How to make Nintendo DS emulator option – example 1.

For example, consider DeSmuMe SVN r4069 x86

NDS memory map:

MainRAM is 02000000- 02400000 (4Mb)

http://dev-scene.com/NDS/Tutorials_Day_2#Main_Memory

We'll find a zero address using the built-in memory editor (memory viewer).

DeSmuME without a pointer to zero address (speed access to memory is faster without the pointer):, as well as those emulators:

Sony PlayStation - ePSXe

DreamCast, Sega Naomi 1/2, Sammy Atomiswave – Demul (zero address fixed at 2C000000)

SNES – Bsnes, ZSNESWin

Nes – VirtualNes (older versions), puNes, Bsnes, Nintendulator 0.975 beta 9-12-11

Nintendo 64 – 1964, emu-1964, (zero address fixed at 20000000)

PC Engine/Turbografx/CD – Mednafen, PCEjin

Arcade emulator ZiNc (Capcom ZN1/ZN2 based on PSX hardware)

Wonderswan Color, NeoGeo Pocket/Color - Mednafen

Killer Instinct 1/2 – Ultra64 emu

Atari Jaguar – Jagulator

Atari 8-bit, Atari 5200 - Altirra

and others

ArtMoney can select emulator options automatically when loading of ArtMoney table. You can view MD5 file hash in "Process Information" window.

Start the DeSmuMe emulator. Next, open the Process Information and check MD5 hash

Now run Tokyo Beat Down (U), wait until first level is loading, then press Pause button.

Open up your memory window (Tools – View Memory). Select View mode - Words

Exact value search (value at address 02000000 is E7FFDEFFh), type integer 4 byte.

Now change a value at address 02000000 to another value (here it is 11122112h). Then go back to ArtMoney, click the "Filter" button, enter value 11122112h and click OK button. This result is a zero address of emulation

DeSmuMe r4069;DeSmuME_VS2008.exe;N;d5ee44273c2efbd6ceeddf0926464787

;MainRAM 4Mb;02000000;00D38048;400000

Emulator option contains a version of the emulator, MD5 checksum, EXE file name, bytes order, emulator virtual zero address (base address, start of RAM, RAM base), zero address and size of this memory area.

It's necessary to test emulator option on games in two different Windows versions. I made this emulator option in Windows  7 , check the options on the XP SP3

Tokyo Beat Down (U) http://www.artmoney.ru/tables/NintendoDS/Tokyo%20Beat%20Down%20(U).amt

Windows 7

Commando – Steel Disaster (U) http://www.artmoney.ru/tables/NintendoDS/Commando%20-%20Steel%20Disaster%20(U).amt

Windows XP SP3:
