May reset the game every now & then.
Using this code on S&K alone will result with glitches if played as Knuckles because Tails is not fully integrated in this game by itself.

Codes are tested on a real DSi with AR DSi.

there is one version I know is this one: TWL-VSOE-USA

Yeah but these are for the original version, I never heard of the DSi enhanced one. Hey lee4, could you create a page for the normal US version?

[lee4]

I think you are abit confused,

its DS game with DSi enhanced.

there only one version.

check your Game ID is TWL-VSOE-USA

also state which format you are posting

[47iscool]

Yeah that's the same ID, the codes are raw, made with DeSmuME.

[lee4]

just enter the codes into database under that title

Already did, thanks man.

[47iscool]

I have one question about the AR DSi, is it possible to write to ROM addresses? Like the Game Genie does for the NES Genesis & SNES., anybody who has has some insight about this would much appreciated. I know it isn't REALLY writing to the actual ROM offsets but rather redirecting the system to read it's input instead of the ROM cartridge.

[lee4]

Its possible, but I know very little about DS hardware.

I know nothing about the DS and was curious about this. I see the "6004" in that code and I know that in Motorola 68000 assembly that's a branch instruction. Does the DS's assembly also see 6004 as a branch instruction, or maybe it emulates the game, or something else?

It loads the ROMs in the memory, so yeah it's emulated. To get them I just follow patterns to be able to find what I need. Also the when the ROMs are loaded into memory they are in little endian format, so I have to search for byte swapped code.
I was also able to extract the Sonic 1 ROM out of memory, but it won't boot on any emulator, I think they are patched so they won't boot without being in their original state.

So check this out Mr. Hedstrom:

Sonic 1 Skywalking
Decrypted GG Code 00D5CA:0008
DS Version Code: 1217DC58 00000008

They are VERY close.

Just a tip: Make sure you're ending your conditional codes with a D0 or D2 (preferably a D2 line unless you absolutely need a D0) because execution status will always be set to false which will cause your codes to malfunction (even when the condition is met) on real hardware.

[Helder]

Explain to him the Difference of D0 and D2 Demonic since most people don't know.

Well I'm still learning about AR DS codetypes, what are conditional codes? The ones that mean equal to(9??????? or 5????????,
I think I know what you mean because some of them don't all work at the same time. Turning on any code for S&K will make Sonic 1 Codes not work, even if I wanted all of them on at once. I always wondered what D0 or the more common D2 was for.
A note to all about NSMB, I don't have this game ATM, but I will be getting it back, but here's the tip: this game works without the Master Code Datel created.

[lee4]

yes the codes start 5 & 9 needs end with d2 line.

codetypes 3 to A are Conditional codes
