loop (C0000000 00000003), and two C4 codes type (one before the loop, one in the loop). For the one inside the loop : When the loop is executed at first, the C4/D9/D4/D6 codes combo will add 4 to the value of the DC000000 000040E4 code (the D9/D6 codes read/write to offset + 0x3C, ie. [second C4 code type address + 0x3C], which points to the data of the DC code type), which will become 0x000040E8 (=offset to reach the pointer to the first warior). The second time the code is executed, another 4 is added, and it becomes 0x000040EC (=offset to reach the pointer to the second warior). Same for the third and forth time the code is executed. So when the code has been fully executed, the DC code type looks like that in RAM : DC000000 000040F4. For the one before the loop (it could have put it after the loop btw, but then I would have to use a negative offset to reach the DC code type address, which would have make it one line longer) : When the codes are executed for the first time, it doesn't matter (0x000040E4 is written over 0x000040E4). But when they have been executed fully at least once, the DC000000 000040E4 has changed to DC000000 000040F4. That C4/00 code combo is used to 'reset' the DC code type to its original value (so the other codes are still able to reach the pointers to the players data, located at pointer+0x40E8~0x40F4 ; if I didn't do that, they'll try to get the pointers from 0x40F8~0x4104) (the 00 code after the C4 code writes to offset + 0x54, ie. [first C4 code type address + 0x54], which points to the data of the DC code type). The C4 code type could also be used to create a place to store data (without having to worry about finding free space in RAM). For exemple, you can store anything in it's data (it's unused), like a counter, or the pad values, or do something like this if you need more space: C4000000 00000000 50000000 00000000 <- will always be false (([offset]=C4000000)!=00000000) E0000000 00000020 00000000 00000000 <- free space 00000000 00000000 <- free space 00000000 00000000 <- free space 00000000 00000000 <- free space D1000000 00000000 ... Then, after the E0 code type, if you add 0x18 to the offset, it'll point to the first 00000000 of the E0 code type, giving you access to some free space (in my exemple 8*32bits of free space) to store anything (one could even imagine to store some game data in there, to be able to backup/restore it). |

so you can like, create a virtual space, is that you're trying to say? or I'm just confuse about the free space thing lol |

| Post subject: | Re: [NDS] Operation Vietnam [US] [AR] |
Erm no, not virtual :/ With the C4 code type, you can use some space inside the code list to store data. That way you don't have to find some free space at an address that could be used by the game at some point. Also you'll be sure that this space will be yours. For exemple, if you create a code and want to store some data (let's say a counter) at 0x02000000. Then someone else (me), that don't know about your code, creates his own code that stores data (let's say the pad values) at 0x02000000. That means if an user use both your and my code, there will obviously be a conflict between the codes. But if we both used a C4 code type to store our data, there couldn't be any conflict at all. edit : another code Code: Infinites medkits/grenades/bombs

Infinite Live works fine also the code for all ammo/medkits/etc... Played about 5 levels Infinite live works for all 4 soldiers I used the NOT C4 codes (My AR = v1.52) I had a lockup when i started a level, but somehow the second try it worked |

Ok, just upgraded my AR to v1.54
